Mockito拋出異常

Question

public interface ABC { 
     public boolean removeUser(String userId) throws OTPServiceException, RemoteException; 
} 

ABC abc= mock(ABC.class); 
doNothing().when(abc).removeUser(anyString()); 

我試過這樣。我得到了以下例外。

org.mockito.exceptions.base.MockitoException: 
Only void methods can doNothing()! 
Example of correct use of doNothing(): 
    doNothing(). 
    doThrow(new RuntimeException()) 
    .when(mock).someVoidMethod(); 
Above means: 
someVoidMethod() does nothing the 1st time but throws an exception the 2nd time is called 

Answer 1

你方法返回一個布爾值，所以你應該模擬一個布爾響應。

你應該有這樣的事情：

when(abc.removeUser(anyString())).thenReturn(true); 

您可以檢查Usages of doThrow() doAnswer() doNothing() and doReturn() in mockito獲得更詳細的，簡單的解釋。

Answer 2

你可以因爲你需要對非void方法不doNothing要麼返回的東西或拋出異常。

when(abc.removeUser(anyString())).thenReturn(true); 

when(abc.removeUser(anyString())).thenThrow(RuntimeException.class);
