We now have a tool in mozilla-central that has a much better UX for
running tests (mach). It's not perfect yet, but it's getting there
(please write patches!).
The build peers (or at least a few of us) really don't like the make
targets to run tests because they are awkward, both to maintain and for
people to use. mach and having Python drive everything offer compelling
advantages over simple make targets.
The make targets for running tests aren't used by buildbot (well, at
least a lot of them - there might be a straggler or two).
Putting this all together, the stage is set to remove the make targets
for running tests.
I'm writing this post to see what obstacles/resistance there are to
removing the make targets for running tests. Obviously a prerequisite is
having mach reach feature parity with the make targets. What other
concerns are there?
Before you deprecate the make targets, it would be nice if mach actually
works and there is documentation for it. I have so far not been able to
figure out how to run a test with mach. This is what I tried:
$ ./mach xpcshell-test
toolkit/mozapps/extensions/test/xpcshell/test_dictionary
.js
Traceback (most recent call last):
