The test imported/w3c/web-platform-tests/navigation-timing/test_performance_attributes.sub.html is flaky and sometimes it fails. When it fails it outputs this diff: --- /home/buildbot/worker/gtk-linux-64-release-tests/build/layout-test-results/imported/w3c/web-platform-tests/navigation-timing/test_performance_attributes.sub-expected.txt +++ /home/buildbot/worker/gtk-linux-64-release-tests/build/layout-test-results/imported/w3c/web-platform-tests/navigation-timing/test_performance_attributes.sub-actual.txt @@ -1,4 +1,4 @@ -PASS Check that performance.timing has reasonable values for secureConnectionStart and other attributes +FAIL Check that performance.timing has reasonable values for secureConnectionStart and other attributes assert_greater_than_equal: performance.timing.secureConnectionStart >= performance.timing.connectStart expected a number greater than or equal to 1617313048851 but got 0 Passing something like "--repeat-each=500" to run-webkit-tests may help to reproduce the issue
