To run the Selenium tests you will have to install Ruby (look at .rvmrc file for the exact version), the latest versions of RubyGems and Firefox (the default browser in which the tests run). The easiest way to install Ruby on Linux/Unix is RVM and on Windows RubyInstaller.
Update RubyGems and install the required RubyGems:
cd browsertests
gem update --system
gem install bundler
bundle install
You will need a file with credentials located at /private/wmf/secret.yml. For local testing, create a user named Selenium_user on your local wiki and record the password in this file as
mediawiki_password: password here
Run the tests with bundle exec rake, this should start Firefox.
The test run creates an HTML report in reports/ and an XML report (for Jenkins) in reports/junit.
To run a single test enter bundle exec cucumber features/FEATURE_NAME.feature.
The code repository is https://gerrit.wikimedia.org/r/#/admin/projects/qa/browsertests, the GitHub mirror is at https://github.com/wikimedia/qa-browsertests
The Jenkins instance that orchestrates the tests is hosted at https://wmf.ci.cloudbees.com/
The tests are run in multiple browsers at http://saucelabs.com/
