Enabling tests on a production gitlab install

First, edit config/database.yml to have valid credentials for gitlabhq_development and gitlabhq_test database configs. Then:

cd /home/git/gitlab
sudo -u git -H bash
bundle install --deployment --without `mysql_or_postgres` aws
bundle exec rake setup
bundle exec rake test

To run a specific test:

bundle exec rspec spec/foo/bar_spec.rb
