SpringMVC controller测试较简单，从功能角度划分，可分为两种。一种是调用请求路径测试，另一种是直接调用Controller方法测试。
调用请求路径测试
通过请求路径调用，请求需要经过拦截器，再到对应的Controller方法处理
被测试代码示例
import com.agoura.agoura.entity.Members; import com.agoura.agoura.service.MembersService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.*; import javax.servlet.http.HttpServletRequest; @Controller @RequestMapping("/api") public class MembersController { @Autowired private MembersService membersService; @RequestMapping(value = "/user", method = RequestMethod.POST, produces = "application/json;charset=UTF-8") @ResponseBody public String getUser(HttpServletRequest request, @RequestBody String str, @RequestParam(value = "userId") String userId) { Members result = membersService.getMemberById(Integer.valueOf(userId)); return result.toString(); } } |
测试代码示例
import com.agoura.agoura.entity.Members; import com.agoura.agoura.service.MembersService; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.mockito.InjectMocks; import org.mockito.Mock; import org.mockito.Mockito; import org.mockito.MockitoAnnotations; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.MediaType; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.web.WebAppConfiguration; import org.springframework.test.web.servlet.MockMvc; import org.springframework.test.web.servlet.MvcResult; import org.springframework.test.web.servlet.request.MockMvcRequestBuilders; import org.springframework.test.web.servlet.setup.MockMvcBuilders; import org.springframework.web.context.WebApplicationContext; import static org.junit.Assert.assertEquals; import static org.mockito.Mockito.when; import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.model; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status; @RunWith(SpringJUnit4ClassRunner.class) //调用Spring单元测试类 @ContextConfiguration(locations = {"classpath*:spring-*.xml"}) //加载Spring配置文件 public class MembersControllerTest2 { @Autowired protected WebApplicationContext wac; @Mock private MembersService service; @InjectMocks private MembersController controller; //需要测试的Controller private MockMvc mockMvc; //SpringMVC提供的Controller测试类 private String url; @Before public void setUp() throws Exception { MockitoAnnotations.initMocks(this); mockMvc = MockMvcBuilders.standaloneSetup(wac).build(); } @Test public void testGetUser() throws Exception { url = "the URL to Controller"; Members m = new Members(3, "wangwu", 1, 5, "12131232342"); when(service.getMemberById(Mockito.anyInt())).thenReturn(m); MvcResult result = mockMvc .perform(MockMvcRequestBuilders.post(url) .accept(MediaType.APPLICATION_JSON) .param("userId", "3")) .andDo(print()) .andExpect(status().isOk()) .andExpect(model().attributeExists("name")) .andReturn(); assertEquals(m.toString(), result.getModelAndView().getModel().get("user").toString()); } } |
调用Controller方法测试
无法对拦截器和URL路径配置进行测试。测试方法类似于service层单元测试，可以对依赖的service层进行mock。
被测试代码示例
测试代码同调用请求路径测试方式部分一样
测试代码示例
import com.agoura.agoura.entity.Members; import com.agoura.agoura.service.MembersService; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.mockito.InjectMocks; import org.mockito.Mock; import org.mockito.Mockito; import org.mockito.MockitoAnnotations; import org.springframework.mock.web.MockHttpServletRequest; import org.springframework.mock.web.MockHttpSession; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.web.WebAppConfiguration; import org.springframework.test.web.servlet.setup.MockMvcBuilders; import static org.junit.Assert.assertEquals; import static org.mockito.Mockito.when; @RunWith(SpringJUnit4ClassRunner.class) //调用Spring单元测试类 @WebAppConfiguration //调用Java Web组件，如自动注入ServletContext Bean等 @ContextConfiguration(locations = {"classpath*:spring-*.xml"}) //加载Spring配置文件 public class MembersControllerTest { @Mock private MembersService service; @InjectMocks private MembersController controller; //需要测试的Controller private MockHttpServletRequest request; private MockMvc mockMvc; //SpringMVC提供的Controller测试类 @Before public void setUp() throws Exception { MockitoAnnotations.initMocks(this); request = new MockHttpServletRequest(); } @Test public void testGetUser() throws Exception { request.addParameter("userId", "100100"); // request.addParameter("id", "101010"); //如果需要从request取数据，可以在request中添加parameter Members m = new Members(3, "wangwu", 1, 5, "12131232342"); when(service.getMemberById(Mockito.anyInt())).thenReturn(m); String response = new String(); String result = controller.getUser(request, response, "3"); assertEquals(m.toString(), result); } } |
