Junit Test cases for Spring MVC 4 controller to check @PathVariable parameters in @RequestMapping
提问by Nishant Kumar
I have following controller code for which I have to write JUnit test case.
我有以下控制器代码，我必须为其编写 JUnit 测试用例。
public class EquipmentController {
private Map<String, Equipment> equiList = new HashMap <String,Equipment>();
@RequestMapping("/rest/equipment/{Number}")
public Equipment getEquipment(@PathVariable String Number){
if(!equiList.containsKey(Number)){
lNumber = DEFAULT;
}
return equiList.get(Number);
}
}
I'm writing the JUnit test case for the same as below:
我正在编写 JUnit 测试用例，如下所示：
import static org.springframework.test.web.ModelAndViewAssert.*;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({/* include live config here
e.g. "file:web/WEB-INF/application-context.xml",
"file:web/WEB-INF/dispatcher-servlet.xml" */})
public class EquipmentControllerTest {
@Inject
private ApplicationContext applicationContext;
private MockHttpServletRequest request;
private MockHttpServletResponse response;
private HandlerAdapter handlerAdapter;
private EquipmentController controller;
@Before
public void setUp() {
request = new MockHttpServletRequest();
response = new MockHttpServletResponse();
handlerAdapter = applicationContext.getBean(HandlerAdapter.class);
// Get the controller from the context here
controller = new EquipmentController();
}
@Test
public void testgetEquipment() throws Exception {
request.getUriString()("lNumber");
final Equipment equip = handlerAdapter.handle(request, response,
controller);
assertViewName(equip, "view");
}
}
But am not sure if this test classis correct or not as I am new to JUnit.
但是我不确定这个测试类是否正确，因为我是 JUnit 的新手。
Can anyone please suggest how to do this.
任何人都可以请建议如何做到这一点。

Create a mock of your controller and use MockMvcto test your methods:
创建您的控制器的模拟并用于MockMvc测试您的方法：
import static org.springframework.test.web.ModelAndViewAssert.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({/* include live config here
e.g. "file:web/WEB-INF/application-context.xml",
"file:web/WEB-INF/dispatcher-servlet.xml" */})
public class EquipmentControllerTest {
private MockMvc mockMvc;
private EquipmentController controller;
@Before
public void setUp() {
this.mockMvc = MockMvcBuilders.standaloneSetup(equipmentController).build()
}
@Test
public void testgetEquipment() throws Exception {
this.mockMvc.perform(get("/rest/equipment/{Number}", 3))
.andExpect(status().isOk())
}
}
where "3" represents value of your path variable.
其中“3”代表路径变量的值。
