Run tests

Testing requires SQLite and PostgreSQL for the coaster.sqlalchemy module. Create a test database in PostgreSQL::

$ createuser `whoami`
$ createdb -O `whoami` coaster_test

Testing also requires additional dependencies. Install them with::

$ pip install -r test_requirements.txt

To run tests::

$ pytest

Some tests are in the form of doctests within each function.
