Whoa. Don't refer to `__init__` like this. What I mean by explicitly is actually list out the classes you're importing, instead of doing `import *`, because that can have undesirable consequences. See the other test files for examples.

```python
from huxley.api.tests import (CreateAPITestCase, DestroyAPITestCase,
                              ListAPITestCase, PartialUpdateAPITestCase,
                              RetrieveAPITestCase)
```
