Comment 1

[Gregory Szorc [:gps]]

The first part of your bug report is WONTFIX because we removed the mochitest make targets in bug 1248658.

The 2nd part with mach failing looks like comm-central foo :/

Comment 2

[Philip Chee]

So what's the mach equivalent for:
> TEST_PATH=suite/browser/test/browser/browser_bug561636.js mozmake -C ../objdir-sm/ mochitest-browser-chrome

Comment 3

[Gregory Szorc [:gps]]

`mach mochitest path/to/test`

Comment 5

Getting closer. Mach couldn't find my mozconfig. Set the env to: MOZCONFIG=/c/t1/hg/comm-central/mozconfig

I tried replacing all instances of 'firefox' with 'seamonkey' in mach_commands.py that didn't work either.

I tried renaming seamonkey.exe to firefox.exe but that didn't work either.

Anything else I can try?

Philip@lenovo-PC /c/t1/hg/comm-central
$ MOZCONFIG=/c/t1/hg/comm-central/mozconfig mozilla/mach  mochitest  suite/browser/test/browser/browser_urlbarCopying.js
It looks like you tried to run a mach command from an invalid context. The mochitest
command failed to meet the following conditions:

  is_buildapp_supported - Must have a firefox or b2g or android or mulet build.

Run |mach help| to show a list of all commands available to the current context.

testing/mochitest/mach_commands.py has a SUPPORTED_APPS variable that isn't recognizing comm-central and is refusing to run mochitests. This is a problem for projects not in tree :/

I recommend adding an environment variable or mach settings option to supplement this list or disable the check and allow out-of-tree applications to be detected.

I know nothing about Python except that it's a really terrible language. After a bit or random trial and error I managed to get mochitests to run with the attached patch.

I also had to fix several JavaScript errors:

JavascriptException: JavascriptException: ReferenceError: Cc is not defined
stacktrace:
        execute_script @runtests.py, line 1292
        inline javascript, line 7
        src: "let wm = Cc["@mozilla.org/appshell/window-mediator;1"]"
        Stack:

JavaScript error: chrome://mochikit/content/browser-test.js, line 6: ReferenceError: Cu is not defined

>>> I know nothing about Python except that it's a really terrible language.

Please don't jump to conclusions because of a lack of understanding. People obviously enjoy Python or it wouldn't be so popular. Of course, that doesn't mean it isn't a terrible language (JavaScript is a terrible language and it is popular) :)

See my earlier comment about doing this through environment variables. We don't want to have to create one-off references to every app that wishes to use the mochitest harness inside mozilla-central.
