Doctest.js: examples

-
-

-
-

-
-
Web Service

-
-

-  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.
-

-
-

-  In this example we'll access the Geonames
-  API.  First we'll want some routines to help us later on.  You
-  could put these into a separate .js 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...
-
-
-$ 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')
->   });
-> }
-

-
-  Some things to notice about this example:
-
-  
    
-    
  • apiLocation is hard coded, but you could read it
-    from the query string, allowing something like
-    test.html?apiLocation=http://localhost:8080.
-    
    • 
-
-    
  • 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 .called.
-    If you used {writes: true} you might not need the
-    .applies functions.
-    
    • 
-
-    
  • wait 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 writeln()).  Timeout is the other
-    possibility.
-    
    • 
-  

-
-

-
-

-  Now we'll use the routine to actually run a test:
-
-
-$ query('postalCodeSearchJSON', {postalcode: 9011, maxRows: 5});
-success({
-  postalCodes: [
-    {...}
-  ]
-}, ...)
-

-
-

-
-
Web Service/XML

-
-

-  What we do for JSON, we can also do for XML; in this case
-  it's just fetching a static XML Atom document.
-
-
-$.ajax({
-  url: './.resources/example.xml',
-  dataType: 'xml',
-  success: function (doc) {
-    gdoc = doc;
-    writeln(repr(doc));
-  },
-  error: Spy('error')
-});
-wait(0.5);
-/* =>
-<feed xmlns="http://www.w3.org/2005/Atom">
-  <title>Example Feed</title>
-  ...
-</feed>
-*/
-
-

-
-

-
-
Deferred/Promise

-
-

-
-  You can also
-  print jquery.Deferred
-  (promise) objects once they've resolved, using
-  the printResolved() function.  This also implicitly
-  calls wait() with the condition that all the promises
-  be resolved.  Both errors and resolved values are printed.
-
-  
-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

-    Doctest.js: the humane Javascript test framework

Doctest.js: A Humane Javascript Test Framework

-
-        
-
-      

-    

-
-    

-      

-
-
-     
-
-
-
Doctest.js is a test runner and testing framework for Javascript.

-
-
Doctest uses a novel approach to testing: example and expected result.  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.

-
-
An example (note: these are live examples — you can also try your own via the live demo):
-
-
-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
-

-

-
-
This is similar to something like assertEqual(capitalize('some words'), 'Some Words') — 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 — 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:
-
-
-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"));
-// =>
-

-
-

-
-
Look: the first example worked great, ["a", "b"].  The second example though wasn't right at all.  "0"?  Once we have a better idea we can adjust those tests:
-
-
-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"));
-// => []
-

-
-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 presence and absence. Most test frameworks only give you tools to test what is there, and not ensure that the things you don't want aren't there.

-
-
Async testing made easy!

-
-
The other great feature of doctest.js is how it lets you test async code.

-
-
Async code is a bit tricky for all test runners.  When you run the test, the result 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 make sure that some callback was called — it's relatively easier to test that the callback was called correctly.

-
-
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.

-
-
The core feature here is wait() — this lets you register a callback that will tell the test runner when this block of code is fully finished.  An example:
-
-
-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! ...
-

-
-(Notice we use ... to ignore the specific number that is printed: ellipsis act as a kind of wildcard)
-
-

-
-
With Doctest you don't have to use fake setTimeout or fake async anywhere — 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.

-
-
Mocking with Spy

-
-
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 — 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:
-
-
-var button = $('<button></button>');
-$('body').append(button);
-button.click(Spy('button.click'));
-button.click();
-Spy('button.click').wait();
-/* =>
-<button />.button.click({...})
-*/
-

-
-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 this is shown: people usually forget that this is a kind of implicit argument to many functions, but again doctest makes the implicit explicit.  Also note that the actual 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.
-

-
-
-
Lineage

-
-
Doctest is based on the Python doctest module originally written by Tim Peters.  Spy was inspired some by Jasmine's Spy class, and carries over ideas from MiniMock.

-
-
If you've used Python's doctest and found it annoying or not widely useful for doctest: doctest.js fixes all those problems: see this post for more.

