test: added new tests for several corner cases - #118
Conversation
Add OP#12 and OP#6 cases where the cross-dialect gts:// $ref lives on an ancestor and the descendant derives by chained-id re-declaration, so it references neither the ancestor nor the foreign-dialect target. An implementation that walks only the selected type's reference graph accepts this; validating the whole chain plus its reference closure must reject it (spec 11.0 and 12). Signed-off-by: Artifizer <artifizer@gmail.com>
These black-box tests pin down behaviour that was implementation-defined in practice and diverged across implementations: - OP#1: /validate-id must reject the gts:// URI form. Identifiers are validated in bare canonical form; the scheme exists only to embed an id in JSON Schema $id/$ref and is stripped by those callers. - OP#6: $ref sibling keywords must still constrain an instance under Draft 2019-09/2020-12 (the referenced schema is inlined and its siblings applied), so a sibling constraint is not silently dropped. - x-gts-ref: an exact (non-wildcard) reference must match on a segment boundary rather than by string prefix; and a oneOf whose branches share structural keywords and differ only by x-gts-ref must accept a valid target instead of rejecting every value. Signed-off-by: Artifizer <artifizer@gmail.com>
Add a conformance case pinning that a standalone, uniformly Draft-07 type may use tuple-form `items` (`"items": [<schema>, ...]`) inside its `x-gts-traits-schema`. Draft-07 spells tuple validation this way; 2020-12 renamed it to `prefixItems` and made `items` a single schema. Previously the only coverage for `gts.x.test13.tdialectinherit.ok.v1~` was the mixed-dialect reverse case, which asserts only that a 2020-12 child of this Draft-07 root is rejected. Nothing asserted the standalone Draft-07 parent itself is valid, so an implementation that compiles each trait-schema fragment against a hard-coded default dialect instead of the host document's dialect could reject legal Draft-07 tuple `items` while still passing the suite. The new case registers such a type and asserts /validate-type-schema returns ok=true. It passes on gts-go, gts-python, gts-ts and gts-dotnet and fails on gts-rust, which evaluates the fragment under the 2020-12 metaschema and reports the tuple array "is not of types boolean, object". A distinct type id keeps the case self-contained and independent of test ordering and in-memory registry state. Signed-off-by: Artifizer <artifizer@gmail.com>

Existing oneOf/anyOf x-gts-ref coverage only exercised combinators where
every branch declares an x-gts-ref. The common "nullable reference" shape
mixes an x-gts-ref branch with a neutral structural branch, e.g.
oneOf: [{"type":"string","x-gts-ref":"..."}, {"type":"null"}].
An implementation that runs its own x-gts-ref combinator pass must treat a
branch without an x-gts-ref as neutral rather than always-matching;
otherwise a valid string reference counts against every branch and a valid
value is rejected by the oneOf exactly-one rule. Add a conformance case
that registers such nullable oneOf/anyOf holders and asserts that both a
valid reference and null validate successfully.

Prior oneOf coverage used a concrete GTS pattern in every branch, so a
oneOf that mixes an x-gts-ref "/$id" self-reference branch with a concrete
sibling pattern was never exercised. oneOf requires exactly one matching
branch, so an implementation that treats "/$id" as always-matching (for
example a JSON Schema engine that evaluates x-gts-ref as a keyword but
short-circuits "/$id" to valid because it lacks the selected type) makes a
value matching only the sibling satisfy both branches and wrongly rejects a
valid value.
Add a conformance case with ref: oneOf[{"/$id"}, {concrete sibling}] and
assert that both a value matching only the sibling and a value matching only
"/$id" validate successfully.

Batch type-schema registration must honor ?validate and ?gts-ref-validation per entry exactly as POST /entities does. Add conformance cases that pin this: with validate=true an entry with an unresolved $ref is rejected while the same forward reference is accepted without validate, a valid self-contained schema still registers under validate=true (guarding against over-rejection), and a malformed gts-ref-validation mode refuses the whole batch with 422 before any entry is registered. Signed-off-by: Artifizer <artifizer@gmail.com>
Extend the POST /type-schemas?validate=true coverage for the staging model where entries are validated before being published: - order-independence: a batch entry may $ref or inherit from another entry that appears later in the same batch and both still register - atomicity: in a mixed batch only the entries that pass validation are committed; an invalid entry is never registered and is absent afterwards - a concurrency probe that keeps several wildcard-list workers running across 100 back-to-back registrations and asserts an uncommitted/invalid entity is never observable, regardless of its GTS id Signed-off-by: Artifizer <artifizer@gmail.com>
The existing "never expose an uncommitted entity" probe only uses valid entries that are independent of the failing one, so two batch guarantees went untested. Add two conformance cases for POST /type-schemas?validate=true: - A survivor that depends on a discarded sibling must not be committed: under any-present ref validation, B x-gts-refs A while A x-gts-refs a missing type; B passes against the fully staged set but A fails, and a single-pass implementation would commit B with a dangling reference. Both must be rejected and neither retrievable. - A batch that carries the same id twice with different content must not commit both entries; the aggregate ok must be false.

