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(/* Insert test application context here */)
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：
@Test
public 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));
}
@Test
public 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);
}
