模拟通过 JSON 发布添加用户的控制器

Question

我正在尝试创建一个模拟控制器，但我不断收到捕获参数的错误。它说想要但没有调用。我仍然对 Mockito 和 Junit 以及它应该如何正常工作感到困惑。

控制器模拟

@Test
public void testAddUserController() throws Exception {
    JSONArray userArray = new JSONArray();
    JSONObject jsonObject = new JSONObject();
        jsonObject.put("username", "User 1");
        jsonObject.put("email", "[e-mail]");
        jsonObject.put("password", "password123");
        jsonObject.put("address", "Address 1");
        jsonObject.put("age", 12);
    userArray.put(jsonObject);
    mockMvc.perform(MockMvcRequestBuilders.post(BASE_URL + "/users").content(toString()).contentType(MediaType.APPLICATION_JSON_UTF8));
    Mockito.verify(userService, Mockito.times(1))
            .addUser(userCaptor.capture(), emailCaptor.capture(), passwordCaptor.capture(), addressCaptor.capture(), ageCaptor.capture());
    Assert.assertEquals("User 1", userCaptor.getValue());
    Assert.assertEquals("[e-mail]", emailCaptor.getValue());
    Assert.assertEquals("password123", passwordCaptor.getValue());
    Assert.assertEquals("Address 1", addressCaptor.getValue());
    Assert.assertEquals("12", ageCaptor.getValue());
}

用户服务

boolean addUser(String username, String email, String password, String address, Integer age);

UserServiceImpl

@Override
public boolean addUser(String username, String email, String password, String address, Integer age) {
    Optional<User> user = userRepository.findByUsernameAndEmail(username, email);
    if (!user.isPresent()) {
        User user1 = new User();
        user1.setUsername(username);
        user1.setEmail(email);
        user1.setPassword(password);
        user1.setAddress(address);
        user1.setAge(age);
        user1.setIsActive(true);
        userRepository.save(user1);
        return true;
    } else {
        return false;
    }
}

通过

@Test编写一个junit测试，并使用Mockito来模拟HttpResponse

InputStream jsonResponse = createJsonResponse();   
Mockito.when(mHttpClientMock.execute(Mockito.isA(HttpPost.class))).thenReturn(mHttpResponseMock);
    Mockito.when(mHttpResponseMock.getStatusLine()).thenReturn(mStatusLineMock);
    Mockito.when(mStatusLineMock.getStatusCode()).thenReturn(HttpStatus.SC_OK);
    Mockito.when(mHttpResponseMock.getEntity()).thenReturn(mHttpEntityMock);
    Mockito.when(mHttpEntityMock.getContent()).thenReturn(jsonResponse);
