問題描述

我有界面

Interface MyInterface {
  myMethodToBeVerified (String, String);
}

接口的實現是

class MyClassToBeTested implements MyInterface {
   myMethodToBeVerified(String, String) {
    …….
   }
}

我還有一門課

class MyClass {
    MyInterface myObj = new MyClassToBeTested();
    public void abc(){
         myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }
}

我正在嘗試為 MyClass 編寫 JUnit.我已經完成了

I am trying to write JUnit for MyClass. I have done

class MyClassTest {
    MyClass myClass = new MyClass();
  
    @Mock
    MyInterface myInterface;

    testAbc(){
         myClass.abc();
         verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
    }
}

但是我得到 mockito 想要但沒有被調用，實際上在驗證調用時與這個 mock 的交互為零.

誰能提出一些解決方案.

can anyone suggest some solutions.

推薦答案

你需要在你正在測試的類中注入 mock.目前，您正在與真實對象進行交互，而不是與模擬對象進行交互.您可以通過以下方式修復代碼:

You need to inject mock inside the class you're testing. At the moment you're interacting with the real object, not with the mock one. You can fix the code in a following way:

void testAbc(){
     myClass.myObj = myInteface;
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}

雖然將所有初始化代碼提取到 @Before

although it would be a wiser choice to extract all initialization code into @Before

@Before
void setUp(){
     myClass = new myClass();
     myClass.myObj = myInteface;
}

@Test
void testAbc(){
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}
