Mockito：实际上，与这个模拟的交互为零

Question

• 实际上我尝试了不同的方法，但测试用例每次都失败，我不确定我做错了什么。

• 我浏览了所有类似的问题&尝试了所有的方法，但仍然无法得到大部分。

• 但是我仍然收到以下错误。我还附上了代码供参考。

  eventListener.onLogin();
  ->在com.plivo.endpoint.login.TEndpointLoginTest.t2_endpoint_login_success_test（TEndpointLoginTest.java:65）
  
  事实上，与这个模拟的互动为零。
  
  

TEndpointLoginTest.java

@RunWith(MockitoJUnitRunner.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class TEndpointLoginTest {

    @Mock
    private TEventListener eventListener;

    private TEndpoint endpoint;

    @BeforeClass
    public static void create() {
    }

    @Before
    public void setUp() {
        MockitoAnnotations.openMocks(this);
        if (endpoint == null) {
            endpoint = TEndpoint.newInstance(eventListener);
        }
    }

    @Test
    public void t1_endpoint_isInitialized_test() {
        assertThat(endpoint).isNotNull();
    }

    // Login
    @Test
    public void t2_endpoint_login_success_test() {
        endpoint.login(1);
        verify(eventListener, timeout(1200)).onLogin();
    }

}

TEndpoint.java

public class TEndpoint {
    protected TEventListener eventListener;
    private TSipController sipController;

    public TEndpoint(TEventListener listener) {
        this.eventListener = listener;
        initLib();
    }

    public static TEndpoint newInstance(TEventListener eventListener) {
        TEndpoint endpoint = new TEndpoint(eventListener);
        return endpoint;
    }

    private void initLib() {
        sipController = TSipController.getInstance(this);
    }

    public void login(int flag) {
        if (flag == 1) {
            sipController.fireLogin();
        } else {
            sipController.fireLogOut();
        }
    }
}

TSipController.java

public class TSipController {
    private static TSipController controller;
    private final TEventListener eventListener;
    private final TEndpoint endpoint;

    public static TSipController getInstance(TEndpoint endpoint) {
        if (controller == null) {
            controller = new TSipController(endpoint);
        }
        return controller;
    }

    private TSipController(TEndpoint endpoint) {
        this.eventListener = endpoint.eventListener;
        this.endpoint = endpoint;
    }

    public void fireLogin(){
        new Handler(Looper.getMainLooper()).postDelayed(eventListener::onLogin, 1000);
    }

    public void fireLogOut(){
        new Handler(Looper.getMainLooper()).postDelayed(eventListener::onLogOut, 1000);
    }
}

TEventListener.java

public interface TEventListener {
    void onLogin();
    void onLogOut();
}
