Question

我是编写测试用例的新手：

我的控制器如下：

 @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;
           }

我的junit测试用例是这样的：

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){

        }
    }

}

但我的问题是，即使我将删除“添加学校”并将其他东西显示为绿色，但如果我删除尝试和捕获，而不是在每种情况下都会给出红色。问题是什么。

完整堆栈跟踪就是这个

Answer 1

您可以尝试更改

ModelAndView mv = new ModelAndView(ADDSCHOOL);

要 ModelAndView mv = new ModelAndView(addschool);或

ModelAndView mv = new ModelAndView(pricing);

就像在@ModelAttribute("addschool") Pricing pricing中一样在你的控制器动作中。

我不确定但是能看出它是否有效

感谢。

Answer 2

如果它是红色然后您的测试用例正在下降，您的catch块为空，打印堆栈跟踪并查看问题是什么，例外情况下您的测试用例将失败。

Answer 3

正如pappu_kity所说，删除空的catch块会暴露出controller字段为空的事实 - 因此可能尚未自动装配。

要确保使用@Autowired自动装配该字段，您需要通过SpringJUnit4ClassRunner类注释AddSchoolTest来运行测试：

@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());
    }

}

确保为Spring配置文件的位置正确设置@ContextConfiguration。
