Spring Boot Learning Sharing (4) - The Use of Spring Boot Unit Testing

Spring Boot uses unit tests (Controller and Shiro's tests)

---

1 Test
Controller spring boot integrates the plug-ins for web testing before spring mvc, and the annotations of its test classes are simplified as

@RunWith(SpringRunner.class)
@SpringBootTest
public class AppTest {
    // 模拟MVC对象，通过MockMvcBuilders.webAppContextSetup(this.wac).build()初始化。
    private MockMvc mockMvc;
    // 注入WebApplicationContext
    @Autowired
    private WebApplicationContext wac;    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }
}

The test class is written to simulate web interaction by calling the mockMvc method, for example

@Test
public void testGetUserList() throws Exception {
   MvcResult result = mockMvc.perform(get("/getAllUser"))
   .andReturn();// 返回执行请求的结果    
   System.out.println(result.getResponse().getContentAsString());
}

It is also possible to pass parameters. If you want to pass JSON data, you can use the JSON operation class to convert the data into JSON format.

@Test
public void testRegister() throws Exception {
     MvcResult result = mockMvc.perform(post("/UserRegister")
                .accept(MediaType.parseMediaType("application/json;charset=UTF-8"))
                .param("name", "1234")
                .param("password", "1234"))
                .andReturn();// 返回执行请求的结果
        System.out.println(result.getResponse().getContentAsString());
    }

When using, pay attention to the call of the get and post methods, otherwise an error will be reported during the test

Two Shiro tests

---

Personal opinion: mockMVC is not suitable for debugging shiro. The blogger cannot further verify the permissions after testing the login verification using shiro, and the annotations of shiro cannot be parsed. The filtering of shiro can only be achieved through the initial configuration. . . . , the only thing that can be tested is this function

---

In the case that there is no problem with the various configurations of shiro, if the following error occurs during the test

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'timestamp' cannot be found on object of type 'java.util.HashMap' - maybe not public?

There are three reasons, one may be that Shiro's filter has not been added to the test environment. The solution in this case is as follows:

        DefaultMockMvcBuilder builder = MockMvcBuilders.webAppContextSetup(wac);
        builder.addFilters((javax.servlet.Filter) wac.getBean("shiroFilter"));
        mockMvc = builder.build();

One of them shiroFilteris the bean name of the shiro filter,
and other is the permission verification problem of shiro. The default annotation in the test environment is lower than that configured directly on the bean side of the filter during initialization, which may cause the above error.
The last one That is, the get and post methods do not match, so pay attention when writing
