Spring框架测试RESTful Web服务（控制器）离线，即没有服务器，没有数据库

Spring框架测试RESTful Web服务（控制器）离线，即没有服务器，没有数据库

这是一个建议，应该给你一些想法。我假设你熟悉

SpringJUnit4ClassRunner

和

@ContextConfiguration

。首先创建一个包含

PcUserController

和的测试应用程序上下文

PcUserService

。在

PcUserControllerTest

下面的示例类中，Jackson用于转换JSON消息，Mockito用于模拟。

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration()public class PcUserControllerTest {    MockHttpServletRequest requestMock;    MockHttpServletResponse responseMock;    AnnotationMethodHandlerAdapter handlerAdapter;    ObjectMapper mapper;    PcUser pcUser;    @Autowired    PcUserController pcUserController;    @Autowired    PcUserService pcUserServiceMock;    @Before    public void setUp() {        requestMock = new MockHttpServletRequest();        requestMock.setContentType(MediaType.APPLICATION_JSON_VALUE);        requestMock.addHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE);        responseMock = new MockHttpServletResponse();        handlerAdapter = new AnnotationMethodHandlerAdapter();        HttpMessageConverter[] messageConverters = {new MappingJacksonHttpMessageConverter()};        handlerAdapter.setMessageConverters(messageConverters);        mapper = new ObjectMapper();        pcUser = new PcUser(...);        reset(pcUserServiceMock);    }}

现在，我们拥有创建测试所需的所有代码：

@Testpublic void shouldGetUser() throws Exception {    requestMock.setMethod("GET");    requestMock.setRequestURI("/pcusers/1");    when(pcUserServiceMock.read(1)).thenReturn(pcUser);    handlerAdapter.handle(requestMock, responseMock, pcUserController);    assertThat(responseMock.getStatus(), is(HttpStatus.SC_OK));    PcUser actualPcUser = mapper.readValue(responseMock.getContentAsString(), PcUser.class);    assertThat(actualPcUser, is(pcUser));}@Testpublic void shouldCreateUser() throws Exception {    requestMock.setMethod("POST");    requestMock.setRequestURI("/pcusers/create/1");    String jsonPcUser = mapper.writevalueAsString(pcUser);    requestMock.setContent(jsonPcUser.getBytes());    handlerAdapter.handle(requestMock, responseMock, pcUserController);    verify(pcUserServiceMock).create(pcUser);}