HTML page

-
-
Your HTML page needs just a couple things to set it up for a test:
-
-
-<html>
- <head>
-  <script src="doctestjs/doctest.js"></script>
-  <link href="doctestjs/doctest.css" rel="stylesheet">
- </head>
- <body class="autodoctest">
-
-  <pre class="test / doctest">
-    test
-  </pre>
- </body>
-</html>
-

-
-

-
-
Notably you need <body class="autodoctest"> to get the tests to run automatically on page load.  If you were invoking doctest explicitly (like is done on the Try It page) then you might leave this off.

-
-
External code

-
-
Often you won't want to write your test code inside the test itself.  Instead you'll want to put it in its own .js file.  Especially with test the code is valid Javascript, and you will probably want syntax highlighting and all that.

-
-
To do this, use an href attribtue on your <pre> element, like:
-
-
-<pre class="test" href="./tests.js"></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 cross-origin errors if you tried that — this doesn't use <script> tags to load those scripts, it uses XMLHttpRequest).  Note that the class is still required!

-
-
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 class="test" data-href-pattern="./{test-name|default.js}"></pre>
-

-
-Any URL parameters (like {test-name}) get filled in by the query string (?test-name=example.js).  By default these values can only contain letters, numbers, _, - and . — this is to protect against loading scripts from unexpected locations via an implicitly unsafe parameters in the query string.

-
-
If you want to use a different restriction on a variable name, use {variable-name:regular_expression} — and use ^ and $ to make sure to match the entire string.

-
-
If you want a default (if the parameter isn't set or is empty) use | to separate out the default.  The default should come after the regular expression.  In the example the default is default.js.  Don't use extra spaces around |!

-
-
Note this works well with relative addresses like <a href="?test-name=foo.js">foo.js</a>

-
-
Format of test

-
-
There are two formats that a doctest can take.  You've probably seen the test format, there is also the more traditional doctest format.

-
-
doctest format

-
-
This format is used like:
-
-
-<pre class="doctest">
-$ first_line();
-> continuation line
-output
-</pre>
-

-
-

-
-
The first line of course starts wtih $ and a space. Think of it like a Unix command line.  And also similar to a command line shell the continuation line is >.  Any line without a leading $ or > is considered expected output.

-
-
Note you can still have multiple statements using a continuation line.  The only difference between two lines with $ and one with a $ followed by > is that in the latter case the two lines are executed together and the output from both is combined into what is expected.

-
-
test format

-
-
In this format the expected output is in a comment, like:
-
-
-<pre class="test">
-statement_1();
-statement_2();
-// Some other comment
-// => expected output
-
-More statements
-
-/* =>
-expected output
-*/
-

-
-

-
-
Basically the test is split up by using the // => comments.  Each chunk is executed independently, and the test may be paused at the point where the expected output is found.

-
-
Test sections

-
-
If you are using external test code (and test) you can include section headers like:
-
-
-// == SECTION A section header
-

-
-

-
-
You can have one or more ='s.  The text A section header will become a header.  Each section header turns into a new <pre> element.

-
-
Compact <pre>'s

-
-
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 class="test expand-on-failure">
-  ...
-</pre>
-

-
-This will make the test 3em tall unless there's a failure, at which point it expands to its full size.

-
-
Printing/writing

-
-
The print() function is pretty important, of course. (Note it also was called writeln(), a name which is still supported).

-
-
print() will print out any strings given to it, and the repr() of any other objects, with a space between each argument.

-
-
You can make a custom repr() for any object by adding a .repr() method.  It should look like:
-
-
-MyObject.prototype.repr = function () {
-  return '[MyObject attr: ' + repr(this.attr) + ']';
-};
-

-
-

-
-
If you can't add a method to your object, you can also add a stringifier using repr.register().

-
-
You might do this like:
-
-
-repr.register(
-  function (o) {
-    return o instanceof MyClass;
-  },
-  function (o, indentString) {
-    return '[MyClass attr: ' + repr(o.attr) + ']';
-  }
-);
-

-
-The first function is a test that is applied to objects.  If it returns true, then the second function is called to stringify the object.  If your representation uses multiple lines, then you should indent subsequent lines with the string, like return '[Beginning\n' + indentString + '  end\n' + indentString + ']';.  The beginning is never indented.
-
-

-
-
Some of the objects that have custom representations:

-
-

-  
XML and DOM objects

-  
These are displayed as the normal serialization, e.g., <input type="text" />.  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.

-
-  
XMLHttpRequest

-  
These are displayed like [XMLHttpRequest STATE [STATUS]].  The STATE is one of UNSENT, OPENED, HEADERS_RECEIVED, LOADING and DONE.  The [STATUS] is only displayed if the request has finished.

