915518 - Make CrashTestUtils available to mochi tests

Status: NEW

(Toolkit :: Crash Reporting, defect)

Description

[Mark Hammond [:markh] [:mhammond]]

Some mochitest-browser tests need to force a crash.  CrashTestUtils looks perfect for the job, it it seems to only be available for xpcshell tests.  It would be ideal if all flavors of mochi could use CrashTestUtils instead of rolling their own code to both crash and cleanup the minidumps.

Eg, we currently have:

http://mxr.mozilla.org/mozilla-central/source/dom/ipc/tests/process_error_contentscript.js
http://mxr.mozilla.org/mozilla-central/source/toolkit/components/thumbnails/test/thumbnails_crash_content_helper.js

and e10s testing could make good use of it.

We could move CrashTestUtils.jsm into TESTING_JS_MODULES nowadays. Those modules get exposed as resource://testing-common/ in most of our test harnesses (xpcshell and Mochitest definitely work, IIRC). The only tricky bit is that it wants to load its shared library via ctypes, so we need to get that copied to the right place and make sure the jsm can find it.
