The following layout test is failing on iOS Simulator Release WK2 fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta.html Probable cause: Test has been a flaky failure since the test was added in https://trac.webkit.org/changeset/238946/webkit . Failing around 4 times on average in 500 iterations from r238946 up until r240911 Changes made in https://trac.webkit.org/changeset/240912/webkit made test fail a lot more frequently. During testing found from 240912 up until current r243537 is failing approximately 10 times 60 attempts (setting testing to exit after 10 failures) Reproduced with : run-webkit-tests fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta.html --iterations 500 -f --ios-simulator --exit-after-n-failures=10 Flakiness Dashboard: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fviewport%2Fios%2Fuse-minimum-device-width-for-page-without-viewport-meta.html --- /Volumes/Data/slave/ios-simulator-12-release-tests-wk2/build/layout-test-results/fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta-expected.txt +++ /Volumes/Data/slave/ios-simulator-12-release-tests-wk2/build/layout-test-results/fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta-actual.txt @@ -1,7 +1,7 @@ setMinimumEffectiveWidth(640.00) -window size: [640, 1096] +window size: [320, 548] square size: [64, 110] -zoom scale: 0.50 +zoom scale: 1.00 setMinimumEffectiveWidth(768.00) window size: [768, 1315]