-
-

-
-
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 print(o.constructor) if you want to be specific about classes.

-
-
console.log()

-
-
console.log() works a lot like print(). But unlike print() it doesn't make a test pass or fail, it's purely informative.

-
-
All the methods on console should work, like console.warn().  The underlying normal console function is called, but in addition on a test-by-test basis these are collected and displayed.

-
-
printResolved() for Deferred and Promises

-
-
There's special support for the jQuery Deferred object, and generally Promises/A.

-
-
This support is through the printResolved() function, which is basically equivalent to print() except any promise arguments will be waited on to resolve (proper resolution or an error).  You can use it like this:

-
-
-var def = $.Deferred();
-setTimeout(function () {
-  def.resolve("Resolved!");
-});
-printResolved(def);
-// => Resolved!
-

-
-
Errors are printed out with Error: before the value, and multiple arguments are printed out with spaces between them, or a placeholder if there's no arguments.  For instance:

-
-
-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)
-

-
-
Output matching

-
-
The expected output is compared with the output you actually got (received).

-
-
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.

-
-
There are two wildcard patterns.  Ellipsis — ... — means "match anything".  This will match zero character, or multiple lines.  You should be careful about matching too much.

-
-
The shorter wildcard is ?.  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 "?".

-
-
Also a special case, " matches ' and vice versa.  Since in most contexts these mean the same thing, this lets you be agnostic.

-
-
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.

-
-
wait(), async code, and pausing the tests

-
-
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.

-
-
Each section of code can be paused at the end. Code cannot be paused in the middle of a section.  So before the output (i.e., before // =>) the test runner can wait and collect output.

-
-
Anytime you call wait() inside a section of code it tells the test runner to wait at the end of the test, either until some condition is true or until some time has passed.  If the condition doesn't complete an error/timeout message is print()'d.

-
-
A half baked version of what happens is this:
-
-
-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);
-}
-

-
-Now you practically know how to write doctest yourself!
-

-
-
Specifically this is how you can run wait():

-
-

-  
wait()

-  
This makes the test pause just for a moment.  It's the same as wait(0).

-
-  
wait(milliseconds)

-  
This forces the test to pause for the given number of milliseconds.  Everything is always in milliseconds.

-
-  
wait(condition)

-  
This calls condition() frequently until it returns true.

-
-  
wait(condition, timeout)

-  
This calls condition up until timeout milliseconds. You can use this to extend the timeout.  The default timeout is 5 seconds (5000).

-

-
-
Spy, mocking, and watching functions

-
-
Spy is used to create a mock object/function that can be used to track calls and inspect call order and arguments.

-
-
The basic use is like this:
-
-
-func = Spy('func');
-func(1, 2, 3);
-
-obj = {a: 1, func: func};
-obj.func();
-
-/* =>
-func(1, 2, 3)
-{a: 1, func: Spy('func')}.func()
-*/
-

-
-

-
-
That is, every time the Spy is called it will print out the call, all its arguments, and if there was a bound this (as in the obj.func() example) then that value will be displayed as well.

-
-
Each spy is named, and if you call Spy(name) with a name that has been used before you will get the same Spy object back.

-
-
Spy can be invoked in a couple ways:

-
-

-  
Spy(name)

-  
Just creates/gets the Spy with the given name.

-
-  
Spy(name, {options})

-  
Create the Spy with some options (as described below)

-
-  
Spy(name, function () {...})

-  
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 this.

-
-  
Spy(name, function () {...}, {options})

-  
Create a Spy that wraps a function and has extra options.

-
-

-
-
Note that your function can raise an exception, and the Spy will pass it through (though also note the exception using console.log()).  You can use this to inspect how a library reacts to exceptions in callbacks.

-
-
Spy options

-
-
The options available:

-
-

-  
applies: function () {...}

-  
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.

-
-  
writes: false (default true)

-  
If this is false (default true) then it will not print out the call.

-
-  
returns: value (default undefined)

-  
This is what the Spy returns when called (assuming you did not use applies).  By default it simply returns undefined, which is what a function returns when you have no explicit return statement.

-
-  
throwError: exceptionObject

-  
If given, when the Spy is called it'll do throw exceptionObject

-
-  
ignoreThis: true (default false)

-  
If true, then this won't be printed out regardless of whether it is bound.  This is useful when a library binds this carelessly.

