[JSC] Run WPT Wasm tests in run-jsc-stress-tests' wasm.yaml
https://bugs.webkit.org/show_bug.cgi?id=319669
rdar://182513824
Reviewed by Yusuke Suzuki.
Run the imported Web Platform Tests WebAssembly suite
(LayoutTests/imported/w3c/web-platform-tests/wasm/{core/js,jsapi}) directly in
the jsc
command-line shell, diffing stdout against the committed -expected.txt
baselines. This
exercises the tests across the full wasm JIT-configuration matrix
(BBQ/OMG/no-CJIT/eager/
SIMD/...) that the browser layout-test run does not cover.
Three harness shims bracket each test to reproduce the browser testharness
reporting path
in a shell that has no DOM or event loop:
- wpt-harness-pre.js supplies self and a no-op console before testharness.js
loads.
- wpt-harness-mid.js drains microtasks (so the WAST harness's deferred import
registry
Proxy is installed before the test body reads it) and marks the run
explicit_done.
- wpt-harness-post.js registers a completion callback that prints the PASS/FAIL
text in
the committed baseline format, then calls done().
run-jsc-stress-tests gains recursive collection support (one yaml entry per
suite root
instead of per proposal directory) and a data-returning wasm JIT-config matrix
shared by
the new runners.
async_index.js reduces the assertion-location stack in each assert description
to
basenames so the text is identical whether the tests are served over HTTP by
the WPT
server or loaded from local files by a shell; the core baselines are
regenerated to match.
jsc gains --enable-all-experimental-features, generated from the JSC
web-preference
feature flags via FOR_EACH_JSC_EXPERIMENTAL_WEB_PREFERENCE_OPTION, mirroring
WebKitTestRunner's --enable-all-experimental-features. run-jsc-stress-tests
passes
it when running WPT tests. In a future change we can apply it to other test
drivers.
