</span>I don't have a use case for comparing junit and json. If anyone tried<br>
to compare json to our junit, they would see lots of differences because<br>
json does not respect the "expected-failures" filter. That filter will<br>
also be unusable for json, because of the same test name character<br>
conversion.<br></blockquote><div><br></div><div>I think that we should make the filter work for both. I'm not sure yet what the right solution is for that, but I think it's worth making happen, I think there are a lot of reasons for it, but the main one I see is that it would eliminate distinctions between the backends.</div><div><br></div><div>I also have a series I'm working on that uses json for the intermediate atomic writes, and then having a function that just converts the TestrunResult object generated at the end of the run into the output we want (like json or junit, or nunit, or whatever else). This reduces code duplication a lot and reduces the number of code paths that aren't being tested by me a lot. This is advantageous in unify the expected failure/crash code to use the native piglit names rather than the junit names, since we could apply it before converting the tests and writing them out. That feels like the best solution to me, though it may mean some work converting our existing crash/fail lists.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</span>It seems to me that it will be simpler for everyone to disallow<br>
junit/json comparisons. I just need a way for users to visualize a<br>
dozen junit test files for disparate platforms and test suites.<br></blockquote><div><br></div><div>It might be, but I suspect that someone will try it at some point. I imagine a workflow like:</div><div>1) developer gets a report about breaking some system</div><div>2) developer makes changes, and runs subset of piglit on their system</div><div>3) developer wants to compare those changes to the original junit </div></div><br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Dylan</div></div>
