 TogetherJS has two main pieces:
 
-* The [server](https://github.com/mozilla/togetherjs/blob/develop/hub/server.js), which echos messages back and forth between users.  The server doesn't do much, you may gaze upon its incredibly boring [history](https://github.com/mozilla/togetherjs/commits/develop/hub/server.js).
+* The hub in [`hub-worker/`](hub-worker/), which echoes messages back and forth between users.  It doesn't do much: it broadcasts whatever it receives to everyone else in the room, and understands none of it.
 
-* The client in [`togetherjs/`](https://github.com/mozilla/togetherjs/tree/develop/togetherjs) which does all the real work.
+* The client in [`src/`](src/), which does all the real work.
 
 There is no shared hub server anymore, so you'll need to host your own (see "Hosting the Hub Server" in `site/docs/index.md`). The recommended way is [`hub-worker/`](hub-worker/), a Cloudflare Workers + Durable Objects port of the relay logic that runs on Cloudflare's free plan. Note if you include TogetherJS on an https site, you must use an https/wss hub server (Cloudflare Workers handle this automatically).
 
-The files need to be lightly "built": we use [LESS](http://lesscss.org/) for styles, and a couple files are generated.  To develop you need to build the library using [Grunt](http://gruntjs.com/).
-
-To build a copy of the library, check out TogetherJS:
-
-```sh
-$ git clone git://github.com/mozilla/togetherjs.git
-$ cd togetherjs
-```
-
-Then [install npm](http://nodejs.org/download/) and run:
+The client is a set of ES modules under `src/`, bundled with
+[esbuild](https://esbuild.github.io/). To build it, install
+[Node](https://nodejs.org/) 20 or newer and run:
 
 ```sh
 $ npm install
-$ npm install -g grunt-cli
+$ npm run build
 ```
 
-This will install a bunch of stuff, most of which is only used for development.  The only "server" dependency is [WebSocket-Node](https://github.com/Worlize/WebSocket-Node) (and if you use our hub then you don't need to worry about the server).  By default everything is installed locally, i.e., in `node_modules/`.  This works just fine, but it is useful to install the `grunt` command-line program globally, which `npm install -g grunt-cli` does.
+That writes `dist/`:
 
-Now you can build TogetherJS, like:
+* `togetherjs.js` — the whole client, ready to drop into a page with
+  `<script src=".../togetherjs.js"></script>`
+* `togetherjs.min.js` — the same thing, minified, with a source map
+* `togetherjs.esm.js` — an ES module entry, for `import { TogetherJS } from "togetherjs"`
+* `togetherjs.css`, `images/` — the stylesheet and assets
+* `recorder.js`, `walkabout.js` — separate bundles, loaded on demand
 
-```sh
-$ grunt build buildsite --no-hardlink
-```
-
-This will create a copy of the entire `togetherjs.com` site in `build/`.  You'll need to setup a local web server of your own pointed to the `build/` directory. To start a server on port 8080, run:
+To develop, run a watching build with a static server:
 
 ```sh
-$ node devserver.js
+$ npm run dev
 ```
 
-If you want to develop with TogetherJS you probably want the files built continually.  To do this use:
+Then open `examples/index.html`. It expects a hub at `http://localhost:8787`
+(run `npx wrangler dev` inside `hub-worker/`), or you can point it elsewhere
+with `?hub=http://host:port`.
+
+The hub URL baked into a build comes from the `HUB_URL` environment variable:
 
 ```sh
-$ grunt devwatch
+$ HUB_URL=https://hub.example.com npm run build
 ```
 
-This will rebuild when changes are detected.  Note that Grunt is configured to create [hard links](http://en.wikipedia.org/wiki/Hard_link) instead of copying so that most changes you make to files in `togetherjs/` don't need to be rebuilt to show up in `build/togetherjs/`.  `--no-hardlink` turns this behavior off.
+`BASE_URL` does the same for the URL the client's own assets are served from;
+leave it unset and the client works out where it was loaded from.
 
-You may wish to create a static copy of the TogetherJS client to distribute and use on your website.  To do this run:
+Testing
+-------
+
+Unit tests use [Vitest](https://vitest.dev/) and live in `tests/unit/`:
 
 ```sh
-$ grunt build --base-url https://myapp.com --no-hardlink --dest static-myapp
+$ npm test
 ```
 
-Then `static-myapp/togetherjs.js` and `static-myapp/togetherjs-min.js` will be in place, and the rest of the code will be under `static-myapp/togetherjs/`.  You would deploy these on your server.
+End-to-end tests use [Playwright](https://playwright.dev/) and live in
+`tests/e2e/`. They drive two or three real browser contexts through a session
+against an in-process stand-in for the hub, covering cursors, chat, form sync
+and the audio/video mesh:
 
-Running a local server
-----------------------
-You'll need to run your own hub server (see "Hosting the Hub Server" in
-`site/docs/index.md` and [`hub-worker/`](hub-worker/)). If you make changes to
-the hub and want to point a local build at it, set the HUB_URL environment
-variable when building. For example:
-```
-$ HUB_URL=http://localhost:8080 grunt devwatch
+```sh
+$ npm run test:e2e
 ```
 
-Testing
--------
-
-Tests are in `togetherjs/tests/` -- these are [doctest.js](http://doctestjs.org/) tests.  To actually run the tests build togetherjs, serve it up, and go to `http://localhost:PORT/togetherjs/tests/` -- from there the tests are linked to from the top of the page.  The actual tests are `*.js` files in `togetherjs/tests/`, generally `test_*.js` for unit-style tests, and `func_*.js` for functional tests.
-
-The "Manual testing" link is something that lets you simulate different conditions in TogetherJS without setting up a second browser/client.
+Lint with `npm run lint` and format with `npm run format`.
 
-There is unfortunately no automated runner for these tests.  It might be nice if [Karma](http://karma-runner.github.io/) could be setup with doctest.js in general, but so far that isn't done.
+`examples/manual/` holds pages for poking at particular behaviours by hand.

 The core of TogetherJS is the **hub**: this is a server that everyone in a session connects to, and it echos messages to all the participants using Web Sockets.  This server does not rewrite the messages or do much of anything besides **pass the messages between the participants**.
 
-[WebRTC](http://www.webrtc.org/) is available for **audio chat**, but is not otherwise used.  We are often asked about this, as WebRTC offers data channels that allow browsers to send data directly to other browsers without a server.  Unfortunately you still need a server to establish the connection (the connection strings to connect browsers are quite unwieldy), it only supports one-to-one connections, and that support is limited to only some browsers and browser versions.  Also establishing the connection is significantly slower than Web Sockets. But maybe someday.
+[WebRTC](https://webrtc.org/) is used for **audio and video chat**, but not for anything else.  We are often asked about this, as WebRTC offers data channels that let browsers send data directly to each other.  You still need a server to introduce the two browsers, though, and the hub is already there and already fast; a data channel would add a second path to maintain without removing the first.  So application messages continue to go over the Web Socket.
 
 Everything that TogetherJS does is based on these messages being passed between browsers.  It doesn't require that everyone be on the same page, all it requires is that everyone in the session know what hub URL to connect to (the URL is essentially the session name). People *can* be on different sites, but the session URL is stored in [sessionStorage](https://developer.mozilla.org/en-US/docs/Web/API/Window.sessionStorage) which is local to one domain (and because we use sessionStorage instead of localStorage, it is local to one tab).  We don't have any techniques implemented to share sessions across multiple sites, but the only barrier is this local storage of session information.

     When true (default false), TogetherJS treats the entire URL, including the hash, as the identifier of the page; i.e., if you one person is on `http://example.com/#view1` and another person is at `http://example.com/#view2` then these two people are considered to be at completely different URLs.  You'd want to use this in single-page apps where being at the same base URL doesn't mean the two people are looking at the same thing.

+`TogetherJSConfig_enableVideo`:
+    When true (default false), a camera button appears next to the microphone button and participants can share video.  It is off by default because camera access is a bigger ask than the microphone, and because an existing embed should not sprout a camera button when it upgrades.
+
+`TogetherJSConfig_iceServers`:
+    An array of [RTCIceServer](https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/RTCPeerConnection#iceservers) objects used for audio/video connections.  Defaults to a public STUN server.  See "About audio and video chat" below for why you may want to supply a TURN server here.

+`TogetherJSConfig_getIceServers`:

+`TogetherJSConfig_maxRtcPeers`:

 TogetherJS sessions are connected to the domain you start them on (specifically the [origin](http://tools.ietf.org/html/rfc6454)).

We might make this work sometime, but if it's an issue to you please give us [feedback](https://docs.google.com/forms/d/1lVE7JyRo_tjakN0mLG1Cd9X9vseBX9wci153z9JcNEs/viewform).
 
-## About Audio Chat and WebRTC
+## About audio and video chat
+
+Live audio and video chat are based on [WebRTC](https://webrtc.org/), which every current browser supports.
 
-The live audio chat is based on [WebRTC](http://www.webrtc.org/). This is a very new technology, built into some new browsers.