The child drops the ancestor’s ext constraint, so OP#12 can reject it even if the cross-dialect $ref is ignored ({"ext": 42} passes the child but fails the base). Please redeclare ext compatibly without $ref to isolate the dialect check; the OP#6 instance test has the same issue.
Upd: This illustrates why #102 should define stable error codes, so negative tests can assert the intended failure reason.

Good catch, fixed in commit b5f1136. Both the OP#12 and the OP#6 ancestor cross-dialect tests now redeclare ext compatibly in the descendant (a plain object without $ref), and the OP#6 instance supplies a valid ext object. The descendant is therefore derivation-compatible with its base, so the only remaining reason to reject it is the ancestor's cross-dialect $ref — which isolates exactly what these tests intend to cover. Agreed that stable error codes (#102) would let negative tests assert the intended failure reason directly; that's out of scope for this PR.

This test captures the intended behavior. The startsWith wording in §9.6 is incorrect for concrete instance IDs: ...thing.v1 must not match ...thing.v12. Only type IDs ending in ~ match themselves and descendants; the spec should say this explicitly. Please remove the startsWith rule from the spec.

Agreed, fixed in commit 85a79a4. Removed the startsWith rule from README §9.6. Concrete reference matching is now boundary-aware: a Type Identifier (ending in ~) matches itself and any derived/instantiated identifier under it, while a concrete Instance Identifier (not ending in ~) requires an exact match and MUST NOT match textual prefix supersets across segment or version boundaries (e.g. ...thing.v1 no longer matches ...thing.v12). The implementation notes were updated to match.

The current OpenAPI contract for POST /type-schemas has no validate or gts-ref-validation parameter, so full per-entry validation is not yet a conformance requirement. Please define the batch validation behavior in the spec and OpenAPI before requiring it in these tests.

Addressed in commit b0acf7c. Added the validate (boolean, default false) and gts-ref-validation (none|any-present|any-valid, default any-valid) query parameters to POST /type-schemas in tests/openapi.json, and documented the batch validation behavior in README §9.3 (parameter semantics, order-independent intra-batch $ref/inheritance resolution under validate=true, 422 on a malformed mode, and the atomicity/isolation guarantee that only passing entries are committed). Full per-entry batch validation is now a defined conformance requirement in both the spec and the OpenAPI contract before the tests require it.
Batch Type Schema registration is exercised by the OP#6 conformance tests with ?validate and ?gts-ref-validation, but neither the OpenAPI contract nor the spec declared them, so full per-entry validation was not a documented conformance requirement. Add both query parameters to POST /type-schemas in tests/openapi.json (validate: boolean default false; gts-ref-validation: none|any-present| any-valid default any-valid) and document the batch registration behavior in README §9.3: parameter semantics, order-independent intra-batch reference and inheritance resolution under validate=true, rejection of a malformed mode with 422, and the atomicity/isolation guarantee that only entries passing validation are committed and invalid entries are never exposed to concurrent reads.

The prior §9.6 text described every concrete x-gts-ref operand as a startsWith prefix match. That is wrong for concrete instance identifiers: an operand such as ...thing.v1 would then leak across the version boundary and wrongly match an unrelated ...thing.v12 instance. Replace the startsWith rule with boundary-aware matching: a concrete Type Identifier (ending in ~) matches itself and any derived or instantiated identifier under it, while a concrete Instance Identifier (not ending in ~) requires an exact match and MUST NOT match textual prefix supersets across segment or version boundaries. Update the implementation notes to match. Signed-off-by: Artifizer <artifizer@gmail.com>
In the OP#6 and OP#12 ancestor cross-dialect tests the descendant dropped the
ancestor's ext constraint, so the descendant/instance could be rejected purely
on derivation incompatibility ({"ext": 42} passes the child but fails the base)
rather than on the ancestor's cross-dialect $ref.
Redeclare ext compatibly (a plain object without $ref) in the descendant type
and supply a valid ext object in the OP#6 instance, so the descendant is
derivation-compatible with its base and the only remaining reason to reject it
is the ancestor's cross-dialect reference, isolating exactly what the test
intends to cover.

…tion The registration paragraph stated that a combined registration-with-validation request is atomic — no new entity is committed if validation fails — while the adjacent Batch Type Schema Registration paragraph requires a mixed batch to commit passing entries while never committing failing ones. An implementer could not satisfy both rules for the same batch request. Scope the atomic no-commit rule explicitly to single-entity registration and cross-reference the batch section, which already documents per-entry partial success.
