相当于 Spring Data 的 ReactiveCrudRepository 和 R2DBC 的 DataJpaTest

Question

For JpaRepository there is @DataJpaTest . @DataJpaTest allows for simple and isolated testing of JPA repositories in Spring.

We are using spring-data-r2dbc . Is there an equivalent of @DataJpaTest for ReactiveCrudRepository to test it in isolation?

Answer 1

Yes, as of Spring Boot 2.3 you can use @DataR2dbcTest to spin up a context for your R2DBC repositories (including the DatabaseClient ):

@DataR2dbcTest
class DataR2dbcTestIntegrationTests {

    @Autowired
    private DatabaseClient databaseClient;

    @Autowired
    private ConnectionFactory connectionFactory;

    @Autowired
    private MyRepository myRepository;

    @Test
    void testDatabaseClient() {
        this.databaseClient.execute("SELECT * FROM example").fetch().all()
             .as(StepVerifier::create).verifyComplete();
    }

    // …
}
