Using Mix to Run Phoenix Tests
Whether you knew it or not, Phoenix has already been generating default tests for you, such as test/controllers/video_controller_test.exs. We can go ahead and remove that file since it’s built for generic REST actions, not the features we’ve specifically built into our controller. We’ve added user authentication, validations, and the like to our videos, so we’ll start fresh with our VideoController tests. Delete the test/controllers/video_controller_test.exs file now, and then let’s see where our test suite stands:
| | $ mix test |
| | ... |
| | 1) test GET / (Rumbl.PageControllerTest) |
| | test/controllers/page_controller_test.exs:4 |
| | Assertion with =~ failed |
| | code: html_response(conn, 200) =~ "Welcome to Phoenix!" ... |
