An Open Invitation to Enable your Favourite tests on B2G
Throughout most of our B2G test automation deployment, we've been very conscious about not enabling too many tests simply because we didn't have enough capacity on our test slaves to run them all. Regardless it was still bad enough as it was (many of you probably experienced very long wait times for results). Thanks to releng (and especially Rail Aliiev) we are now running most of our B2G tests in Amazon AWS which means we can be much more flexible in accomodating load.
One thing this means is we don't need to be as cautious about enabling larger sets of tests for B2G. So if you have a mochitest, xpcshell test, marionette/webapi, reftest or crashtest that you would like to see running on B2G emulators, now is the time to make sure it's enabled!
Determining if the test is already being run
Unfortunately not all harnesses have the same manifest format, so here is a quick guide for finding them:
- Mochitest: look at testing/mochitest/b2g.json. Make sure the test is contained within a manifest specified by the 'runtests' attribute and that it isn't listed in the 'excludetests' attribute
- Xpcshell: look at testing/xpcshell/xpcshell_b2g.ini. Make sure your test's root manifest is listed there and that it isn't skipped further down in a child manifest
- Marionette/Webapi: look at testing/marionette/client/marionette/tests/unit-tests.ini. Once again make sure the test's root manifest is listed and the test isn't skipped in a child manifest
- Reftest: look at layout/reftests/reftest.list. Same as above.
- Crashtest: look at testing/crashtest/crashtests.list. Same as above.
Alternatively you can open a full log on tbpl of a test run for the branch/suite you are interested in and do a ctrl-f for your test. Just note that if there are multiple chunks you'll need to do this for each chunk before you can be certain.
Enabling the test
Please file a bug in the test harness component (e.g testing/mochitest, testing/reftest, etc) and cc me (:ahal). Then write a patch to enable the test (or suite of tests) and push it to try with the syntax "try: -b o -p ics_armv7a_gecko -u <suite name> -t none". If you are trying to enable the test on a branch without try (e.g b2g18) then I can help test it and get it landed there.
If the test was specifically disabled, there's a good chance that it had failures or was intermittent. In this case I can help get you set up to run it locally so you can investigate if you want.
