mockito를 사용한 추상 익명 클래스 내에서 테스트 void 메서드

Question

추상 클래스 인스턴스 내부에있는 메서드를 테스트 할 수 없습니다. 나는 이미 여러 가지 방법을 시도해 왔으며 이것이 가능한지 알고 싶습니다. 추상 클래스의 내용은 아래 링크에서 볼 수 있습니다.

는 belows로는 JUnit을 나는 위의 이미지의 경우를 테스트하려고 않았다 Mockito의 테스트입니다.

@RunWith(MockitoJUnitRunner.class) 
public class PahoRxMqttCallbackTest { 

    @Test 
    public void whenConnectionLostOccurs() { 
    PahoRxMqttCallback rxMqttCallback = mock(PahoRxMqttCallback.class);

    PahoRxMqttException exception = new PahoRxMqttException(
     new MqttException(MqttException.REASON_CODE_CONNECTION_LOST));

    } 

    @Test

    assertThat(rxMqttCallback).isNotNull(); 

    IMqttDeliveryToken deliveryToken = mock(IMqttDeliveryToken.class); 
    assertThat(deliveryToken).isNotNull();

    //ArgumentCaptor<IMqttDeliveryToken> onDeliveryCompleteTokenArgumentCaptor = ArgumentCaptor.forClass(IMqttDeliveryToken.class); 
    ArgumentCaptor<RxMqttToken> onDeliveryCompleteRxTokenArgumentCaptor = ArgumentCaptor.forClass(RxMqttToken.class); 

    //rxMqttCallback.deliveryComplete(deliveryToken); 
    rxMqttCallback.deliveryComplete(rxMqttToken); 

    /*

    assertThat(onDeliveryCompleteRxTokenArgumentCaptor.getValue()).isExactlyInstanceOf(PahoRxMqttToken.class);

    String topic = "topic"; 
    MqttMessage message = new MqttMessage(); 

    ArgumentCaptor<String> onMessageArrivedTopicArgumentCaptor = ArgumentCaptor.forClass(String.class); 
    ArgumentCaptor<MqttMessage> onMessageArrivedMessageArgumentCaptor = ArgumentCaptor.forClass(MqttMessage.class);

    verify(rxMqttCallback).messageArrived(onMessageArrivedTopicArgumentCaptor.capture(), onMessageArrivedMessageArgumentCaptor.capture()); 

    assertThat(onMessageArrivedTopicArgumentCaptor.getValue()).isNotNull(); 
    assertThat(onMessageArrivedTopicArgumentCaptor.getValue()).isEqualTo(topic); 

    assertThat(onMessageArrivedMessageArgumentCaptor.getValue()).isNotNull(); 
    assertThat(onMessageArrivedMessageArgumentCaptor.getValue()).isEqualTo(message); 
    } 

} 

웹에서 검색 한 후에도 실제로 할 수 없었습니다. 그래서 도움을 주셔서 감사합니다.

업데이트 전 테스트를 수행하고 Jacoco이 표시했다고 모든 경고를 충당 할 수 있었다. 그러나이 경우 익명 클래스를 사용하는 대신 추상 클래스에 대한 구현을 작성해야했습니다. 다음 링크에서

업데이트 된 단위 테스트 볼 수 있듯이 :

Answer 1

당신은 클래스의 인스턴스를 결코를, 단지 클래스의 조롱.

PahoRxMqttCallback rxMqttCallback = mock(PahoRxMqttCallback.class); 

실물 크기의 모의 광고는 가짜 사본이 아닙니다.

대신 당신이

PahoRxMqttCallback rxMqttCallback = new PahoRxMqttCallback(); 

또는

PahoRxMqttCallback rxMqttCallback = spy(new PahoRxMqttCallback());
