Drupal 8 Forms and TDD, part 4: form submission

In part 1, I showed how you can start using TDD when writing Drupal code, and how to apply it to testing a custom file validation callback. In part 2, we tackled testing the form building, and in part 3, the form validation. In this final part, I'll show how you can test the form submission.
