Automatic update from web-platform-tests feat(runner): Integrate Test262 execution with wptrunner and add smoke tests [pt 3/5] (#56842) * feat(runner): Integrate Test262 execution with wptrunner and add smoke tests This commit completes the core integration of Test262 into the WPT runner (`wptrunner`), enabling the execution of Test262 JavaScript conformance tests within the browser environment. This work builds upon the manifest tooling (PR 1 #56840) and server-side handling (PR 2 #56841) to provide a full end-to-end testing solution for Test262. Key components introduced and integrated: - **Client-Side Harness:** New JavaScript files (`harness-adapter.js`, `testharness-client.js`, `testharness.js`) under `resources/test262/` provide the necessary environment for Test262 tests to execute in an `iframe` and report results back to the main WPT testharness. - **Test262 Assertion Libraries (Vendored):** For the purpose of enabling these initial smoke tests, the standard Test262 assertion libraries (`assert.js` and `sta.js`) are directly placed into `third_party/test262/harness/`. This provides the immediate dependencies required by the smoke tests. An autoamted vendoring solution, including version tracking via `vendored.toml`, will be implemented in a subsequent PR focused on automated updates, as described in the RFC. - **Wptrunner Integration:** Modifications to `tools/wptrunner/wpttest.py` and `tools/wptrunner/browsers/*.py` enable `wptrunner` to recognize the `test262` test type and execute it using existing testharness executors. - **Smoke Tests and Metadata:** A suite of basic Test262 smoke tests (`infrastructure/test262/`) and their corresponding expected results (`infrastructure/metadata/infrastructure/test262/`) are added to verify the correct functioning of the entire integration. - **Linting Exemption:** `lint.ignore` is updated to exclude the vendored Test262 harness files from linting, respecting their upstream style. This integration allows browser vendors to run Test262 directly with `wptrunner`, streamlining conformance testing efforts as specified in the RFC: https://github.com/web-platform-tests/rfcs/pull/229 This commit is the third in a series of smaller PRs split from the larger, original implementation in https://github.com/web-platform-tests/wpt/pull/55997. * address feedback * address more feedback * address feedback * address feedback * Apply suggestion from @jcscottiii * fix lint * move need third_party lint because other doesn't work * fix lint * Refactor Test262 integration to remove custom custom harness bridge This commit addresses reviewer feedback (jgraham) regarding the Test262 integration "reimplementing a subset of testharness.js". The architecture has been drastically simplified by eliminating the custom `postMessage` protocol between the Test262 iframe and the parent WPT test wrapper. Changes include: - Deleted `test262-harness-bridge.js` completely. - Updated the wrapper `<script>` generated by `tools/serve/serve.py` to expose a native `window.test262HarnessDone(status, error)` hook directly in the parent's `testharness.js` execution environment. - Refactored `test262-reporter.js` to natively dispatch test completions and harness errors to this synchronous hook instead of manually wrapping results in `{type: "complete"}` message payloads. - Ensured strict "Realm Isolation" is maintained for the `test262` tests, as required by `INTERPRETING.md`, by keeping all WPT globals cleanly isolated in the parent window. - Updated `tools/serve/test_serve.py` assertions to reflect the removed bridge dependency. - Leveraged `setTimeout` to safely elevate test harness crashes into the parent's macro-task queue, ensuring infrastructure `.ini` expectations (like timeouts and parsing ERRORs) correctly fail the WPT harness. * Update tools/serve/serve.py * update to docs from last commits * touch ups * nit * start to address feedback * finish feedback * tidy up * doc touchups * add missing support for phases * final touchups -- wpt-commits: 0a0fd8c16c2a51e2c9b915780962500cd641eda7 wpt-pr: 56842