-
-  
wrapArgs: true (default false)

-  
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).

-
-  
wait: true (default false)

-  
This is equivalent to calling Spy(name).wait(). You can also pass in a number, which will be the millisecond timeout, e.g., Spy(name, {wait: 10000}) to wait for 10 seconds for the Spy to be called.

-
-  
methods: {...}

-  
Equivalent to calling Spy.methods({...}).  See below for details.

-
-

-
-
You can also change Spy.defaultOptions if you want to override one option by default, for instance to turn off printing or ignore this.

-
-
Spy methods

-
-
Several methods are available:

-
-

-  
Spy().wait([timeout])

-  
This makes the test pause until the Spy has been called. Sometimes you must use the method instead of Spy(name, {wait: true}).  An example:
-
-    
-SomeAPI.onload = Spy('SomeAPI.onload', function (data) {
-  SomeOtherAPI.save(data, Spy('SomeOtherAPI.save'));
-};
-Spy('SomeOtherAPI.save').wait();
-/* =>
-SomeAPI.onlaod({...})
-SomeOtherAPI.save()
-*/
-

-
-    In this case the Spy is created inside another method, and that method is not called right away.  wait: true doesn't work in this case.  Instead you should call Spy(name).wait() later.  Since names are unique, this will be the same Spy object as referenced earlier.
-

-
-  
Spy.on("obj.attr", [applies/options])

-  
This replaces the attribute attr on the object obj with a Spy.  The object must be defined at the top level (i.e., eval("obj") must return the object).  This is basically the same as:
-
-
-obj = eval("obj");
-spy = Spy("obj.attr", [applies/options]);
-obj.attr = spy;
-

-
-

-
-  
Spy.on(obj, "obj.attr", [applies/options])

-  
This is the same as the previous form, except for use when obj is not a global variable.

-
-  
aSpy.formatCall()

-  
When the Spy is called, generally this does:
-
-    
-print(aSpy.formatCall());
-

-
-    If you use writes: false then this might be helpful.
-  

-
-  
aSpy.method("methodName", [applies/options])

-  
This creates an attribute aSpy.methodName and assigns a Spy to that attribute.  You may give the normal constructor arguments.

-
-  
aSpy.methods({methodName: [true or options], ...})

-  
This creates multiple attributes at once.  You may use {methodName: true} if you have no options to pass in.

-
-

-
-
Spy attributes

-
-
Spies have several attributes to inspect how they have been called:

-
-

-  
aSpy.self and aSpy.selfList

-  
This is the value of this as the spy was called. As the spy is called multiple times each this value is appended to selfList, forming a history.

-
-  
aSpy.args and aSpy.argList

-  
This is the list of arguments that the function was called with. .argList gives the history of past calls.

-
-

-
-
-
Aborting your tests

-
-
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.

-
-
To stop the tests from running call Abort().  This will still run the rest of the test block (up until the next // =>).

-
-
jshint

-
-
A helper is provided to help you run JSHint regularly on your code. Just do this:

-
-
-jshint("source-filename.js", [jshint options]);
-

-
-
You can give a full URL, but you can also just give the filename. When given a filename then all the <script> tags are searched for that filename.  The source is fetched and JSHint is run on that source.

-
-
You may give options to suppress or enforce checks.  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:
-
-
-jshint("source-filename");
-// => ...
-

-
-

-
-
NosyXMLHttpRequest

-
-
Sometimes you may want to watch the progress of XMLHttpRequest requests — both how the request is constructed and its result. You can use NosyXMLHttpRequest to wrap request objects.

-
-
You probably want to use it like:
-
-
-XMLHttpRequest = NosyXMLHttpRequest.factory("request");
-

-

-
-
The name will be used when showing output (e.g., request.setRequestHeader('X-Something', 'value')).

-
-
-
Node.js

-
-
Doctest.js has some Node support.  You must use the comment-based test format in stand-alone Javascript files.  Then:

-
-
-$ npm install -g doctestjs
-$ doctest test.js
-

-
-
This will print a success or failure message, and will exit with a code (the number of failures) if the test does not pass.

-
-
If you do not wish to install the package globally, do:

-
-
-$ npm install doctestjs
-$ node_modules/.bin/doctest test.js
-

-
-

Doctest.js: A Tutorial 

-
-        
-
-      

-    

-
-    

-      

-
-
-     
-
-
-
-
-

-
-          

-            

-              

-                
What's it like?

