 Now an **`SQLite`** database has been created. It has the name `foo.sqlite3`, or generically `<module>.sqlite3`. It's a database with a single table. There you can add the name of the method to test, and its input and expected output. Don't worry if you haven't already written it in `<module>.py`: you can set a `0` in the `perform_test` column, or even if it is set to 1 and the method doesn't exist, a `PyUnit` pragma is used specifiying the method is not implemented yet.
 
 So, now you can rename `test_foo.py` to your `test_<module>.py` and run it once to create the database. Then you can start adding tests into the database, and writing your methods. Run `test_<module>.py` whenever you want to pass the tests.
