We can leverage the work done for mochitest selftests and do something similar for reftest. To start we should check that failures/crashes/assertions/leaks turn the job orange.

See bug 1048446 for how to approach this.

Bug 1392390 - Refactor common code out of mochitest selftests and into a new moztest.selftest module,

https://reviewboard.mozilla.org/r/178798/#review183966

a bit of rubber stamping here- looks like a good refactor.

Bug 1392390 - Create a reftest selftest harness,

https://reviewboard.mozilla.org/r/178800/#review183968

please file a followup for the additional tests, the other nits might be easy to explain.

::: layout/tools/reftest/selftest/files/reftest-pass.list:3

> +!= green.html red.html

it owuld be nice to test more features in the .list files, a few come to mind:
http
skip-if
fuzzy-if
random-if
# commented out tests
include submanifests

::: taskcluster/ci/source-test/python.yml:168

we don't have a need for specifying desktop1604-test, it is the default now.

::: taskcluster/ci/source-test/python.yml:176
(Diff revision 1)

why do we need to start_xvfb, isn't that done in the desktop image?

Bug 1392390 - Create a reftest selftest harness,

Follow-up already filed in bug 1399155

This is all tested already by the reftest-sanity suite, so I don't think there's much value in adding a second integration test that does the same thing.

However, I do think there's value if we can somehow figure out how to unittest just the reftest manifest parsing portion of the harness. I don't know how easy that would be right now, but it is definitely something that would be possible with bug 1353461. In fact, having a place to add a test for this was the main reason I wanted to work on this selftest harness in the first place :).

So if it's ok with you, I'd like to drop this issue for now. But I'll definitely be adding a unit test for all this stuff as part of bug 1353461.

Good to know!

Good question, I'm not sure. I copied this from the mochitest-harness task, I'll do a try run without it and see if things still pass or not.. though I suspect xvfb is needed for Firefox to run.

Oh, actually 'docker-image' is a required key for source-test tasks, so this needs to be here.

Yes, this fails without xvfb:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=caf01cb44bf1007ddab4b42b206e89788b568ca8

I think this happens because for desktop tests, xvfb is set up via a script that gets called as part of the test command. This is a "source-test" task and that script doesn't get invoked by default for these kinds of tasks.
I think this is good to land. I did a bunch of retriggers in this try push and no sign of intermittents:
