/**
 * Annotation for a JPA test that focuses <strong>only</strong> on JPA components.
 * <p>
 * Using this annotation only enables auto-configuration that is relevant to Data JPA
 * tests. Similarly, component scanning is limited to JPA repositories and entities
 * ({@code @Entity}).
 * <p>
 * By default, tests annotated with {@code @DataJpaTest} are transactional and roll back
 * at the end of each test. They also use an embedded in-memory database (replacing any
 * explicit or usually auto-configured DataSource). The
 * {@link AutoConfigureTestDatabase @AutoConfigureTestDatabase} annotation can be used to
 * override these settings.
 * <p>
 * SQL queries are logged by default by setting the {@code spring.jpa.show-sql} property
 * to {@code true}. This can be disabled using the {@link DataJpaTest#showSql() showSql}
 * attribute.
 * <p>
 * If you are looking to load your full application configuration, but use an embedded
 * database, you should consider {@link SpringBootTest @SpringBootTest} combined with
 * {@link AutoConfigureTestDatabase @AutoConfigureTestDatabase} rather than this
 * annotation.
 * <p>
 * When using JUnit 4, this annotation should be used in combination with
 * {@code @RunWith(SpringRunner.class)}.