+Click the microphone button to join the call, and click it again to mute yourself.  If you set `TogetherJSConfig_enableVideo`, a camera button appears alongside it; peers who turn their camera on show up as tiles in a video panel.  Audio plays whether or not that panel is open.  "Leave call" in the microphone popup hangs up and releases the microphone and camera.
 
-To enable WebRTC both you and your collaborator need a new browser. Right now, [Firefox Nightly](http://nightly.mozilla.org/) is supported, and we believe that the newest release of Chrome should work.
+### It needs a secure page
 
-Sometime in 2013 support for this should be available in new (non-experimental) versions of Firefox, Chrome, and both Firefox and Chrome for Android.
+Browsers only grant access to the microphone and camera on a secure origin.  If your page is served over plain `http`, the buttons will tell you so — no permission prompt will help, the API is simply not there.  `localhost` counts as secure, so local development works.
 
-To see a summary of outstanding issues that we know of with audio chat see [this page](https://github.com/mozilla/togetherjs/issues?labels=rtc&milestone=&page=1&state=open).
+### It needs TURN on some networks
 
-Note that audio chat will not work between some networks.  These networks require a [TURN server](http://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT) which unfortunately we do not have allocated (and full support for TURN has not landed in some browsers).  Unfortunately when the network makes chat impossible, chat will simply not work – we don't receive an error, and can't tell you why chat is not working.  See [#327](https://github.com/mozilla/togetherjs/issues/327) for progress.
+Everyone in a call connects directly to everyone else.  Some networks — symmetric NATs, and many corporate firewalls — will not allow that, and the connection needs a [TURN server](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT) to relay it.  TogetherJS does not run one, and the default configuration only includes a STUN server, which is enough for most home networks but not all of them.
+
+If your users are on networks where calls fail to connect, supply your own:
+
+```js
+TogetherJSConfig_iceServers = [
+  {urls: "stun:stun.l.google.com:19302"},
+  {urls: "turn:turn.example.com:3478", username: "…", credential: "…"}
+];
+```
+
+TURN credentials are usually short-lived, so if yours are minted per session use the async hook instead:
+
+```js
+TogetherJSConfig_getIceServers = async () => {
+  const resp = await fetch("/my-turn-credentials");
+  return resp.json();
+};
+```
+
+### How many people
+
+The call is a full mesh: each participant sends their audio and video to every other participant separately, so the bandwidth each person needs grows with the number of people.  That is fine for a handful and poor beyond it, so calls are capped at `TogetherJSConfig_maxRtcPeers` (default 6).  Supporting larger calls would mean routing media through a server (an SFU), which TogetherJS does not do.

+TogetherJS client
+=================
+
+The client is a set of ES modules bundled by `build/build.mjs` (esbuild). The
+entry point is `index.js`; everything else is grouped by what it does.
+
+Two conventions are worth knowing before reading any of it:
+
+- **`core/togetherjs.js` is imported, not global.** It defines the `TogetherJS`
+  object and assigns `window.TogetherJS`, but every module that uses it imports
+  it explicitly. Under RequireJS the load order made the global safe to read at
+  module scope; in a single bundle it is not.
+- **Configuration is read lazily.** The bundle evaluates when the `<script>`
+  runs, which is *before* the host page's configuration has been applied, so
+  nothing may read `TogetherJS.config` at module scope.
+
+Modules on an import cycle (session ↔ ui, peers ↔ ui) publish themselves to
+`core/registry.js` and look each other up at call time. A static import would
+evaluate the dependency before the dependent's own body had run.
+
+### `core/`
+
+- `togetherjs.js`: the `TogetherJS` object — configuration, the event mixin,
+  startup state, and the public API surface. Depends on nothing else.
+- `session.js`: the most important module. Sets up the channel, routes
+  messages, tracks peers, and carries the lifecycle events other modules hang
+  off (`session.on("ui-ready")` is fired by `ui.js` but lives here).
+- `channels.js`: abstraction over WebSockets and `postMessage`. Buffers output
+  while the connection opens, handles JSON encoding, reconnects with backoff.
+- `peers.js`: the objects representing other participants and yourself.
+- `storage.js`: per-tab and per-client storage over `localStorage` /
+  `sessionStorage`, with a promise-shaped API.
+- `startup.js`: what to show when a session first starts — browser warnings,
+  the intro, the walkthrough, the share link.
+- `who.js`: peeks into another room's occupants without joining it.
+- `console.js`: TogetherJS's own log collector.
+- `util.js`: general-purpose support code — a class pattern, assertions, the
+  event mixin, and `util.Deferred`, a native-promise deferred that keeps the
+  progress notifications a couple of callers rely on.
+- `registry.js`: the lazy-module registry described above.
+
+### `dom/`
+
+- `dom.js`: the jQuery replacement. Provides the subset of the jQuery API the
+  client actually used, and nothing more.
+- `animate.js`: the UI's animations, on the Web Animations API and CSS
+  transitions.
+- `elementFinder.js`: generates a locator for any element and finds elements
+  from those locators, so peers can point at each other's DOM. Also decides
+  which elements to ignore (TogetherJS's own, mostly).
+- `templating.js`: builds nodes from DOM templates, substituting by class name.
+- `eventMaker.js`: synthesises events, such as a fake click.
+- `linkify.js`: turns URLs in text into links.
+
+### `ui/`
+
+- `ui.js`: most of the interface. Loads the markup and binds the controls;
+  `ui.activateUI()` is the entry point.
+- `windowing.js`: windows, notifications and modals.
+- `chat.js`: chat logic and the slash commands. The chat UI itself is in
+  `ui.js`.
+- `walkthrough.js`: the first-run walkthrough.
+- `visibility.js`: normalises the Page Visibility API into a session event.
+
+### `sync/`
+
+- `cursor.js`: shared cursors and clicks — both capture and display.
+- `forms.js`: form field synchronisation, including Ace, CodeMirror, CKEditor
+  and TinyMCE.
+- `ot.js`: operational transformation, which is what keeps text fields
+  consistent when two people type into one at the same time.
+- `videos.js`: `<video>` / `<audio>` play, pause and seek.
+- `youtube.js`: the same for embedded YouTube players.
+
+### `rtc/`
+
+Audio and video calling. See the header comment in `rtc/index.js`; the short
+version is one `RTCPeerConnection` per peer, negotiated with the WebRTC spec's
+perfect-negotiation pattern.
+
+- `media.js`: the local microphone and camera.
+- `connection.js`: a single peer connection.
+- `mesh.js`: the set of connections, and the signaling.
+- `ui.js`: the dock buttons and the video tiles.
+
+### Other
+
+- `templates/`: `interface.html`, `walkthrough.html`, `help.txt` and the
+  `locale/*.json` translations. `build/templates.mjs` renders one copy per
+  locale into `generated.js`, which is bundled; `templates.js` picks the right
+  one at runtime.
+- `styles/`: plain CSS. Design tokens are custom properties on `:root`, so a
+  host page can restyle the client.
+- `vendor/`: third-party code. `walkabout/` (a fuzz tester, loaded on demand by
+  the `/test` chat command) and `whrandom/` (a seeded PRNG, used by tests).
+- `recorder.js` / `playback.js`: the `/record` and `/playback` commands.
+  `recorder.js` is its own bundle, loaded by `examples/recorder.html`.
+- `randomutil.js`: seeded random helpers, for tests.

+/* SimpleHistory synchronizes peers by relying on the server to serialize

+ * which have not yet been 'committed' (by being echoed back from the
+ * server).  The client is responsible for transposing its own queue
+ * if 'earlier' patches are heard from the server.
+ *
+ * Let's say that A's edit "1" and B's edit "2" occur and get put in
+ * their respective SimpleHistory queues.  The server happens to
+ * handle 1 first, then 2, so those are the order that all peers
+ * (both A and B) see the messages.
+ *
+ * A sees 1, and has 1 on its queue, so everything's fine. It
+ * updates the 'committed' text to match its current text and drops
+ * the patch from its queue. It then sees 2, but the basis number
+ * for 2 no longer matches the committed basis, so it throws it
+ * away.
+ *
+ * B sees 1, and has 2 on its queue. It does the OT transpose thing,
+ * updating the committed text to include 1 and the 'current' text
+ * to include 1+2. It updates its queue with the newly transposed
+ * version of 2 (call it 2prime) and updates 2prime's basis
+ * number. It them resends 2prime to the server. It then receives 2
+ * (the original) but the basis number no longer matches the
+ * committed basis, so it throws it away.
+ *
+ * Now the server sees 2prime and rebroadcasts it to both A and B.
+ *
+ * A is seeing it for the first time, and the basis number matches,
+ * so it applies it to the current and committed text.
+ *
+ * B sees that 2prime matches what's on the start of its queue,
+ * shifts it off, and updates the committed text to match the
+ * current text.
+ *
+ * Note that no one tries to keep an entire history of changes,
+ * which is the main difference with ot.History.  Everyone applies
+ * the same patches in the same order.

