This module defines the setup for tests requiring

access to the application's data layer.

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.
