JUnit测试案例给错误

Question

我是新来编写测试用例：

我控制器低于：

@RequestMapping(value={"/addschool" }, method = RequestMethod.GET) 
     public final ModelAndView addschool(@ModelAttribute("addschool") Pricing pricing, Map<String, Object> map, 
       Model model, HttpServletRequest request) { 

       System.out.println("Name=" + pricing.getName() + " age=" + request.getParameter("age")); 

       ModelAndView mv = new ModelAndView(ADDSCHOOL); 
       return mv; 
      } 

和我的JUnit测试的情况是这样的：

public class AddSchoolTest { 

    @Autowired 
    private UserManagementController controller; 

    @Test 
    public void testAddSchool() { 

     ModelMap model = new ModelMap(); 
     HttpServletRequest request = new MockHttpServletRequest(); 
     Pricing pricing = new Pricing(); 
     String userName = "Laily"; 
     pricing.setName(userName); 
     //ModelAndView mav= controller.handleRequest(); 
     try{ 
     ModelAndView mav= controller.addschool(pricing, model,null, request); 
     //fail("Not yet implemented"); 
     assertNull(pricing); 
     assertFalse(model.isEmpty()); 
     Assert.assertEquals("addschool", mav.getViewName()); 
     }catch(Exception e){ 

     } 
    } 

} 

但我的问题即使我将删除“添加学校”，并把其他东西它将显示绿色，但如果我删除尝试和捕捉比在每种情况下它会给红。问题是什么。

完整的堆栈跟踪是这样的

正如pappu_kity所说，删除空的catch块会暴露事实，即您的controller字段为空 - 因此可能未被自动装配。

为了确保场自动装配使用@Autowired你需要通过注释的AddSchoolTest类运行与SpringJUnit4ClassRunner测试：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "classpath*:/path/to/applicationContext.xml" }) 
public class AddSchoolTest { 

    @Autowired 
    private UserManagementController controller; 

    @Test 
    public void testAddSchool() throws Exception { 

     ModelMap model = new ModelMap(); 
     HttpServletRequest request = new MockHttpServletRequest(); 
     Pricing pricing = new Pricing(); 
     String userName = "Laily"; 
     pricing.setName(userName); 
     //ModelAndView mav= controller.handleRequest(); 

     ModelAndView mav= controller.addschool(pricing, model,null, request); 
     //fail("Not yet implemented"); 
     assertNull(pricing); 
     assertFalse(model.isEmpty()); 
     Assert.assertEquals("addschool", mav.getViewName()); 
    } 

} 

确保@ContextConfiguration正确设置你的Spring配置文件的位置。

你可以尝试改变

ModelAndView mv = new ModelAndView(ADDSCHOOL); 

到 ModelAndView mv = new ModelAndView(addschool);或

ModelAndView mv = new ModelAndView(pricing); 

，因为它是在你的控制器动作@ModelAttribute("addschool") Pricing pricing 。

我不知道，但只可以看到它是否有效与否

感谢。

如果它是红色的，那么你的测试用例正在下降，你的catch块是空的，打印堆栈跟踪，看看有什么问题，例外情况是你的测试用例会失败。