-TogetherJS client
-=================
-
-This is all the files for the TogetherJS client.
-An overview of the modules:
-
-- `libs/`: contains external libraries, sometimes as [git subtree inclusions](https://github.com/apenwarr/git-subtree) and sometimes just copied in.
-
-- `analytics.js`: a little library for handling Google Analytics opt-in support
-
-- `channels.js`: abstraction over WebSockets and other communication methods (like `postMessage`).  Buffers output while the connection is opening, handles JSON encoding/decoding.
-
-- `chat.js`: handles the chat code, including logging old chat messages.  Doesn't actually include the chat UI, which is in `ui.js`
-
-- `cursor.js`: handles the shared cursors, both displaying and capturing events.  Also handles clicks.  This *does* include the relevant UI.
-
-- `elementFinder.js`: this generates a description/locator/path for any element, and finds elements based on those paths.  It generates something similar to a CSS selector.  It also includes a function to determine what elements should be ignored (generally TogetherJS's own elements).
-
-- `eventMaker.js`: this creates artificial events, like a fake click event.
-
-- `forms.js`: handles synchronization of forms, including CodeMirror and ACE support.
-
-- `jqueryPlugins.js`: some plugins for jQuery; doesn't export anything.
-
-- `linkify.js`: detects and adds links to plain text.
-
-- `ot.js`: operational transformation support: what keeps big chunks of text in sync when multiple people are simultaneously editing those fields.
-
-- `peers.js`: handles the objects representing the peers and oneself.
-
-- `playback.js`: handles the magic `/playback` command that plays recordings.
-
-- `randomutil.js`: some functions/methods for random numbers, really just for testing.
-
-- `recorder.js`: this is used by `recorder.html`, which is a kind of alternate mini-client used to record sessions when you put `/record` in the chat box.
-
-- `session.js`: probably the most important and most core module in the system.  This sets up the channels, routes messages, tracks peers, and is used for some communication (like `session.on("ui-ready")` - which is actually signalled by `ui.js` but is fired on the session module).
-
-- `startup.js`: handles the logic of what to display when TogetherJS is first started up (including warning messages, introductory stuff, the share link, confirmation of joining the session)
-
-- `storage.js`: an abstraction of per-tab and client storage.  Mostly uses `localStorage` (or `sessionStorage`), but designed so it could use an async backed someday, perhaps.
-
-- `templates.js`: this is generated dynamically, and includes the `*.html` content as inlined strings.  Basically just a container for these strings.
-
-- `templating.js`: handles creating nodes based on DOM templates.  Does some substitution based on specific class names.
-
-- `togetherjs.js`: this is the bootstrap code.  It is included on all pages, defines the `TogetherJS` variable, and handles configuration and initial loading.
-
-- `ui.js`: this has most of the UI.  It loads the UI and binds most of the methods.  It's a jumble of UI stuff.  `ui.activateUI()` is the most important function.
-
-- `util.js`: several bits of abstract support code are in here.  It doesn't depend on other things, and has fairly abstract general-purpose code.  It includes a pattern for creating classes, assertions, events.
-
-- `walkthrough.js`: implements the walkthrough help.
-
-- `webrtc.js`: handles the live audio chat and avatar editing.
-
-- `windowing.js`: handles creating the different windows, notifications, and modal windows.

-  /* SimpleHistory synchronizes peers by relying on the server to serialize

-   * which have not yet been 'committed' (by being echoed back from the
-   * server).  The client is responsible for transposing its own queue
-   * if 'earlier' patches are heard from the server.
-   *
-   * Let's say that A's edit "1" and B's edit "2" occur and get put in
-   * their respective SimpleHistory queues.  The server happens to
-   * handle 1 first, then 2, so those are the order that all peers
-   * (both A and B) see the messages.
-   *
-   * A sees 1, and has 1 on its queue, so everything's fine. It
-   * updates the 'committed' text to match its current text and drops
-   * the patch from its queue. It then sees 2, but the basis number
-   * for 2 no longer matches the committed basis, so it throws it
-   * away.
-   *
-   * B sees 1, and has 2 on its queue. It does the OT transpose thing,
-   * updating the committed text to include 1 and the 'current' text
-   * to include 1+2. It updates its queue with the newly transposed
-   * version of 2 (call it 2prime) and updates 2prime's basis
-   * number. It them resends 2prime to the server. It then receives 2
-   * (the original) but the basis number no longer matches the
-   * committed basis, so it throws it away.
-   *
-   * Now the server sees 2prime and rebroadcasts it to both A and B.
-   *
-   * A is seeing it for the first time, and the basis number matches,
-   * so it applies it to the current and committed text.
-   *
-   * B sees that 2prime matches what's on the start of its queue,
-   * shifts it off, and updates the committed text to match the
-   * current text.
-   *
-   * Note that no one tries to keep an entire history of changes,
-   * which is the main difference with ot.History.  Everyone applies
-   * the same patches in the same order.

-## doctest.js
-
-For a more complete description please [read the main
-page](http://doctestjs.org).
-
-`doctest.js` is a test runner for Javascript, organized around *examples* and *expected result*.  Tests look like this:
-
-```javascript
-// Simple stuff:
-print(3 * 4);
-// => 12
-
-// Or complicated stuff:
-var complete = false;
-var savedResult = null;
-$.ajax({
-  url: "/test",
-  dataType: "json",

-<h2>Doctest.js: examples</h2>
-
-<div id="contents"></div>
-
-<div id="doctest-output"></div>
-
-<h3>Web Service</h3>
-
-<div>
-  You can use doctest.js to test APIs; in fact, it's reasonable to use
-  it for acceptance tests of the web APIs themselves, not just to test
-  the Javascript wrappers around those APIs.
-</div>
-
-<div class="test">
-  In this example we'll access the <a
-  href="http://www.geonames.org/export/web-services.html">Geonames
-  API</a>.  First we'll want some routines to help us later on.  You
-  could put these into a separate <code>.js</code> file and include
-  it, but often (especially in an example ;) it's best to be fully
-  transparent and list all the routines out in the open...
-
-<pre class="doctest">
-$ apiLocation = 'http://ws.geonames.org/';
-$ function query(endpoint, q) {
->   var url = apiLocation + endpoint;
->   jQuery.ajax({
->     url: url,
->     data: q,
->     dataType: "json",
->     success: Spy('success', {wait: true, ignoreThis: true}),
->     error: Spy('error')
->   });
-> }
-</pre>
-
-  Some things to notice about this example:
-
-  <ul>
-    <li><code>apiLocation</code> is hard coded, but you could read it
-    from the query string, allowing something like
-    <code>test.html?apiLocation=http://localhost:8080</code>.
-    </li>
-
-    <li>We create a Spy for both success and failure, as we want to
-    track both of these.  We could just use functions, but mostly
-    there's an advantage to being able to watch <code>.called</code>.
-    If you used <code>{writes: true}</code> you might not need the
-    <code>.applies</code> functions.
-    </li>
-
-    <li><code>wait</code> can be called from anywhere.  That means
-    when you call this function doctest will wait until something is
-    called, and will test all the output since that time (either the
-    success or failure <code>writeln()</code>).  Timeout is the other
-    possibility.
-    </li>
-  </ul>
-
-</div>
-
-<div>
-  Now we'll use the routine to actually run a test:
-
-<pre class="doctest">
-$ query('postalCodeSearchJSON', {postalcode: 9011, maxRows: 5});
-success({
-  postalCodes: [
-    {...}
-  ]
-}, ...)
-</pre>
-
-</div>
-
-<h3>Web Service/XML</h3>
-
-<div class="test">
-  What we do for JSON, we can also do for XML; in this case
-  it's just fetching a static XML Atom document.
-
-<pre class="test">
-$.ajax({
-  url: './.resources/example.xml',
-  dataType: 'xml',
-  success: function (doc) {
-    gdoc = doc;
-    writeln(repr(doc));
-  },
-  error: Spy('error')
-});
-wait(0.5);
-/* =>
-&lt;feed xmlns="http://www.w3.org/2005/Atom">
-  &lt;title>Example Feed&lt;/title>
-  ...
-&lt;/feed>
-*/
-
-</pre>
-
-</div>
-
-<h3>Deferred/Promise</h3>
-
-<div class="test">
-
-  You can also
-  print <a href="http://api.jquery.com/category/deferred-object/">jquery.Deferred</a>
-  (promise) objects once they've resolved, using
-  the <code>printResolved()</code> function.  This also implicitly
-  calls <code>wait()</code> with the condition that all the promises
-  be resolved.  Both errors and resolved values are printed.
