14:40 < humph_> I had a question about the best way to write conformance tests for WebVTT, specifically how and where to capture metadata about the different good/bad .vtt files 14:40 < humph_> should we put them in the .vtt file's comment block, in a separate file per test, in a wiki, in one file keyed by test file, etc. 14:41 < humph_> what's the right approach? 14:41 < jgraham> zcorpan: ^ 14:42 < jgraham> If it were me and I was writing a parser, I might develop a simple text format to embed the VTT and a desciption in 14:42 < zcorpan> humph_: webvtt doesn't currently support comments, so your options are in the cue text or in a separate file 14:42 < jgraham> Like we did for the HTML parser tests 14:42 -!- sicking [~chatzilla@nat/mozilla/x-qyqlmnzhabeqzbgc] has quit [Ping timeout: 240 seconds] 14:42 < jgraham> Then have a script to spit out the actual browser-readable tests 14:42 < humph_> jgraham: so a file that you'd split the .vtt out of at test time? 14:42 < jgraham> Yeah 14:43 < zcorpan> humph_: for some of my parser tests i've put json in cue data with expected settings/timings; and a separate json file with expected number of cues or "error" 14:43 < humph_> I was afraid of putting it in the cue text and making the tests unnecessarily large 14:43 < zcorpan> for my other parser tests i used html5lib style like jgraham suggested 14:44 < zcorpan> (i.e. for testing cue text parsing) 14:44 < zcorpan> i haven't released these tests but i intend to 14:44 < humph_> cool. I'm implementing webvtt in firefox with my class this term, just wanted to figure out the best way to start 14:44 < humph_> they are beginning with these tests 14:45 < zcorpan> ok 14:45 < jgraham> Nice project :) 14:45 < jgraham> And testing++ 14:45 < humph_> http://vocamus.net/dave/?p=1525 14:45 < humph_> yeah, should be fun 14:45 < jgraham> I hope you will release the results to W3C for inclusion in the official testsuite 14:46 < humph_> yeah, sylvia suggested the same 14:46 < humph_> I think that's a good plan 14:46 < jgraham> sylvia++ 14:46 < humph_> indeed 14:46 < humph_> alright, thanks for the ideas 14:46 < jgraham> If you need any help with test harness wrangling or getting the tests submitted feel free to ask me 14:47 < humph_> k 14:47 < humph_> I started by doing a node module to wrap the js parser 14:47 < jgraham> Or there is #testing on the W3C server 14:47 < humph_> https://github.com/humphd/node-webvtt 14:47 < humph_> so they could at least validate in a test harness 14:47 < zcorpan> i used testharness.js for testing the parser and the dom api, and reftests for rendering
