Performed test isolation run with 100 iterations. Due to a bug in the test isolation the directory and test isolation runs failed with errors due to the incorrect test paths:

'MOZHARNESS_TEST_PATHS': '{"crashtest": ["file:///builds/worker/workspace/build/tests/reftest/tests/accessible/tests/crashtests"]}'
'MOZHARNESS_TEST_PATHS': '{"crashtest": ["file:///builds/worker/workspace/build/tests/reftest/tests/accessible/tests/crashtests/1402999.html"]}'

See bug 1557038 comment 17

During the full tests, reproduced failures 4 times. 3 times with the same assertion once with the same test. Once found a different assertion.

Comment 3

[Bob Clary [:bc] (inactive)]

After fixing the handling of failures in the test isolation I re-ran crashtests on try

Out of 100 runs of the original task, it reproduced this assertion once out of 111 attempts. Running test-isolation on the failure reproduced this assertion 3 times out of 100 with the full crashtest, 2 times out of 100 for the individual tests and none for the directory test.

This reproduces for me locally on linux64 almost immediately

./mach crashtest --repeat 100 --filter 515726-1.html ./js/xpconnect/crashtests/crashtests.list