-
-  <pre class="test">
-var def1 = $.Deferred();
-var def2 = $.Deferred();
-def1.resolve("Value 1!", "Value2!");
-setTimeout(function () {
-  def2.reject("sucka");
-}, 500);
-printResolved("def1", def1, "def2", def2);
-// => def1 Value 1! Value2! def2 Error: sucka

-
-<p><strong>Doctest.js</strong> is a test runner and testing framework for Javascript.</p>
-
-<p>Doctest uses a novel approach to testing: <em>example</em> and <em>expected result</em>.  Each test is a chunk of code that prints out results and side effects, and then the expected result is matched against that to see if the test passed or failed.</p>
-
-<p>An example (note: these are live examples &mdash; you can also try your own via the <a href="try.html">live demo</a>):
-
-<pre class="test">
-function capitalize(words) {
-  return words.replace(/\b[a-z]/g, function (m) {
-    return m[0].toUpperCase();
-  });
-}
-
-print(capitalize('some words'));
-// => Some Words
-
-print(capitalize('some 4ward words'));
-// => Some 4ward Words
-</pre>
-</p>
-
-<p>This is similar to something like <code>assertEqual(capitalize('some words'), 'Some Words')</code> &mdash; there's a kind of "equal" check every time you print something.  Instead of doing stuff then testing every detail of what happened or what was returned, testing almost happens for you &mdash; you print out what you are interested in, and you can even punt: you can start by simply exercising everything that matters, and then inspecting that what happens is what you expect, and copying those results into the test.  For instance:
-
-<pre class="test">
-function getProperties(obj) {
-  var result = [];
-  for (i in obj) {
-    result.push(i);
-  }
-  result.sort();
-  return result;
-}
-
-print(getProperties({b: 1, a: 2}));
-// =>
-
-print(getProperties("a"));
-// =>
-</pre>
-
-</p>
-
-<p>Look: the first example worked great, <code>["a", "b"]</code>.  The second example though wasn't right at all.  <code>"0"</code>?  Once we have a better idea we can adjust those tests:
-
-<pre class="test">
-function getProperties(obj) {
-  var result = [];
-  for (i in obj) {
-    if (obj.hasOwnProperty(i)) {
-      result.push(i);
-    }
-  }
-  result.sort();
-  return result;
-}
-
-print(getProperties({b: 1, a: 2}));
-// => ["a", "b"]
-
-print(getProperties("a"));
-// => []
-</pre>
-
-Well, that wasn't quite enough, but this kind of incremental development is exactly why doctest.js is so helpful: it shows you what you've done, it shows you both <em>presence</em> and <em>absence</em>. Most test frameworks only give you tools to test what <em>is</em> there, and not ensure that the things you don't want aren't there.</p>
-
-<h3>Async testing made easy!</h3>
-
-<p>The other <strong>great</strong> feature of doctest.js is how it lets you test async code.</p>
-
-<p>Async code is a bit tricky for all test runners.  When you run the test, the <em>result</em> of the test won't be known until after you wait some time.  Test runners might have ways to pause the test process while the test code completes.  They also need ways to test that everything you wanted to happen will happen.  Something that is often tricky in test code is to <em>make sure</em> that some callback was called &mdash; it's relatively easier to test that the callback was called correctly.</p>
-
-<p>Here doctest's ability to test both what's present and what's missing shines.  And the test runner also gives you a great way to serialize your asynchronous tests.</p>
-
-<p>The core feature here is <code>wait()</code> &mdash; this lets you register a callback that will tell the test runner when this block of code is fully finished.  An example:
-
-<pre class="test">
-var now = Date.now();
-var done = false;
-
-setTimeout(function () {
-  done = true;
-  print('The timeout finished!', Date.now() - now);
-}, 300);
-
-wait(function () {return done;});
-// => The timeout finished! ...
-</pre>
-
-(Notice we use <code>...</code> to ignore the specific number that is printed: ellipsis act as a kind of wildcard)
-
-</p>
-
-<p>With Doctest you don't have to use fake <code>setTimeout</code> or fake async anywhere &mdash; you always use the real thing, and it's nearly as easy to test as async code.  Frameworks that make this code synchronous are cheating you, because asynchronous code is the hardest of code and deserves to be tested accurately.  But when a test framework makes synchronous easy and asynchronous hard, it's all too easy when in the depth of test development to take shortcuts.</p>
-
-<h3>Mocking with Spy</h3>
-
-<p>In addition there's a simply mocking framework in doctest with Spy. This lets you create a function that records over time it is called &mdash; and each time it is called it prints out how it is called. It also makes it easy to wait on the Spy to be called:
-
-<pre class="test">
-var button = $('&lt;button>&lt;/button>');
-$('body').append(button);
-button.click(Spy('button.click'));
-button.click();
-Spy('button.click').wait();
-/* =>
-&lt;button />.button.click({...})
-*/
-</pre>
-
-You'll notice here that we also ignored the details of the object passed to the callback.  We could use wildcards to match no part or any specific part of the argument called.  Also note that the value of <code>this</code> is shown: people usually forget that <code>this</code> is a kind of implicit argument to many functions, but again doctest makes the implicit explicit.  Also note that the <em>actual</em> output is always displayed, so you can use this to inspect aspects of the environment even if you don't want to test all fo them.
-</p>
-
-
-<h3>Lineage</h3>
-
-<p>Doctest is based on the Python <a href="http://docs.python.org/library/doctest.html">doctest module</a> originally written by Tim Peters.  Spy was inspired some by Jasmine's <a href="http://pivotal.github.com/jasmine/jsdoc/symbols/jasmine.Spy.html">Spy class</a>, and carries over ideas from <a href="http://pypi.python.org/pypi/MiniMock">MiniMock</a>.</p>
-
-<p>If you've used Python's doctest and found it annoying or not widely useful for doctest: <strong>doctest.js fixes all those problems</strong>: see <a href="http://blog.ianbicking.org/2012/10/02/why-doctest-js-is-better-than-pythons-doctest/">this post for more</a>.</p>

-Author: Ian Bicking,
-<a href="mailto:ian@ianbicking.org">ian@ianbicking.org</a>
-</p>
-
-<div id="contents"></div>
-
-<h3 id="html">HTML page</h3>
-
-<p>Your HTML page needs just a couple things to set it up for a test:
-
-<pre>
-&lt;html>
- &lt;head>
-  &lt;script src="doctestjs/doctest.js">&lt;/script>
-  &lt;link href="doctestjs/doctest.css" rel="stylesheet">
- &lt;/head>
- &lt;body class="autodoctest">
-
-  &lt;pre class="test / doctest">
-    test
-  &lt;/pre>
- &lt;/body>
-&lt;/html>
-</pre>
-
-</p>
-
-<p>Notably you need <code>&lt;body <strong>class="autodoctest"</strong>></code> to get the tests to run automatically on page load.  If you were invoking doctest explicitly (like is done on the <a href="try.html">Try It</a> page) then you might leave this off.</p>
-
-<h4 id="external">External code</h4>
-
-<p>Often you won't want to write your test code inside the test itself.  Instead you'll want to put it in its own <code>.js</code> file.  Especially with <a href="#format-test"><code>test</code></a> the code is valid Javascript, and you will probably want syntax highlighting and all that.</p>
-
-<p>To do this, use an <code>href</code> attribtue on your <code>&lt;pre></code> element, like:
-
-<pre>
-&lt;pre class="test" href="./tests.js">&lt;/pre>
-</pre>
-
-The contents of the element don't matter.  The test will be loaded from that location (which could be a full URL but you'll probably have <a href="http://www.w3.org/TR/cors/">cross-origin</a> errors if you tried that &mdash; this doesn't use <code>&lt;script></code> tags to load those scripts, it uses XMLHttpRequest).  Note that the class is still required!</p>
-
-<p>You can also load it from a variable location, using query string parameters to find the file.  The most common pattern would be like this:
-
-<pre>
-&lt;pre class="test" data-href-pattern="./{test-name|default.js}">&lt;/pre>
-</pre>
-
-Any URL parameters (like <code>{test-name}</code>) get filled in by the query string (<code>?test-name=example.js</code>).  By default these values can only contain letters, numbers, <code>_</code>, <code>-</code> and <code>.</code> &mdash; this is to protect against loading scripts from unexpected locations via an implicitly unsafe parameters in the query string.</p>
-
-<p>If you want to use a different restriction on a variable name, use <code>{variable-name:regular_expression}</code> &mdash; and use <code>^</code> and <code>$</code> to make sure to match the entire string.</p>
-
-<p>If you want a default (if the parameter isn't set or is empty) use <code>|</code> to separate out the default.  The default should come after the regular expression.  In the example the default is <code>default.js</code>.  Don't use extra spaces around <code>|</code>!</p>
-
-<p>Note this works well with relative addresses like <code>&lt;a href="?test-name=foo.js">foo.js&lt;/a></code></p>
-
-<h3 id="format">Format of test</h3>
-
-<p>There are two formats that a doctest can take.  You've probably seen the <code>test</code> format, there is also the more traditional <code>doctest</code> format.</p>
-
-<h4 id="format-doctest"><code>doctest</code> format</h4>
-
-<p>This format is used like:
-
-<pre>
-&lt;pre class="doctest">
-$ first_line();
-> continuation line
-output
-&lt;/pre>
-</pre>
-
-</p>
-
-<p>The first line of course starts wtih <code>$</code> and a space. Think of it like a Unix command line.  And also similar to a command line shell the continuation line is <code>></code>.  Any line <em>without</em> a leading <code>$</code> or <code>></code> is considered expected output.</p>
-
-<p>Note you can still have multiple statements using a continuation line.  The only difference between two lines with <code>$</code> and one with a <code>$</code> followed by <code>></code> is that in the latter case the two lines are executed <em>together</em> and the output from both is combined into what is expected.</p>
-
-<h4 id="format-test"><code>test</code> format</h4>
-
-<p>In this format the expected output is in a comment, like:
-
-<pre>
-&lt;pre class="test">
-statement_1();
-statement_2();
-// Some other comment
-// => expected output
-
-More statements
-
-/* =>
-expected output
-*/
-</pre>
-
-</p>
-
-<p>Basically the test is split up by using the <code>// =></code> comments.  Each chunk is executed independently, and the test may be paused at the point where the expected output is found.</p>
-
-<h4 id="sections">Test sections</h4>
-
-<p><em>If</em> you are using <a href="#external">external test code</a> (and <code>test</code>) you can include <em>section headers</em> like:
-
-<pre>
-// == SECTION A section header
-</pre>
-
-</p>
-
-<p>You can have one or more <code>=</code>'s.  The text <code>A section header</code> will become a header.  Each section header turns into a new <code>&lt;pre></code> element.</p>
-
-<h4 id="compact">Compact <code>&lt;pre></code>'s</h4>
-
-<p>Sometimes you'll have boilerplate code that sets up the test environment, and you'll be uninterested in that code (unless it fails).  This might define helper functions, or run some really routine sanity tests.  You can use this to make those test blocks small:
-
-<pre>
-&lt;pre class="test expand-on-failure">
-  ...
