Baz.TestSupport.DataCase (baz v0.0.6)

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 Baz.DataCase, async: true, although this option is not recommended for other databases.

assert "password is too short" in errors_on(changeset).password
