การทดสอบการผสานรวมด้วย @SpringBootTest

What is an Integration Test

@SpringBootTest

@SpringBootTest
class ApplicationIntegrationTest {
    @Autowired
    UserService userService;

    @Test
    void contextLoads() {
        assertThat(userService).isNotNull();
    }
}

WebEnvironment Modes

@SpringBootTest(
    webEnvironment = WebEnvironment.RANDOM_PORT)
class ApiTest { }

Testing with TestRestTemplate

@Autowired
TestRestTemplate restTemplate;

@Test
void getsUser() {
    ResponseEntity<User> response =
        restTemplate.getForEntity("/users/1", User.class);
    assertThat(response.getStatusCode())
        .isEqualTo(HttpStatus.OK);
}

WebTestClient

@Autowired
WebTestClient webTestClient;

@Test
void getsUser() {
    webTestClient.get().uri("/users/1")
        .exchange()
        .expectStatus().isOk()
        .expectBody()
        .jsonPath("$.name").isEqualTo("Alice");
}

Using a Test Database

@SpringBootTest
@AutoConfigureTestDatabase
class RepositoryIntegrationTest {
    @Autowired UserRepository repository;
}

Test Properties

@SpringBootTest
@TestPropertySource(properties = {
    "feature.enabled=false"
})
class FeatureTest { }

Activating Profiles

@SpringBootTest
@ActiveProfiles("test")
class ServiceTest { }

Transactional Rollback

@SpringBootTest
@Transactional
class UserPersistenceTest {
    @Test
    void savesAndRollsBack() {
        repository.save(new User("Alice"));
    }
}

Slicing for Speed

@DataJpaTest

@DataJpaTest
class UserRepositoryTest {
    @Autowired UserRepository repository;

    @Test
    void findsByName() {
        repository.save(new User("Alice"));
        assertThat(repository.findByName("Alice"))
            .hasSize(1);
    }
}
