1288191 - Test dependencies not installed when running |mach test /path/to/single/test.js|

Status: RESOLVED DUPLICATE of bug 1286016

Description

[Eric Rahm [:erahm] (ni? for review in phab)]

I'm trying to run a single test after performing a |mach build|, but the test is failing because it's missing definitions from it's head.js file.

STR:
1) |mach clobber|
2) |mach build|
3) |mach test toolkit/mozapps/extensions/test/browser/browser_cancelCompatCheck.js|

This produces various failures such as:

> Uncaught exception - at chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_cancelCompatCheck.js:238 - ReferenceError: PREF_STRICT_COMPAT is not defined

PREF_STRICT_COMPAT is defined in a head.js file [1] and is not installed under the testing directory:

> [erahm@mozilla21268 mozilla-central]$ ll obj-x86_64-pc-linux-gnu-clang-release/_tests/testing/mochitest/browser/toolkit/mozapps/extensions/test/browser/
> total 12
> drwxrwxr-x 2 erahm erahm 4096 Jul 20 10:59 ./
> drwxrwxr-x 3 erahm erahm 4096 Jul 20 10:59 ../
> lrwxrwxrwx 1 erahm erahm  100 Jul 20 10:59 browser_cancelCompatCheck.js -> /home/erahm/dev/mozilla-central/toolkit/mozapps/extensions/test/browser/browser_cancelCompatCheck.js

If I run |mach test toolkit/mozapps/extensions/test/browser/| instead things work (but it runs a ton of tests I don't care about).

I'm fairly sure this is a dupe of bug 1286016, I'll post a patch there.
