Writing Tests

Every feature you add must have tests. Use Django’s TestCase and its subclasses to write your tests. Your tests should reside in root tests directory, i.e., do not put your tests in apps or modules.

Here are few tips while writing tests:

• Run your tests multiple times to ensure they are not flaky.

• Run your tests in parallel and make sure nothing breaks.

• Make sure your tests are fast. Monitor your tests carefully and eliminate slow tests.

• Check coverage and make sure everything is covered. Keep in mind that having a high coverage does not necessarily mean everything is tested.

• If exposed as an API, your feature should have end-to-end tests as well as unit tests.
