-    applied. This makes sure that we are testing "as if" we were actually applying this migration
-    to a database in the state it was in before introducing the new migration.
-
-    To set up a MigrationsTestCase, create a subclass of this class and set the following
-    class-level attributes:
-
-    - app: The name of the app that contains the migrations (e.g., `'api'`)
-    - migration_prior: The name* of the last migration file before the migrations you want to test
-    - migration_target: The name* of the last migration file we want to test
-
-    *) Specify the file names without a path or the `.py` file extension.
-
-    Additionally, overwrite the `setUpMigrationData` in the subclass to inject data into the
-    database before the migrations we want to test are applied. Please read the docstring of the
-    method for more information. An optional hook, `setUpPostMigrationData` is also provided.