-&lt;/pre>
-</pre>
-
-This will make the test 3em tall unless there's a failure, at which point it expands to its full size.</p>
-
-<h3 id="print">Printing/writing</h3>
-
-<p>The <code>print()</code> function is pretty important, of course. (Note it also was called <code>writeln()</code>, a name which is still supported).</p>
-
-<p><code>print()</code> will print out any strings given to it, and the <code>repr()</code> of any other objects, with a space between each argument.</p>
-
-<p>You can make a <strong>custom <code>repr()</code></strong> for any object by adding a <code>.repr()</code> method.  It should look like:
-
-<pre>
-MyObject.prototype.repr = function () {
-  return '[MyObject attr: ' + repr(this.attr) + ']';
-};
-</pre>
-
-</p>
-
-<p>If you can't add a method to your object, you can also add a stringifier using <code>repr.register()</code>.</p>
-
-<p>You might do this like:
-
-<pre>
-repr.register(
-  function (o) {
-    return o instanceof MyClass;
-  },
-  function (o, indentString) {
-    return '[MyClass attr: ' + repr(o.attr) + ']';
-  }
-);
-</pre>
-
-The first function is a <em>test</em> that is applied to objects.  If it returns true, then the second function is called to stringify the object.  <em>If</em> your representation uses multiple lines, then you should indent subsequent lines with the string, like <code>return '[Beginning\n' + indentString + '  end\n' + indentString + ']';</code>.  The beginning is never indented.
-
-</p>
-
-<p>Some of the objects that have custom representations:</p>
-
-<dl>
-  <dt>XML and DOM objects</dt>
-  <dd>These are displayed as the normal serialization, e.g., <code>&lt;input type="text" /></code>.  XML-style endings for empty tags are always used.  Attributes are alphabetized.  HTML tags are upppercase and attributes are lowercase, because the DOM seems to like that.</dd>
-
-  <dt>XMLHttpRequest</dt>
-  <dd>These are displayed like <code>[XMLHttpRequest STATE [STATUS]]</code>.  The <code>STATE</code> is one of <code>UNSENT</code>, <code>OPENED</code>, <code>HEADERS_RECEIVED</code>, <code>LOADING</code> and <code>DONE</code>.  The <code>[STATUS]</code> is only displayed if the request has finished.</dd>
-
-</dl>
-
-<p>Arrays and objects are displayed like you'd think.  This might include objects that you might not think of as "plain" objects.  Also the object prototype is not displayed.  You'll have to use something like <code>print(o.constructor)</code> if you want to be specific about classes.</p>
-
-<h4 id="console"><code>console.log()</code></h3>
-
-<p><code>console.log()</code> works a lot like <code>print()</code>. But unlike <code>print()</code> it doesn't make a test pass or fail, it's purely informative.</p>
-
-<p>All the methods on console should work, like <code>console.warn()</code>.  The underlying normal console function is called, but in addition on a test-by-test basis these are collected and displayed.</p>
-
-<h4 id="printResolved"><code>printResolved()</code> for Deferred and Promises</h4>
-
-<p>There's special support for the jQuery <a href="http://api.jquery.com/category/deferred-object/">Deferred</a> object, and generally <a href="http://wiki.commonjs.org/wiki/Promises/A">Promises/A</a>.</p>
-
-<p>This support is through the <code>printResolved()</code> function, which is basically equivalent to <code>print()</code> except any promise arguments will be waited on to resolve (proper resolution or an error).  You can use it like this:</p>
-
-<pre class="test">
-var def = $.Deferred();
-setTimeout(function () {
-  def.resolve("Resolved!");
-});
-printResolved(def);
-// => Resolved!
-</pre>
-
-<p>Errors are printed out with <code>Error:</code> before the value, and multiple arguments are printed out with spaces between them, or a placeholder if there's no arguments.  For instance:</p>
-
-<pre class="test">
-var def = $.Deferred();
-def.reject({code: 1}, "a message");
-printResolved(def);
-// => Error: {code: 1} a message
-// Or you might not have any value at all:
-def = $.Deferred();
-def.resolve();
-printResolved(def);
-// => (resolved)
-</pre>
-
-<h3 id="matching">Output matching</h3>
-
-<p>The <em>expected</em> output is compared with the output you actually <em>got</em> (received).</p>
-
-<p>First all whitespace is normalized.  Empty lines are removed from both sides.  Leading spaces are removed (i.e., indentation does not matter).  Multiple spaces are normalized to a single space.</p>
-
-<p>There are two wildcard patterns.  Ellipsis &mdash; <code>...</code> &mdash; means "match anything".  This will match zero character, or multiple lines.  You should be careful about matching <em>too</em> much.</p>
-
-<p>The shorter wildcard is <code>?</code>.  This matches letters, numbers, underscore, period, and question mark.  Note if you want to match a string with such characters you might have to use <code>"?"</code>.</p>
-
-<p>Also a special case, <code>&quot;</code> matches <code>'</code> and vice versa.  Since in most contexts these mean the same thing, this lets you be agnostic.</p>
-
-<p>When you have a large expected text and got a lot of text, and that text differs just a bit, you'll see a line-by-line comparison of the two, to help you identify exactly where the problem is.  Note if you use wildcards the line-by-line comparison might be very inaccurate.</p>
-
-<h3 id="wait"><code>wait()</code>, async code, and pausing the tests</h3>
-
-<p>Often you'll want to let code run for a while on its own before you are done with testing a section of code.  I.e., you want to let all the requests complete, DOM elements update, and so forth.</p>
-
-<p>Each <em>section</em> of code can be paused at the end. <strong>Code cannot be paused in the middle of a section.</strong>  So before the output (i.e., before <code>// =></code>) the test runner can wait and collect output.<p>
-
-<p>Anytime you call <code>wait()</code> inside a section of code it tells the test runner to wait <em>at the end of the test</em>, either until some condition is true or until some time has passed.  If the condition doesn't complete an error/timeout message is <code>print()</code>'d.</p>
-
-<p>A half baked version of what happens is this:
-
-<pre>
-var printed = [], waiting = null;
-function print(arg) {
-  printed.push(arg);
-}
-function wait(condition) {
-  waiting = condition;
-}
-function checkOutput() {
-  if (printed.join('\n') != expectedOutput) {
-     fail();
-  }
-}
-eval(exampleCode);
-hardTimeout = 5000; // 5 seconds
-checkTime = 100; // check every 0.1 seconds
-if (waiting === null) {
-  checkOutput();
-} else if (typeof waiting == "number") {
-  setTimeout(checkOutput, waiting);
-} else {
-  var now = Date.now();
-  function checker() {
-    if (waiting()) {
-      checkOutput();
-    } else if (Date.now() - now > hardTimeout) {
-      print("Error: timed out");
-      checkOutput();
-    } else {
-      setTimeout(checker, hardTimeout);
-    }
-  }
-  setTimeout(checker, 0);
-}
-</pre>
-
-Now you practically know how to write doctest yourself!
