/**
 * Utility module that creates a simple environment where a correctly configured database and session is set up.
 * This can be used in tests where it is important to access a REAL database (e.g. for testing indices/views).
 * If you only use some functions of the EntityMapper then you should rather use the {@link MockedTestingModule}.
 *
 * When using this module, make sure to destroy the Database in `afterEach` in order to have a fresh database in each test:
 * ```javascript
 *  afterEach(() => TestBed.inject(Database).destroy());
 * ```
