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,
|
||
|
|
we enable the SQL sandbox, so changes done to the database
|
||
|
|
are reverted at the end of every test. If you are using
|
||
|
|
PostgreSQL, you can even run database tests asynchronously
|
||
|
|
by setting `use PokemonCouture.DataCase, async: true`, although
|
||
|
|
this option is not recommended for other databases.
