Unit test Springboot MockMvc returns 403 Forbidden

Question

I wrote one unit test that tests UsersController. UsersControllerTest.findUser is working fine, but UsersControllerTest.insertGetModifyDelete it doesn't.

In the log of the test I can see that the POST request doesn't match any method of UsersController, but I don't understand why. Could you help me with this, please?.

This is my rest java class:

@RestController
@RequestMapping("/users")
public class UsersController {

    private final UsersService usersService;

    @Autowired
    public UsersController(UsersService usersService) {
        this.usersService = usersService;
    }

    @GetMapping(value="/{email}", produces="application/json")
    public User get(@PathVariable @Email String email) {
        return usersService.findByEmail(email);
    }

    @PostMapping(consumes="application/json", produces="application/json")
    @ResponseBody
    public ResponseEntity<String> insert(@RequestBody @Valid User user){
        usersService.insert(user);
        return ResponseEntity.ok(user.getEmail());
    }

    @DeleteMapping(value="/{email}", consumes="application/json", produces="application/json")
    public ResponseEntity<String> delete(@PathVariable @Email String email) {
        usersService.delete(email);
        return ResponseEntity.ok(email);
    }

    @PutMapping(value="/{email}", consumes="application/json", produces="application/json")
    public ResponseEntity<User> update(@PathVariable @Email String email, @RequestBody @Valid User user) {
        usersService.update(email, user);
        return ResponseEntity.ok(user);
    }

}

I have one test with 2 methods. One is working returning http code 200, but the other returns 403.

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@WithMockUser(username = "user", roles = "USER")
public class UsersControllerTest {


    @Autowired
    private MockMvc mockMvc;

    @Test
    public void findUser() throws Exception {
        mockMvc.perform(get("/users/{email}", new Object[] {"[email protected]"})).andExpect(status().isOk()).andExpect(jsonPath("$.email", equalTo("[email protected]"))).andExpect(jsonPath("$.userName", equalTo("boy")));
    }

    @Test
    public void insertGetModifyDelete() throws Exception {
        User user = new User("userName", "[email protected]");
        ObjectMapper mapper = new ObjectMapper();
        String json = mapper.writeValueAsString(user);
        mockMvc.perform(post("/users").content(json).contentType(MediaType.APPLICATION_JSON).accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
        mockMvc.perform(put("/users/{email}", new Object[] {user.getEmail()}).content(json)).andDo(print()).andExpect(status().isOk());
        mockMvc.perform(delete("/users/{email}", new Object[] {user.getEmail()}).content(json)).andDo(print()).andExpect(status().isOk());
    }

}

And this is the output of the test:

You can try to debug this program.i think probleam is happend in "mockMvc" object is not autowired.mockMvc object should load from WebApplicationContext in before program run.

@Autowired
private WebApplicationContext webApplicationContext

@Before()
public void setup()
{
    //Init MockMvc Object and build
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
