This failure started from
https://ci.chromium.org/buildbot/chromium.chromiumos/linux-chromeos-rel/6813

and a CL which affects only on CrOS is
https://chromium.googlesource.com/chromium/src/+/35a5292481c4932de395906242f491f46baed743

Hanada-san, could you take a look if the revert trigger the failure?
IIUC, browser process fails to launch in the tests.

I don't think the revert CL is related to the failures. The CL touches the code running only when the virtual keyboard on Chrome OS is shown.

Could you tell me how to run the test on my local machine? I'd like to see reverting the revert fixes the test failure.

I made a revert (crrev.com/c/1009522) for the CL. We'll see whether it fixes the test failure or not.

The trybot used following command to run the test.

python ../../testing/scripts/run_telemetry_as_googletest.py ../../tools/perf/run_tests -v --browser=exact --browser-executable=./test_chrome --xvfb --skip=benchmarks.benchmark_smoke_unittest.BenchmarkSmokeTest.v8.runtime_stats.top_25 --skip=scripts_smoke_unittest.ScriptsSmokeTest.testRunTelemetryBenchmarkAsGoogletest


I have no strong evidence to point your revert commit triggered the failure.
I'd sheriff the failure.

Thank you for the information!

telemetry_perf_unittests passes in the last 5 consecutive runs. Maybe fixed by another CL?

Yes, maybe. All stacked tasks are gone.

What test is failing? Is it flaky?
