Update Test Expectations
Comment on attachment 389806 [details] Update Test Expectations Clearing flags on attachment: 389806 Committed r255811: <https://trac.webkit.org/changeset/255811> I am able to reproduce this issue with the following command: run-webkit-tests xxx webgpu/whlsl/ensure-proper-variable-lifetime.html --iterations 5000 -f --exit-after-n-failures 5 -g --force [106/5000] webgpu/whlsl/ensure-proper-variable-lifetime.html failed unexpectedly (reference mismatch) [212/5000] webgpu/whlsl/ensure-proper-variable-lifetime.html failed unexpectedly (reference mismatch) [259/5000] webgpu/whlsl/ensure-proper-variable-lifetime.html failed unexpectedly (reference mismatch) [290/5000] webgpu/whlsl/ensure-proper-variable-lifetime.html failed unexpectedly (reference mismatch) [617/5000] webgpu/whlsl/ensure-proper-variable-lifetime.html failed unexpectedly (reference mismatch) Exiting early after 5 failures. 614 tests run. 609 tests ran as expected, 5 didn't (4386 didn't run): Regressions: Unexpected image-only failures (1) webgpu/whlsl/ensure-proper-variable-lifetime.html [ ImageOnlyFailure ] I was able to reproduce the issue on 255856. Description: webgpu/whlsl/ensure-proper-variable-lifetime.html This is a flaky imageonlyfailure. The first image failure that I see this on the dashboard was 10/152019 at r251120, but it was not a commit that seemed relevant that would have caused this. It appears the original test expectations were set to failure instead of imageonlyfailure. Modifying/correcting text expectation in https://trac.webkit.org/changeset/266564/webkit I attempted to reproduce the imageonlyfailure using the previously used reproduction steps, but was unable to reproduce using those or other combinations I tried at this time. The test was expecting a blue square outline with white background and center, and received a white square outline with black background and center.
