901293 - Cannot run mochitest-browser tests because mach is searching for mozinfo.json in the wrong directory

Status: RESOLVED DUPLICATE of bug 901136

(Firefox Build System :: General, defect)

Description

[Ivan Alagenchev :ialagenchev]

mach appears to be searching for mozinfo.json in the wrong directory. This prevents me from running mochitests. Here is the output I get on a brand new checkout of the repository: 

ialagenchev@ialagenchev:~/mozilla-central-copy/browser/devtools/webconsole/test$ ls *hsts*

mach: error: Unable to file build information file (mozinfo.json) at this location: /Users/ialagenchev/mozilla-central-copy/obj-x86_64-apple-darwin12.3.0/dist/Nightly.app/Contents/MacOS/firefox/mozinfo.json

mozinfo.json is in the root of the obj dir: 
ialagenchev@ialagenchev:~/mozilla-central-copy$ find . -name mozinfo.json
./obj-x86_64-apple-darwin12.3.0/mozinfo.json

Is there a work-around that I can use so that I can continue my work, while this is getting resolved?

Are you running latest mozilla-central? There have been many bugs/fixes in the past week regarding this issue.

Yes, I just did a fresh checkout from git://github.com/mozilla/mozilla-central.git

FWIW - I'm getting this problem on Win 7 64-bit as well. And it's reproducing with mochitest-plain as well.

Usage: Usage instructions for runtests.py.
    All arguments are optional.
    If --chrome is specified, chrome tests will be run instead of web content tests.
    If --browser-chrome is specified, browser-chrome tests will be run instead of web content tests.

My command I ran after building a debug build was:

./mach mochitest-plain content/media/test_mediarecorder_creation.html

Also a regression - this was working a few days ago.

Looks like that error comes from:

Looks like someone already filed this bug and has a patch.
