Functional / regression test suite for amo-validator, the Add-on validator used at http://addons.mozilla.org/
You need Python 2.6 or higher. Then clone this repo:
git clone git://github.com/mozilla/test-amo-validator.git
Install the dependencies:
cd test-amo-validator pip install -r requirements.txt
You'll probably want to do all of this inside a virtualenv using virtualenvwrapper.
cd test-amo-validator nosetests
Then make a cup of tea while all of those tests run. It takes a while.