-</p>
-
-<p>Specifically this is how you can run <code>wait()</code>:</p>
-
-<dl>
-  <dt><code>wait()</code></dt>
-  <dd>This makes the test pause just for a moment.  It's the same as <code>wait(0)</code>.</dd>
-
-  <dt><code>wait(milliseconds)</code></dt>
-  <dd>This forces the test to pause for the given number of milliseconds.  Everything is always in milliseconds.</dd>
-
-  <dt><code>wait(condition)</code></dt>
-  <dd>This calls <code>condition()</code> frequently until it returns true.</dd>
-
-  <dt><code>wait(condition, timeout)</code></dt>
-  <dd>This calls condition up until <code>timeout</code> milliseconds. You can use this to extend the timeout.  The default timeout is 5 seconds (5000).</dd>
-</dl>
-
-<h3 id="spy">Spy, mocking, and watching functions</h3>
-
-<p><code>Spy</code> is used to create a mock object/function that can be used to track calls and inspect call order and arguments.</p>
-
-<p>The basic use is like this:
-
-<pre class="test">
-func = Spy('func');
-func(1, 2, 3);
-
-obj = {a: 1, func: func};
-obj.func();
-
-/* =>
-func(1, 2, 3)
-{a: 1, func: Spy('func')}.func()
-*/
-</pre>
-
-</p>
-
-<p>That is, every time the Spy is called it will print out the call, all its arguments, and if there was a bound <code>this</code> (as in the <code>obj.func()</code> example) then that value will be displayed as well.</p>
-
-<p>Each spy is <em>named</em>, and if you call <code>Spy(name)</code> with a name that has been used before you will get the same Spy object back.</p>
-
-<p><code>Spy</code> can be invoked in a couple ways:</p>
-
-<dl>
-  <dt><code>Spy(name)</code></dt>
-  <dd>Just creates/gets the Spy with the given name.</dd>
-
-  <dt><code>Spy(name, {options})</code></dt>
-  <dd>Create the Spy with some options (as described below)</dd>
-
-  <dt><code>Spy(name, function () {...})</code></dt>
-  <dd>Creates a Spy that wraps another function that you provide.  The Spy will be called first, and will print out the call, and then it will call the sub-function with the same arguments and <code>this</code>.</dd>
-
-  <dt><code>Spy(name, function () {...}, {options})</code></dt>
-  <dd>Create a Spy that wraps a function and has extra options.</dd>
-
-</dl>
-
-<p>Note that your function can raise an exception, and the Spy will pass it through (though also note the exception using <code>console.log()</code>).  You can use this to inspect how a library reacts to exceptions in callbacks.</p>
-
-<h4 id="spy-options">Spy options</h4>
-
-<p>The options available:</p>
-
-<dl>
-  <dt><code>applies: function () {...}</code></dt>
-  <dd>This is the function that will be called when the Spy is called. It's the same as passing in the function as the second argument.</dd>
-
-  <dt><code>writes: false</code> (default <code>true</code>)</dt>
-  <dd>If this is false (default true) then it will <em>not</em> print out the call.</dd>
-
-  <dt><code>returns: value</code> (default <code>undefined</code>)</dt>
-  <dd>This is what the Spy returns when called (assuming you did not use <code>applies</code>).  By default it simply returns <code>undefined</code>, which is what a function returns when you have no explicit <code>return</code> statement.</dd>
-
-  <dt><code>throwError: exceptionObject</code></dt>
-  <dd>If given, when the Spy is called it'll do <code>throw exceptionObject</code></dd>
-
-  <dt><code>ignoreThis: true</code> (default <code>false</code>)</dt>
-  <dd>If true, then <code>this</code> won't be printed out regardless of whether it is bound.  This is useful when a library binds <code>this</code> carelessly.</dd>
-
-  <dt><code>wrapArgs: true</code> (default <code>false</code>)</dt>
-  <dd>If true then wrapping will be forced when the arguments are printed out.  Otherwise wrapping is only applied if an argument is longer than 80 columns (the default for printing generally).</dd>
-
-  <dt><code>wait: true</code> (default <code>false</code>)</dt>
-  <dd>This is equivalent to calling <code>Spy(name).wait()</code>. You can also pass in a number, which will be the millisecond timeout, e.g., <code>Spy(name, {wait: 10000})</code> to wait for 10 seconds for the Spy to be called.</dd>
-
-  <dt><code>methods: {...}</code></dt>
-  <dd>Equivalent to calling <code>Spy.methods({...})</code>.  See below for details.</dd>
-
-</dl>
-
-<p>You can also change <code>Spy.defaultOptions</code> if you want to override one option by default, for instance to turn off printing or ignore <code>this</code>.</p>
-
-<h4 id="spy-methods">Spy methods</h4>
-
-<p>Several methods are available:</p>
-
-<dl>
-  <dt><code>Spy().wait([timeout])</code></dt>
-  <dd>This makes the test pause until the Spy has been called. Sometimes you <em>must</em> use the method instead of <code>Spy(name, {wait: true})</code>.  An example:
-
-    <pre>
-SomeAPI.onload = Spy('SomeAPI.onload', function (data) {
-  SomeOtherAPI.save(data, Spy('SomeOtherAPI.save'));
-};
-Spy('SomeOtherAPI.save').wait();
-/* =>
-SomeAPI.onlaod({...})
-SomeOtherAPI.save()
-*/
-</pre>
-
-    In this case the Spy is created <em>inside</em> another method, and that method is not called right away.  <code>wait: true</code> doesn't work in this case.  Instead you should call <code>Spy(name).wait()</code> later.  Since names are unique, this will be the same Spy object as referenced earlier.
-</dd>
-
-  <dt><code>Spy.on("obj.attr", [applies/options])</code></dt>
-  <dd>This replaces the attribute <code>attr</code> on the object <code>obj</code> with a Spy.  The object must be defined at the top level (i.e., <code>eval("obj")</code> must return the object).  This is basically the same as:
-
-<pre>
-obj = eval("obj");
-spy = Spy("obj.attr", [applies/options]);
-obj.attr = spy;
-</pre>
-
-</dd>
-
-  <dt><code>Spy.on(obj, "obj.attr", [applies/options])</code></dt>
-  <dd>This is the same as the previous form, except for use when <code>obj</code> is not a global variable.</dd>
-
-  <dt><code>aSpy.formatCall()</code></dt>
-  <dd>When the Spy is called, generally this does:
-
-    <pre>
-print(aSpy.formatCall());
-</pre>
-
-    If you use <code>writes: false</code> then this might be helpful.
-  </dd>
-
-  <dt><code>aSpy.method("methodName", [applies/options])</code></dt>
-  <dd>This creates an attribute <code>aSpy.methodName</code> and assigns a Spy to that attribute.  You may give the normal constructor arguments.</dd>
-
-  <dt><code>aSpy.methods({methodName: [true or options], ...})</code></dt>
-  <dd>This creates multiple attributes at once.  You may use <code>{methodName: true}</code> if you have no options to pass in.</dd>
-
-</dl>
-
-<h4 id="spy-attributes">Spy attributes</h4>
-
-<p>Spies have several attributes to inspect how they have been called:</p>
-
-<dl>
-  <dt><code>aSpy.self</code> and <code>aSpy.selfList</code></dt>
-  <dd>This is the value of <code>this</code> as the spy was called. As the spy is called multiple times each <code>this</code> value is appended to <code>selfList</code>, forming a history.</dd>
-
-  <dt><code>aSpy.args</code> and <code>aSpy.argList</code></dt>
-  <dd>This is the list of arguments that the function was called with. <code>.argList</code> gives the history of past calls.</dd>
-
-</dl>
-
-
-<h3 id="abort">Aborting your tests</h3>
-
-<p>Tests often has prerequesites.  Perhaps some browsers aren't supported.  Maybe you need a server setup.  Normally doctest will run through all the tests regardless of failures, but when basic prerequesites are missing this creates lots of chatter and failures with no purpose.</p>
-
-<p>To stop the tests from running call <code>Abort()</code>.  This will still run the rest of the test block (up until the next <code>// =></code>).</p>
-
-<h3 id="jshint">jshint</h3>
-
-<p>A helper is provided to help you run <a href="http://www.jshint.com/">JSHint</a> regularly on your code. Just do this:</p>
-
-<pre>
-jshint("source-filename.js", [jshint options]);
-</pre>
-
-<p>You can give a full URL, but you can also just give the filename. When given a filename then all the <code>&lt;script></code> tags are searched for that filename.  The source is fetched and JSHint is run on that source.</p>
-
-<p>You may <a href="http://www.jshint.com/docs/">give options to suppress or enforce checks</a>.  In addition you may list the known issues that you wish to ignore: issues are printed out in order, and are matched like any other text.  You might want to use this to simply see the errors without checking them for anything in paticular:
-
-<pre>
-jshint("source-filename");
-// => ...
