Mvc Test with mocks是集成测试还是单元测试

Question

如果我们在休息端点的 MvcMock 测试中有模拟，我们可以将其称为 integration test 吗？当然，我可以说 TestRestTemplate 测试是 integration test 因为当我测试端点时没有模拟。

MvcMock test

@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles("test")
internal class CreateProductRestControllerMvcTest {

    @Autowired
    private lateinit var mockMvc: MockMvc

    @Autowired
    private lateinit var objectMapper: ObjectMapper

    @MockkBean
    private lateinit var createProductService: CreateProductService

    @ParameterizedTest
    @ArgumentsSource(ValidCreateProductRequests::class)
    internal fun `POST a new Product, GIVEN without any exception, THEN return Product id and status 201`(request: CreateProductRequest) {
        // Given
        every { createProductService.invoke(request.toCommand()) } returns ProductId(1L)

        // When, Then
        this.mockMvc.post(REST_PRODUCTS) {
            contentType = APPLICATION_JSON
            content = objectMapper.writeValueAsString(request)
        }
            .andExpect {
                status { isCreated() }
                content { json((objectMapper.writeValueAsString(1L))) }
            }
    }
}

TestRestTemplate Test

@SpringBootTest(webEnvironment = RANDOM_PORT, classes = [Application::class])
@ActiveProfiles("test")
@Testcontainers
@FlywayTest
@ExtendWith(FlywayTestExtension::class)
class CreateProductRestControllerIntegrationTest {

    @Autowired
    private lateinit var restTemplate: TestRestTemplate

    private lateinit var headers: HttpHeaders

    @BeforeEach
    internal fun setUp() {
        headers = HttpHeaders()
        headers.contentType = MediaType.APPLICATION_JSON
    }


    @FlywayTest
    @ParameterizedTest
    @ArgumentsSource(ValidJsonRequestBodies::class)
    internal fun `POST new Product, GIVEN valid request, THEN returns 201`(json: String) {
        // Given
        val request: HttpEntity<String> = HttpEntity(json, headers)

        // When
        val result = restTemplate.postForEntity(REST_PRODUCTS, request, String::class.java);

        // Then
        assertNotNull(result.body)
        assertEquals(HttpStatus.CREATED, result.statusCode)
    }
}

在我看来，将其称为“集成测试”并不完全公平。通过模拟服务，您基本上是在测试您的控制器并测试序列化和反序列化的能力 JSON，这是一个完全有效的测试。

在 Spring 世界中，您可能会发现这些被称为“切片测试”，测试的重点是检查应用程序的给定层，而不是完全成熟的集成测试。有关它们的更多信息：
