+==== Auto-configured jOOQ tests
+`@JooqTest` is similar to `@JdbcTest` but for jOOQ related tests. By default it
+will configure an in-memory embedded database and a `DSLContext`. Regular
+`@Component` beans will not be loaded into the `ApplicationContext`:

+	import org.junit.Test;

+	import org.springframework.boot.test.autoconfigure.jooq.JooqTest;
+	import org.springframework.test.context.junit4.SpringRunner;
+	
+	@RunWith(SpringRunner.class)
+	@JooqTest
+	public class ExampleNonTransactionalTests {
+		@Autowired
+		DSLContext create;
+	}
+----
+
+JOOQ tests are also transactional and rollback at the end of each test by default. 
+If that's not what you want, you can disable transaction management for a test or for 
+the whole as shown with 
+<<boot-features-testing-spring-boot-applications-testing-autoconfigured-jdbc-test,`@JdbcTest`>>
+
+If you prefer your test to run against a real database, you can use the
+`@AutoConfigureTestDatabase` annotation the same way as for `JdbcTest` or `DataJpaTest`.

+A list of the auto-configuration that is enabled by `@JooqTest` can be