-</pre>
-
-</p>
-
-<h3 id="nosyxmlhttprequest"><code>NosyXMLHttpRequest</code></h3>
-
-<p>Sometimes you may want to watch the progress of XMLHttpRequest requests &mdash; both how the request is constructed and its result. You can use <code>NosyXMLHttpRequest</code> to wrap request objects.</p>
-
-<p>You probably want to use it like:
-
-<pre>
-XMLHttpRequest = NosyXMLHttpRequest.factory("request");
-</pre>
-</p>
-
-<p>The name will be used when showing output (e.g., <code>request.setRequestHeader('X-Something', 'value')</code>).</p>
-
-
-<h3 id="node">Node.js</h3>
-
-<p>Doctest.js has some Node support.  You must use the <a href="#format-test">comment-based test format</a> in stand-alone Javascript files.  Then:</p>
-
-<pre>
-$ npm install -g doctestjs
-$ doctest test.js
-</pre>
-
-<p>This will print a success or failure message, and will exit with a code (the number of failures) if the test does not pass.</p>
-
-<p>If you do not wish to install the package globally, do:</p>
-
-<pre>
-$ npm install doctestjs
-$ node_modules/.bin/doctest test.js
-</pre>

-
-<p>
-
-So you've decided to finally get religion when it comes to testing your Javascript code?  Or, you feel like testing just isn't as easy as it could be, and want to find a better way to test your Javascript code?  Or even: you've thought about or tried doing Test Driven Development but you've found it hard to get going? Let's do this...
-
-</p>
-
-<p>
-
-Doctest.js is basically <em>example code</em> and then <em>expected output</em>.  This is really what most tests look like, but instead of lots of <code>assertEqual(example, expected)</code> this example/expected combination is embedded into the structure of the test.
-
-</p>
-
-<aside>
-  <h3 id="page-setup">Page Setup</h3>
-
-  <p>
-    See <a href="#html">Setting Up Your HTML</a> to see how to get your test running in the browser.
-  </p>
-</aside>
-
-<p>
-
-I'm going to get right into how the test code looks, but to actually <em>use</em> doctest.js you have to setup an HTML file in a specific format.  That is described later in the <a href="#html">HTML section</a>.
-
-</p>
-
-<p>
-
-The structure looks like something you've probably seen before.  We add one new function, <code>print()</code>, that works a lot like <code>console.log()</code>.  Then we have a comment that shows what we expect to be output.  A really simple example:
-
-    <pre class="test">
-function factorial(n) {
-  if (typeof n != "number") {
-    throw "You must give a number";
-  }
-  if (n <= 0) {
-    return 1;
-  }
-  return n * factorial(n-1);
-}
-
-print(factorial(4))
-// => 25
-    </pre>
-
-</p>
-
-<p>
-
-See what I did there?  25 is totally the wrong answer!  Also see what happened, the test just ran and told us so!  There's also a summary of all the tests; if you do nothing it shows up at the top of the page, but in the interest of introducing the summary, here it is:
-
-</p>
-
-<p id="doctest-output" style="border: 1px solid #999"></p>
-
-<p>
-
-You'll notice it shows a failure (or more than one &mdash; it's the summary for all the examples in this tutorial).  It also has a link to each failure, so you can jump to the problematic section.
-
-</p>
-
-<aside>
-  <h3 id="quoting">Quoting</h3>
-
-  <p>
-    If you are writing your tests inline in the document, remember that you don't need to quote <code>></code> as <code>&amp;gt;</code>, that's only needed for <code>&lt;</code>
-  </p>
-</aside>
-
-<p>
-
-Let's look at what we did there: <code>print(factorial(4))</code> and <code>// => 25</code> &mdash; the output is just a comment that starts with <code>=></code>.
-
-</p>
-
-</section>
-
-<section id="errors">
-  <header>
-    <h3 id="errors">Testing for error conditions</h3>
-  </header>
-
-<p>
-
-You can also test errors:
-
-<pre class="test">
-print(factorial(null));
-// => Error: You must give a number
-</pre>
-
-When an exception is thrown it will print out <code>Error: (error text)</code> which you can match against. This way you can test for error conditions just like you test how "correct" invocations work.  Note that the <code>print()</code> isn't really necessary here, you could do this just as well:
-
-<pre class="test">
-factorial(null);
-// => Error: You must give a number
-</pre>
-
-</p>
-
-</section>
-
-<section id="print">
-  <header>
-    <h3 id="print"><code>print()</code> and output matching</h3>
-  </header>
-
-<aside>
-  <p>For more detail on printing see <a href="reference.html#print">the reference</a>.</p>
-</aside>
-
-<p>
-
-<code>print()</code> pretty-prints things.  This is important, because you have to "expect" the same output that <code>print()</code> produces.  You can give multiple arguments, like with <code>console.log</code>.
-
-<pre class="test">
-print({someProperty: 123, something: {a: 1, b: 2}, "foo": 123.1032, "another-property": [1,2,3,4]});
-/* =>
-{
-  "another-property": [1, 2, 3, 4],
-  foo: 123.1032,
-  someProperty: 123,
-  something: {a: 1, b: 2}
-}
-*/
-</pre>
-
-You might notice that the attributes are alphabetized and are quoted only when necessary.  If it's a small object it stays on one line:
-
-<pre class="test">
-print({someProperty: 123});
-// => {someProperty: 123}
-</pre>
-
-</p>
-
-<p>
-
-But sometimes the output is unpredictable; or rather you can predict it will change.  When that's the case you can basically put a wildcard in the expected output: <code>...</code> &mdash; that will match anything, including multiple lines.  In addition you can use <code>?</code> to match one word-like-thing (a number, symbol, etc; not <code>&quot;</code> or whitespace or other symbols).  You can use it like this:
-
-<pre class="test">
-print({
-  date: new Date(),
-  timestamp: Date.now()
-});
-
-// => {date: ..., timestamp: ?}
-</pre>
-
-</p>
-
-<p>
-
-You might notice that it <em>passes</em>, but you still get to see the actual output.  This is a great way to show information that you can review, without actually testing.  For instance, you might be testing something that connects to a server, in that case you might want to do this:
-
-<pre class="test">
-var server = {url: "http://localhost:8000"} // or some calculated value
-print(server.url);
-// => ...
-</pre>
-
-Now if everything seems breaky you can be 100% sure of what server you are connecting to.
-
-</p>
-
-<p>
-
-If you have a variable that is dynamic but you still care about the value, you should do something like this:
-
-<pre class="test">
-var date = Date.now();
-print(date == date, date);
-// => true ...
-</pre>
-
-Think of this pattern of <code>print(x == y)</code> as a kind of <code>assertEqual()</code> equivalent.

-    <h3 id="async">Testing async code</h3>

-</aside>
-
-<p>
-
-This is all well and good, but lots of code in Javascript is <em>asynchronous</em>, meaning that you don't just call a function that returns a value.  Doctest.js has an answer to that too: a great answer!
-
-</p>
-
-<p>
-
-For our example we'll use <code>XMLHttpRequest</code>, a common source of asynchronosity.  We'll test a request (just a loopback request, but if you are testing a foreign service you'd need <a href="http://enable-cors.org/">CORS access</a>).  When we instantiate and setup the request we don't have anything really to test &mdash; we want to test what happens when the request <em>completes</em>.
-
-</p>
-
-<p>
-
-To do this we'll use <code>wait()</code> &mdash; when this function is called the test runner will wait at the point where it sees <code>// =></code>, for a certain amount of time or until a certain condition is met. Only then will it compare all the output that has happened to what was expected, and run the next chunk of test.
-
-</p>
-
-<p>
-
-You can use this like: <code>wait(function () {return true when done})</code> or <code>wait(millisecondsToWait)</code>.  We'll use the first form, which is almost always better, since it allows the test to continue more quickly.  Tests also always time out eventually (by default the timeout is 5000 milliseconds, i.e., 5 seconds &mdash; by convention everything in Javascript is in milliseconds).
-
-<pre class="test">
-var endpoint = location.href;
-print(endpoint);
-// => ...
-
-var req = new XMLHttpRequest();
-req.open("GET", endpoint);
-req.onreadystatechange = function () {
-  if (req.readyState != 4) {
-    // hasn't actually finished
-    return;
-  }
-  print("Result:", req.status, req.getResponseHeader('content-type'));
-};
-req.send();
-
-wait(function () {return req.readyState == 4;});
-
-print("Current state:", req.readyState);
-
-/* =>
-Current state: 1
-Result: 200 text/html
-*/
-</pre>
-
-I put in something tricky there to try to clarify what <code>wait()</code> really does.  You'll notice there's a call to <code>wait()</code> that makes sure that <code>req.readyState == 4</code> (that's the code that means the request is finished).  But right after when we do <code>print(req.readyState)</code> it shows a readyState of 1.  That's because the <em>entire</em> block is printed (from the previous <code>// =></code> output up until the next one).  But the test runner keeps collecting output and doesn't run the next section until that <code>wait()</code> clause returns true.
-
-</p>
-
-<p>
-
-Another thing to note is that <code>wait()</code> needs to be called when that block of code is run &mdash; it can't be inside a function that isn't called.  That said, if you write test helper functions (and you should!), it often works well to put those calls in the helper function.  We'll see an example of that next...

-
-Note: the next example will use some jQuery, just for the heck of it, though there is no special support for jQuery or other frameworks in Doctest.
