First make sure you have pip installed.
It is recommended that virtualenv and virtualenvwrapper be used in conjunction with firefox-ui-tests. Start by installing these.
Then:
git clone https://github.com/mozilla/firefox-ui-tests.git
cd firefox-ui-tests
python setup.py develop
If you want to install everything including fixed versions of dependencies (e.g. for mozbase and marionette packages) as we do in our CI system run the following command:
pip install -r requirements.txt
There is also a requirements_optional.txt file, which will install some optional packages like pep8 and mozdownload.
To run all tests:
firefox-ui-tests --binary <path to firefox binary>
To run the update tests:
firefox-ui-update --binary <path to firefox binary>
To run a specific test or directory of tests:
firefox-ui-tests --binary <path to firefox binary> <path to test or directory>
For more options run:
firefox-ui-tests --help
Documentation for the puppeteer libraries are hosted on readthedocs.
