Bug 64921 – Layout tests for validating the new WebVTT Parser

• Component: Media
• Status: RESOLVED FIXED

[Anna Cavender]

These tests will validate a new WebVTT parser.

Please note, the WebVTT parser is currently under review (https://bugs.webkit.org/show_bug.cgi?id=62882) and the <track> feature is not fully implemented (more patches coming soon): https://bugs.webkit.org/show_bug.cgi?id=43668

new layout tests for webvtt parser

This is not a complete list and a few more tests are coming soon: e.g. validating cue content text.  I am unsure of all of the test_expectations.txt files that need to have SKIPs, so please advise.  Thanks Silvia Pfeiffer for creating the test case .vtt files.

new layout tests for webvtt parser

These look great, thanks! I wonder if it might make sense to put all of these in a "tracks" directory inside of LayoutTests/media. Besides making it easier to find all track specific tests, it would allow you to skip all track tests with a single entry in the skipped list.

moving tests to media/track

Good idea, Eric.  Tests are moved.

Nit: I think the WebKit style is to have a space on both sides of the '+':  video.textTracks[" + i + "] (here and elsewhere).

Nit: I think it would be slightly clearer to increment the global in allTestsEnded (here and elsewhere).

updating to ToT

Let's get these in even though there might be more tests coming soon.  Also, looks like it may have to be committed manually: I think some funky characters in the test files are preventing the patch from applying.

None of these tests should be run on *any* platform at the moment.

Please add them to the skipped list then.
