we are turning on:

Ideally we will be able to for each suite we turned on:
* inspect which tests are unique to non-e10s and follow up with owners to determine what is required to make the tests work in e10s
* assess coverage and determine if there is large areas of code that is non-e10s specific which is only covered by running in non-e10s mode (note: other tests might cover this, android might, or e10s tests might cover it as well)
* file bugs to fix things
* when all things are fixed, only run in e10s mode.

in addition we currently run some of our jsdebugger based code coverage on linux64 opt builds and we specifically only run the tests in non-e10s mode- this is for:

I know this isn't web-platform-tests, nor reftest; but our coverage is not as dire as it would seem.  Android does run reftest, so any web-platform-tests that are exercising code in non-e10s mode or non-windows have a chance of lacking coverage.
Priority: -- → P3
Geoff, has there been a change here? I recently found a devtools test skipped in e10s that was no longer passing, so I tried to understand why CI didn't catch this. It looks like almost no tests are running in non-e10s now? Looking at for instance.

Note that I'm not asking for non-e10s tests to be re-enabled, but I'd like to confirm that this is the expected state, so that we can prioritize enabling the ~60 devtools tests still skipped in e10s correctly.

I'm not aware of a change.

I expect to see most tests running in a non-e10s configuration on linux32/debug only (and Android) and I see that in recent mozilla-central pushes for plain mochitests, plain reftests, wpt, etc. -- but I do not see mochitest-devtools-chrome included there.

I looked back about 6 weeks and saw no relevant scheduling changes.

I am a little surprised we are not running linux32/debug mochitest-devtools-chrome (e10s or not) and I don't immediately see how that is configured. Having a look...
Recall the non-e10s testing issue initially came up in bug 1386689 and was discussed in!topic/ ... although lots has changed since then.

> I am a little surprised we are not running linux32/debug mochitest-devtools-chrome (e10s or not)

Of course it turns out I wrote the patch to do that! (bug 1328915).

So in that sense, this is the expected state: We intentionally do not run linux32/debug mochitest-devtools-chrome, and we intentionally run most non-e10s tests only on linux32/debug.

I haven't read through all the related history. I think it is possible that we did not explicitly decide to stop running non-e10s devtools -- but that's where we are.

As discussed on IRC, I think this is fine for DevTools, we are making progress on Bug 1387330
