1475192 - Make it possible to import modules from testing-common in reftests

Status: NEW

(Testing :: Reftest, enhancement)

Description

[Marco Castelluccio [:marco]]

It's currently not possible to import them, maybe testing-common is not registered as for xpcshell or mochitest (https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/testing/mochitest/runtests.py#1294).

I've tried to replicate what mochitest is doing, adding a tests.manifest file for registering testing-modules, but for some reason the substitution doesn't work well (the error moved from "component not found" to "file not found"). I've manually checked the manifest and the paths were correct, so I'm not entirely sure what's going on.

I think I might just cheat and do what we're already doing for StructuredLog.jsm: https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/layout/tools/reftest/jar.mn#7.