-              

-
-

-
-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...
-
-

-
-

-
-Doctest.js is basically example code and then expected output.  This is really what most tests look like, but instead of lots of assertEqual(example, expected) this example/expected combination is embedded into the structure of the test.
-
-

-
-
-
-

-
-I'm going to get right into how the test code looks, but to actually use doctest.js you have to setup an HTML file in a specific format.  That is described later in the HTML section.
-
-

-
-

-
-The structure looks like something you've probably seen before.  We add one new function, print(), that works a lot like console.log().  Then we have a comment that shows what we expect to be output.  A really simple example:
-
-    
-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
-    

-
-

-
-

-
-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:
-
-

-
-

-
-

-
-You'll notice it shows a failure (or more than one — 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.
-
-

-
-
-
-

-
-Let's look at what we did there: print(factorial(4)) and // => 25 — the output is just a comment that starts with =>.
-
-

-
-

-
-

-  

-    
Testing for error conditions

-  

-
-

-
-You can also test errors:
-
-
-print(factorial(null));
-// => Error: You must give a number
-

-
-When an exception is thrown it will print out Error: (error text) which you can match against. This way you can test for error conditions just like you test how "correct" invocations work.  Note that the print() isn't really necessary here, you could do this just as well:
-
-
-factorial(null);
-// => Error: You must give a number
-

-
-

-
-

-
-

-  

-    
print() and output matching

-  

-
-
-
-

-
-print() pretty-prints things.  This is important, because you have to "expect" the same output that print() produces.  You can give multiple arguments, like with console.log.
-
-
-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}
-}
-*/
-

-
-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:
-
-
-print({someProperty: 123});
-// => {someProperty: 123}
-

-
-

-
-

-
-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: ... — that will match anything, including multiple lines.  In addition you can use ? to match one word-like-thing (a number, symbol, etc; not " or whitespace or other symbols).  You can use it like this:
-
-
-print({
-  date: new Date(),
-  timestamp: Date.now()
-});
-
-// => {date: ..., timestamp: ?}
-

-
-

-
-

-
-You might notice that it passes, 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:
-
-
-var server = {url: "http://localhost:8000"} // or some calculated value
-print(server.url);
-// => ...
-

-
-Now if everything seems breaky you can be 100% sure of what server you are connecting to.
-
-

-
-

-
-If you have a variable that is dynamic but you still care about the value, you should do something like this:
-
-
-var date = Date.now();
-print(date == date, date);
-// => true ...

-Think of this pattern of print(x == y) as a kind of assertEqual() equivalent.

Testing async code

-  

-
-
-
-

-
-This is all well and good, but lots of code in Javascript is asynchronous, meaning that you don't just call a function that returns a value.  Doctest.js has an answer to that too: a great answer!
-
-

-
-

-
-For our example we'll use XMLHttpRequest, 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 CORS access).  When we instantiate and setup the request we don't have anything really to test — we want to test what happens when the request completes.
-
-

-
-

-
-To do this we'll use wait() — when this function is called the test runner will wait at the point where it sees // =>, 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.
-
-

-
-

-
-You can use this like: wait(function () {return true when done}) or wait(millisecondsToWait).  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 — by convention everything in Javascript is in milliseconds).
-
-
-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
-*/
-

-
-I put in something tricky there to try to clarify what wait() really does.  You'll notice there's a call to wait() that makes sure that req.readyState == 4 (that's the code that means the request is finished).  But right after when we do print(req.readyState) it shows a readyState of 1.  That's because the entire block is printed (from the previous // => output up until the next one).  But the test runner keeps collecting output and doesn't run the next section until that wait() clause returns true.
-
-

-
-

-
-Another thing to note is that wait() needs to be called when that block of code is run — 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...

