/**
 * Testing the Gravity Flow API Functions.

 * Note: all the database operations are wrapped in a transaction and rolled back at teh end of each test.
 * So when debugging it's best not to stop the execution completely - best to let the tests run till the end.
 * This also means that if you check the database directly in the middle of debugging a test you won't see any changes - it'll appear empty.
