public @interface DataJpaTest
```
Annotation that can be used in combination with @RunWith(SpringRunner.class) for a typical JPA test. Can be used when a test focuses only on JPA components.
Using this annotation will disable full auto-configuration and instead apply only configuration relevant to JPA tests.
By default, tests annotated with @DataJpaTest will use an embedded in-memory database (replacing any explicit or usually auto-configured DataSource). The @AutoConfigureTestDatabase annotation can be used to override these settings.
If you are looking to load your full application configuration, but use an embedded database, you should consider @SpringBootTest combined with @AutoConfigureTestDatabase rather than this annotation.