The Spy

-  

-
-
-
-

-
-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.
-
-

-
-

-
-If you use these tools you might end up writing code like this quite a lot:
-
-
-// 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
-

-
-
-
-

-
-

-
-But maybe we are curious about the arguments passed to that handler — even though we ignored the arguments, there was one passed.  And we might want to show what this is bound to; this is kind of like an invisible extra argument passed to every function invocation.  We could make a fancier print() statement there.  But instead, there's also a handy tool for tracking calls: Spy.
-
-

-
-

-
-An example:
-
-
-var button = $('#example-button2');
-button.css({border: '1px dotted #00f'});
-button.click(Spy('button.click'));
-button.click();
-
-// => ...
-

-
-
-
-

-
-

-
-That's a lot more information!  Let's break it down:
-
-
-<button id="example-button2" style="border: 1px solid rgb(0, 0, 255); " type="button">Example Button 2</button>.button.click({ ...
-

-
-There's two bits of information here.  The first is the value (in blue) of this, which is the #example-button2 element.  You'll notice it shows the HTML of the element.  If you want Spy to ignore this you can use Spy('button.click', {ignoreThis: true}).
-
-

-
-

-
-The second value (in green) is the name we gave the Spy when we created it. Note that Spy names are also identifiers, that is, Spy('button.click') === Spy('button.click').
-
-

-
-

-
-Next of course is all the arguments.  There's a lot of arguments there.  They are... interesting.  You'll notice some references to ...recursive... 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:
-
-
-// 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());
-
-/* =>
-<button...</button>.button.click({
-  currentTarget: <button...
-  ...
-  timeStamp: ?,
-  type: "click"
-})
-*/
-
-

-
-So we've tested that the type is click, that it has a timeStamp (though not the value) and that the currentTarget is a button (presumably the button we bound it to).  We still get to see all the other information, we just aren't testing it.  This can be helpful in the future when you realize there's more you want to test — 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).
-
-

-
-

-
-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 Spy('name', {options...}).  Some highlights:
-
-
-

-  
applies

-  
This is a function that the Spy "wraps".  So if you do Spy('click', {applies: function (event) {this.remove(); return false;}}) then you'll get the same output printed, but you'll also run this.remove().

-
-  
writes

-  
If you set this to false then it won't automatically print out the calls.  The values of the calls will still be recorded, and you can use aSpy.formatCall() to see them.

-
-  
ignoreThis

-  
Lots of code binds this without intending too.  It's really easy in Javascript to do this.  For instance, if you do handlers[i]() then this will be handlers.  (Instead you might do var handler = handlers[i]; handler())

-
-    
Anyway, sometimes you don't care about this, and using {ignoreThis: true} lets you do that.
-  

-
-  
returns

-  
If you want the Spy to return a value when its called, give the value here.  Normally it returns undefined.

-
-  
throwError

-  
This makes the Spy throw the given error anytime it is called.

-
-  
wait

-  
If you use Spy('name', {wait: true}) then the test will wait until the Spy has been called. This is a pretty common pattern.  It's basically the same as Spy('name').wait().

-
-

-
-

-
-

-
-You can set values like Spy.defaultOptions.writes = false if you want to set one of these by default.
-
-

-
-

-
-If you want to inspect how the Spy has been called, you can check a few attributes:
-
-

-
-  
.called

-  
True once this Spy has been called.

-
-  
.self and .selfList

-  
This is the value of this, or .selfList contains a history for each call.

-
-  
.args and .argList

-  
The arguments the function was called with, or .argList is a history of arguments.

-
-

-
-

-
-

-
-

-  

-    
console.log

-  

-
-

-
-This isn't a feature you have to do anything about, it's just there for you, so I'm just going to point it out.
-
-

-
-

-
-When you use console.log (or any of its friends, like console.warn) 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:
-
-
-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 print() goes to stdout, and console.log() goes to stderr.
-
-

-
-

-
-

-  

-    
Giving Up

-  

-
-

-
-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 Abort() 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:
-
-
-$.ajax({
-  url: '/ping',
-  success: Spy('ping', {wait: true, ignoreThis: true}),
-  error: function () {
-    Abort("Server isn't up");
-  }
-});
-
-// => ping(...)
-

-
-

-
-

-
-

-  

-    
Setting Up Your HTML

-  

-
-
-
-

-
-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 doctest/:
-
-
-<DOCTYPE html>
-<html>
-  <head>
-    <meta charset="UTF-8">
-    <title>My Test</title>
-    <script src="doctest/doctest.js"></script>
-    <link href="doctest/doctest.css" rel="stylesheet">
-    <script src="mylibrary.js"></script>
-  </head>
-  <body class="autodoctest">
-
-  A test:
-
-<pre class="test">
-test goes here
-</pre>
-
-  </body></html>
-

-
-

-
-

-
-Mostly it's just boilerplate: you have to include doctest.js and doctest.css and of course any libraries or dependencies of the thing you are testing.  You also must use <body class="autodoctest"> — that's what tells doctest.js you want to find and run tests right away.
-
-

