1050530 - using "mach mochitest-plain" to run a single test fails most of the time

Status: NEW

(Testing :: Mochitest, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

In a freshly-built tree (amd64 Linux debug+opt), if I do:

  ./mach mochitest-plain layout/style/test/test_transitions.html

I get the error:

No tests could be found in the path specified.  Please specify a path that is a test file or is a directory containing tests.


If I then do:
  ./mach mochitest-plain layout/style/test/
that works, and after doing that, if I then do:
  ./mach mochitest-plain layout/style/test/test_transitions.html
it now works, even though it didn't before.

I think this is a recent regression, although I'm not completely sure given the weird ordering dependency.

Er, actually, now it doesn't work again.

My scrollback shows it clearly worked once, but not again.

FWIW, I'm on https://hg.mozilla.org/mozilla-central/rev/2f198e81ed98 plus local patches.

Could be a regression from bug 1014062.

dbaron said over IRC that his working copy didn't include it (see also comment #2, which is indeed before it merged, AIUI).
