Question

我有以下控制器：

@PostMapping("/signup")
public ResponseEntity<?> registerUser(@Valid @RequestBody SignUpRequest signUpRequest) {
    if(userRepository.existsByUsername(signUpRequest.getUsername())) {
        return new ResponseEntity(new ApiResponse(false, "Username is already taken!"),
                HttpStatus.BAD_REQUEST);
    }

    if(userRepository.existsByEmail(signUpRequest.getEmail())) {
        return new ResponseEntity(new ApiResponse(false, "Email Address already in use!"),
                HttpStatus.BAD_REQUEST);
    }

    // Creating user's account
    User user = new User(signUpRequest.getName(), signUpRequest.getUsername(),
            signUpRequest.getEmail(), signUpRequest.getPassword());

    user.setPassword(passwordEncoder.encode(user.getPassword()));

    Role userRole = roleRepository.findByName(RoleName.ROLE_USER)
            .orElseThrow(() -> new AppException("User Role not set."));

    user.setRoles(Collections.singleton(userRole));

    User result = userRepository.save(user);

    URI location = ServletUriComponentsBuilder
            .fromCurrentContextPath().path("/api/users/{username}")
            .buildAndExpand(result.getUsername()).toUri();

    return ResponseEntity.created(location).body(new ApiResponse(true, "User registered successfully"));
}

在上面的代码中，我正在使用JPA存储库从数据库中获取角色名称，并将其用于我的用户（如果存在）。

我正在尝试使用以下测试对此进行测试：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = VlmSpringBootApplication.class)
@AutoConfigureMockMvc
public class AuthControllerTests
{
    @Autowired
    private AuthController authController;

    @MockBean
    private RoleRepository roleRepository;

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void contextLoads() {
        Assert.assertNotNull(authController);
    }

    @Test
    public void createUserTest() throws Exception {

        User newTestUser = new User();
        newTestUser.setName("testUserA");
        newTestUser.setUsername("testUserA");
        newTestUser.setEmail("testUserA@testing.com");
        newTestUser.setPassword("superSecretStuff");

        Role testRole = new Role();
        testRole.setName(RoleName.ROLE_USER);

        Optional<Role> optional = Optional.of(testRole);

        Set<Role> roles = Collections.EMPTY_SET;
        roles.add(optional.get());
        newTestUser.setRoles(roles);

        when(roleRepository.findByName(RoleName.ROLE_USER)).thenReturn(optional);

        Gson gson = new Gson();
        String json = gson.toJson(newTestUser);
        mockMvc.perform(put("/api/auth/signup")
                .contentType(MediaType.APPLICATION_JSON).content(json))
                .andExpect(status().isOk());
    }

运行此测试时，出现以下错误：

我所要做的就是在正在测试的代码中模拟回购调用以获取角色，然后从那里继续。

自己修复此问题！我需要做

@InjectMocks

而不是@Autowired。

在Spring Boot中使用MockMvc的测试中模拟JPA存储库？