-
-

-
-Each test then is in a <pre class="test">.  You might not want to actully write your tests inside the HTML, and instead put them in a separate Javascript file.  To do that use:
-
-
-<pre class="test" href="./my_tests.js"></pre>
-

-
-This will load the test code from ./my_tests.js 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.
-
-

-
-

-
-Note that specifically when you use href="URL.js" you can split the tests into sections by including the comment // == SECTION Your Section Header Name in the included file, and you'll get multiple elements with headers automatically.
-
-

-
-

-
-A pass/fail summary is automatically added to the top of the page, though you can use <div id="doctest-output"></div> to position it someplace specific (as we did in this tutorial).

Subject: [PATCH 2/5] Remove jQuery and replace its Deferreds with native
 promises
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

jQuery was the client's last vendored dependency and its promise primitive.
Both are gone.

src/dom/dom.js is a ~700-line stand-in providing the subset of the jQuery API
the client actually called — nothing more. Rewriting ~500 call sites as
querySelectorAll + loops would have ballooned ui.js and forms.js and invited
transcription bugs, so the call sites are almost unchanged; only the import
moved. It is covered by 43 unit tests pinning the behaviours those call sites
depend on, including the surprising ones: attr() yielding undefined rather
than null for a missing attribute, `return false` in a handler meaning
preventDefault + stopPropagation, and .end() restoring the previous set.

Two jQuery behaviours needed explicit support rather than deletion:

- The non-standard pseudo-selectors. `:visible` is used by windowing.js and
  `:password` is the default value of the ignoreForms config, and neither is
  valid CSS, so they are translated before hitting querySelectorAll.
- Progress notifications on deferreds. who.js reports users as it discovers
  them and ui.js refreshes the invite list from each notification, so
  util.Deferred keeps notify()/progress() on top of a native promise. Unlike
  a jQuery Deferred it reports unhandled rejections instead of swallowing
  them — which is how the silent start-up failure in the previous commit
  managed to hide.

jqueryPlugins.js is replaced by src/dom/animate.js. Every animation there ran
through jQuery `step:` callbacks tweening a fake `borderSpacing` property and
writing four vendor-prefixed transforms per frame; they are Web Animations
and CSS transitions now, and the typing indicator is a CSS keyframe animation
that respects prefers-reduced-motion instead of a setInterval writing opacity.

Dead code removed, all of it dead because jQuery 1.9 removed the API it
depended on and jqueryPlugins.js only faked back $.browser.mobile:

- startup.js branched on $.browser.msie, undefined since 1.9.
- ui.js bound the dock anchor with .toggle(fn1, fn2), a signature removed in
  1.9, so collapsing the dock had silently done nothing for years. Restored
  as an explicit toggle.
- cursor.js's rotateCursorDown had no callers and its own comment said it no
  longer did anything.
- jqueryPlugins.js tested `matchMedia("screen and (max-screen-width: 480px)")`
  — not a valid media feature, so it never matched. $.isMobile() uses
  `(pointer: coarse)`.

Also: $.ajax in playback.js and $.each in forms.js became fetch and a normal
loop; $(window).unload in recorder.js became pagehide.

e2e coverage grew to cover what this change touched most: cursor propagation
between peers, and opening the chat and share windows (which exercises the
replaced animation code). The fixture now presents as a returning user,
because the first-run walkthrough is a modal whose backdrop covers the dock.

Subject: [PATCH 3/5] Rebuild voice as an audio and video mesh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The old webrtc.js could not work with more than two people, and was fragile
with two. It kept a single module-level RTCPeerConnection for the entire room
and broadcast its offers to everyone, so a third participant made every client
fight over the same connection. ICE candidates went into a scalar that each
new candidate overwrote, and any arriving before setRemoteDescription were
dropped. abort() discarded the connection without close(). toggleMute() was an
empty stub, so the muted state was unreachable and there was no way to hang up.

src/rtc/ replaces it:

  media.js       microphone and camera, acquired independently
  connection.js  one peer connection, using perfect negotiation
  mesh.js        the set of connections, and the signaling
  ui.js          dock buttons and video tiles

Signaling is addressed. rtc-description and rtc-ice carry a `to`, which
session.js filters on; rtc-offer/rtc-answer/rtc-abort are gone, since perfect
negotiation needs one description message and no abort channel. The filtering
is client-side: hub-worker's room.ts is deliberately a blind relay that
inspects nothing, and teaching it message types would couple client and server
versions to save bandwidth on a mesh that is capped at six peers anyway. This
is addressing, not privacy — every client still receives every frame, exactly
as before.

