Add your test as /tests/fooban.py and
  amend /tests/__init__.py

    ```python
    from tests.fooban import test as test_fooban
    __all__ = ['test_typeahead', ..., 'test_fooban']
    ```

  so you can access the test when importing the module

    ```python
    from tests import *
    [...]
    result = await test_fooban()
    ```
