1134791 - Testharness tests don't show their output in-browser even if you're only running one test

Status: RESOLVED FIXED

(Testing :: web-platform-tests, defect)

Description

[Boris Zbarsky [:bzbarsky]]

This is about mochitest th tests, but ms2ger told me to file here....

Running a single mochitest normally lets you see in the browser which assertions failed, without having to grovel the log.  But th tests don't show anything at all in browser, even if you're running only one test.

Isn't the test run in a suframe in mochitest even when running a single test?

Applied the patch, ran:

  mach mochitest-plain dom/bindings/test/test_bug773326.html

and the output is not there.  So this doesn't work, afaict...

Fwiw, I checked and parent is the test harness <http://mochi.test:8888/tests/?stuff> while this is the actual subframe the test is loaded in.
