  This module defines the setup for tests requiring

  You may define functions here to be used as helpers in
  your tests.
  Finally, if the test case interacts with the database,
  it cannot be async. For this reason, every test runs
  inside a transaction which is reset at the beginning
  of the test unless the test case is marked as async.