-
-</p>
-
-<p>
-
-If you use these tools you might end up writing code like this quite a lot:
-
-<pre class="test">
-// We've embedded a button just below this element
-var button = $('#example-button');
-// Just to highlight what we're working with:
-button.css({border: '1px dotted #f00'});
-button.click(function () {
-  print('Button clicked');
-});
-
-// Now we test that our event handler gets called when we do an artificial click of the button:
-button.click();
-// => Button clicked
-</pre>
-
-<button id="example-button" type="button">Example Button</button>
-
-</p>
-
-<p>
-
-But maybe we are curious about the arguments passed to that handler &mdash; even though we ignored the arguments, there was one passed.  And we might want to show what <code>this</code> is bound to; <code>this</code> is kind of like an invisible extra argument passed to every function invocation.  We could make a fancier <code>print()</code> statement there.  But instead, there's also a handy tool for tracking calls: <code>Spy</code>.
-
-</p>
-
-<p>
-
-An example:
-
-<pre class="test">
-var button = $('#example-button2');
-button.css({border: '1px dotted #00f'});
-button.click(Spy('button.click'));
-button.click();
-
-// => ...
-</pre>
-
-<button id="example-button2" type="button">Example Button 2</button>
-
-</p>
-
-<p>
-
-That's a lot more information!  Let's break it down:
-
-<pre>
-<b style="color: #00a">&lt;button id="example-button2" style="border: 1px solid rgb(0, 0, 255); " type="button">Example Button 2&lt;/button>.</b><span style="color: #0a0">button.click</span>({ ...
-</pre>
-
-There's two bits of information here.  The first is the value (in <span style="color: #00a">blue</span>) of <code>this</code>, which is the <code>#example-button2</code> element.  You'll notice it shows the HTML of the element.  If you want Spy to ignore this you can use <code>Spy('button.click', {ignoreThis: true})</code>.
-
-</p>
-
-<p>
-
-The second value (in <span style="color: #0a0">green</span>) is the name we gave the Spy when we created it. Note that Spy names are also identifiers, that is, <code>Spy('button.click') === Spy('button.click')</code>.
-
-</p>
-
-<p>
-
-Next of course is all the arguments.  There's a lot of arguments there.  They are... interesting.  You'll notice some references to <code>...recursive...</code> which is what you get when you have self-referencing data structures.  But maybe you want to test just a little of that structure without testing all of it.  You might do something like this:
-
-<pre class="test">
-// Spy('button.click') fetches the same Spy we were using before, which still has all its call information
-// .formatCall() shows the way the Spy was last called.
-print(Spy('button.click').formatCall());
-
-/* =>
-&lt;button...&lt;/button>.button.click({
-  currentTarget: &lt;button...
-  ...
-  timeStamp: ?,
-  type: "click"
-})
-*/
-
-</pre>
-
-So we've tested that the <code>type</code> is click, that it has a timeStamp (though not the value) and that the <code>currentTarget</code> is a button (presumably the button we bound it to).  We still get to <em>see</em> all the other information, we just aren't <em>testing</em> it.  This can be helpful in the future when you realize there's more you want to test &mdash; you can look at the test output and transcribe more into the test.  Or when something fails later you might want to inspect that output to make sure everything is what you expect (and when you see something unexpected that's also a great time to expand your test).
-
-</p>
-
-<p>
-
-Spies have a bunch of options, and act as a kind of mock object as well.  You can pass in options as the second argument, like <code>Spy('name', {options...})</code>.  Some highlights:
-
-
-<dl>
-  <dt><code>applies</code></dt>
-  <dd>This is a function that the Spy "wraps".  So if you do <code>Spy('click', {applies: function (event) {this.remove(); return false;}})</code> then you'll get the same output printed, but you'll also run <code>this.remove()</code>.</dd>
-
-  <dt><code>writes</code></dt>
-  <dd>If you set this to <code>false</code> then it won't automatically print out the calls.  The values of the calls will still be recorded, and you can use <code>aSpy.formatCall()</code> to see them.</dd>
-
-  <dt><code>ignoreThis</code></dt>
-  <dd><p>Lots of code binds <code>this</code> without intending too.  It's really easy in Javascript to do this.  For instance, if you do <code>handlers[i]()</code> then <code>this</code> will be <code>handlers</code>.  (Instead you might do <code>var handler = handlers[i]; handler()</code>)</p>
-
-    <p>Anyway, sometimes you don't care about <code>this</code>, and using <code>{ignoreThis: true}</code> lets you do that.
-  </p></dd>
-
-  <dt><code>returns</code></dt>
-  <dd>If you want the Spy to return a value when its called, give the value here.  Normally it returns <code>undefined</code>.</dd>
-
-  <dt><code>throwError</code></dt>
-  <dd>This makes the Spy throw the given error anytime it is called.</dd>
-
-  <dt><code>wait</code></dt>
-  <dd>If you use <code>Spy('name', {wait: true})</code> then the test will wait until the Spy has been called. This is a pretty common pattern.  It's basically the same as <code>Spy('name').wait()</code>.</dd>
-
-</dl>
-
-</p>
-
-<p>
-
-You can set values like <code>Spy.defaultOptions.writes = false</code> if you want to set one of these by default.
-
-</p>
-
-<p>
-
-If you want to inspect how the Spy has been called, you can check a few attributes:
-
-<dl>
-
-  <dt><code>.called</code></dt>
-  <dd>True once this Spy has been called.</dd>
-
-  <dt><code>.self</code> and <code>.selfList</code></dt>
-  <dd>This is the value of <code>this</code>, or <code>.selfList</code> contains a history for each call.</dd>
-
-  <dt><code>.args</code> and <code>.argList</code></dt>
-  <dd>The arguments the function was called with, or <code>.argList</code> is a history of arguments.</dd>
-
-</dl>

-

-
-<p>
-
-When you use <code>console.log</code> (or any of its friends, like <code>console.warn</code>) those messages will be captured (in addition to going to the log as normal), and the output will be shown in the specific test where they happened.  A quick example:
-
-<pre class="test">
-function enumProps(object) {
-  console.log('obj', object);
-  var result = {}
-  for (var attr in object) {
-    if (typeof object[attr] == "number" && attr.toUpperCase() == attr) {
-      result[object[attr]] = attr;
-    }
-  }
-  return result;
-}
-
-print(enumProps($('#example-button')[0]));
-
-// => {...}
-

-
-You can think of it a little like <code>print()</code> goes to stdout, and <code>console.log()</code> goes to stderr.

-Tests often require some feature or setup to be usable at all.  When it's not setup right you'll just get a bunch of meaningless failures.  For this reason there's a way to abort all your tests.  If you call <code>Abort()</code> then no further tests will be run.  If you want to connect to a server, for instance, you might check that the server is really there, and if not then just abort the rest of the tests.  For example:
-
-<pre>
-$.ajax({
-  url: '/ping',
-  success: Spy('ping', {wait: true, ignoreThis: true}),
-  error: function () {
-    Abort("Server isn't up");
-  }
-});
-
-// => ping(...)

-
-I wanted to show you all the cool features of doctest first, but you can't actually use any of them unless you set up a test runner page.  Luckily the page is pretty simple.  Let's say you've put doctest.js into <code>doctest/</code>:
-
-<pre>
-&lt;DOCTYPE html>
-&lt;html>
-  &lt;head>
-    &lt;meta charset="UTF-8">
-    &lt;title>My Test&lt;/title>
-    &lt;script src="doctest/doctest.js">&lt;/script>
-    &lt;link href="doctest/doctest.css" rel="stylesheet">
-    <b>&lt;script src="mylibrary.js">&lt;/script></b>
-  &lt;/head>
-  &lt;body class="autodoctest">
-
-  A test:
-
-&lt;pre class="test">
-test goes here
-&lt;/pre>
-
-  &lt;/body>&lt;/html>
-</pre>
-
-</p>
-
-<p>
-
-Mostly it's just boilerplate: you have to include <code>doctest.js</code> and <code>doctest.css</code> and of course any libraries or dependencies of the thing you are testing.  You also must use <b><code>&lt;body class="autodoctest"></code></b> &mdash; that's what tells doctest.js you want to find and run tests right away.
-
-</p>
-
-<p>
-
-Each test then is in a <code>&lt;pre class="test"></code>.  You might not want to actully write your tests <em>inside</em> the HTML, and instead put them in a separate Javascript file.  To do that use:
-
-<pre>
-&lt;pre class="test" href="./my_tests.js">&lt;/pre>
-</pre>
-
-This will load the test code from <code>./my_tests.js</code> and inline it into the element.  This is how I personally write most of my tests, though when moving between a narrative and tests (as I am doing in this tutorial) it is nice to keep the tests together with the descriptions.
-
-</p>
-
-<p>
-
-Note that specifically when you use <code>href="URL.js"</code> you can split the tests into sections by including the comment <code><b>// == SECTION</b> Your Section Header Name</code> in the included file, and you'll get multiple elements with headers automatically.
-
-</p>
-
-<p>
-
-A pass/fail summary is automatically added to the top of the page, though you can use <code>&lt;div id="doctest-output">&lt;/div></code> to position it someplace specific (as we did in this tutorial).
