Now that we have one test scenario entered, let's give it a whirl. In one window, start the Notes test infrastructure:

$ cd test-compose
$ docker-compose up --force-rebuild

Then in another window:

$ docker exec -it userauth bash
userauth# PORT=3333 node ./users-add.js
userauth# exit
$ cd test-compare/notesui
$ NOTES_HOME_URL=http://localhost:3000 mocha --no-timeouts uitest.js 

  Notes
    Login
      √ should click on login button
      √ should fill in login form (72ms)
      √ should return to home page (1493ms)

  3 passing (3s)

The NOTES_HOME_URL variable is what the script looks for to direct the Chromium browser to use the Notes application. To run the tests, we should use Docker Compose to launch the test infrastructure, and then ensure the test user is installed in the user database.