Getting three peers to connect reliably took four fixes, each a real defect:

- Both sides opened a connection to each other, so the two objects could end
  up negotiating against each other's discarded counterpart. Perfect
  negotiation resolves colliding offers on one connection; it cannot merge
  two. The peer with the lower clientId now opens, and the other creates its
  connection when the offer arrives.
- The answering side also added transceivers, which fires negotiationneeded,
  so it offered back at the moment it was about to answer — turning every
  single connection setup into a collision. It now stays quiet until it has
  applied the first remote description.
- connectTo() awaits the ICE configuration, so two callers racing for the
  same peer built two connections and one was orphaned in the map, never
  negotiating. Attempts are now shared and carry an epoch, so a creation that
  was in flight when the peer was reset discards itself.
- Candidates arriving while a connection was still being created were
  dropped. They are buffered per peer.

A peer that offers before the other side has joined the call gets no answer,
because a client that has not joined cannot respond. mesh.start() therefore
announces with rtc-join, and a peer parked in have-local-offer with no remote
description rebuilds that connection. Only that case: resetting anything not
yet "connected" also kills connections that are merely still gathering, and
with three peers announcing joins nothing ever settles.

Behaviour that did not exist before: mute (track.enabled, no renegotiation,
broadcast as rtc-state so peers can show a badge — a disabled audio track
still sends silence, so there is no other way to tell), camera on/off mid-call
via replaceTrack, hang-up, ICE restart on failure, device pickers, and video
tiles. Turning the camera off stops the track rather than disabling it, so the
hardware capture light goes out.

Configuration gains enableVideo (off by default), iceServers, getIceServers
for short-lived TURN credentials, and maxRtcPeers. Without TURN, symmetric-NAT
peers still fail — but visibly, and the docs will say so rather than repeating
the 2013 apology.

session.RTCSupported now also requires a secure context: navigator.mediaDevices
is undefined on http:// pages, where the old check passed and then threw inside
getUserMedia. That case gets its own dialog, since no permission prompt fixes it.

Also removed: the dead camera-avatar block bound to nine DOM ids that do not
exist in interface.html, and the mobile-only handler in ui.js that bound a
second click listener always claiming RTC was unsupported.

Tested with seven end-to-end cases covering two- and three-peer calls,
simultaneous joins (the glare the old code could not survive), enabling video
mid-call without dropping audio, mute propagation, a peer leaving, and hang-up.
They assert on getStats() packet counts, not just connectionState: ICE
completing does not prove media is flowing. Chromium's fake media devices
produce nothing in this container, so getUserMedia is backed by canvas and
WebAudio tracks — real MediaStreamTracks that negotiate and flow normally.

Subject: [PATCH 4/5] Update the docs for the rewritten client
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The WebRTC documentation was thirteen years out of date: it told readers they
needed Firefox Nightly, that support was coming "sometime in 2013", and
apologised for a missing TURN server by linking a 2013 issue. It now describes
what the client actually does — joining and muting, the camera button, why the
page has to be served over https, how to supply your own TURN servers (both
static and minted-per-session), and why calls are capped at six people.

The new configuration keys are documented: enableVideo, iceServers,
getIceServers and maxRtcPeers.

README build instructions replace the Grunt ones, and src/README.md replaces
the old per-module list. It leads with the two conventions that are not
obvious from reading any single file: core/togetherjs.js is imported rather
than read off window, and configuration must be read lazily because the bundle
evaluates before the host page has configured anything.

Deleted module-descriptions.json, which nothing had read since the docco task
went away.

The Playwright config now finds a browser in both places: it uses the Chromium
this dev container pins when that path exists, and otherwise lets Playwright
resolve the one `playwright install` fetched — so the suite runs in CI without
further configuration.

Note: a GitHub Actions workflow to run lint/build/unit/e2e on Node 22 is *not*
included, because this app lacks permission to push .github/workflows/. Travis
is gone, so there is currently no CI; adding a workflow is a one-file follow-up.

@@ -32,76 +32,70 @@ Setting up a development environment
 
 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
+  ``
+* `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.

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.

-## 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
 =================
 
-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.
