Bug 176054

media/video-controls-in-media-document.html is a flaky failure according to the flakiness dashboard. This test was initially reported for failing with multiple other media tests however it has recently been consistently failing with media/video-controls-no-display-with-text-track.html only or on its own. The reverse is also true. There are still examples of these test failing in a much larger block as seen in the original bug: https://bugs.webkit.org/show_bug.cgi?id=173978 current build: https://build.webkit.org/results/Apple%20Sierra%20Release%20WK2%20(Tests)/r221294%20(3911)/results.html https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK2%20(Tests)/builds/3911 Diff for media/video-controls-in-media-document.html: --- /Volumes/Data/slave/sierra-release-tests-wk2/build/layout-test-results/media/video-controls-in-media-document-expected.txt +++ /Volumes/Data/slave/sierra-release-tests-wk2/build/layout-test-results/media/video-controls-in-media-document-actual.txt @@ -2,5 +2,5 @@ -EXPECTED (controls.offsetTop + controls.offsetHeight <= '240') OK +EXPECTED (controls.offsetTop + controls.offsetHeight <= '285'), OBSERVED 'NaN' FAIL Diff for media/video-controls-no-display-with-text-track.html: --- /Volumes/Data/slave/sierra-release-tests-wk2/build/layout-test-results/media/video-controls-no-display-with-text-track-expected.txt +++ /Volumes/Data/slave/sierra-release-tests-wk2/build/layout-test-results/media/video-controls-no-display-with-text-track-actual.txt @@ -7,6 +7,6 @@ EVENT(webkitfullscreenchange) ** Video controls should be shown on fullscreen ** -EXPECTED (panel.style['display'] != 'none') OK +TypeError: null is not an object (evaluating 'panel.style') END OF TEST
