In the gdk directory run `gdk restart` 1. Tail the logs in the `gitlab` directory with `tail -f log/development.log` 1. Then in the `gitlab/qa` directory run (update address if necessary) ``` bundle exec bin/qa Test::Instance::All http://192.168.254.28:3000/ -- qa/specs/features/ee/api/2_plan/epics_milestone_dates_spec.rb ``` If the test is run again, it passes until `gdk restart` is run again.
