Mockito抛出异常

Question

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

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

我试过这样的.我得到了以下异常.

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

您的方法返回一个布尔值,因此您应该模拟一个布尔响应.

你应该有这样的东西:

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

您可以在mockito中检查doThrow()doAnswer()doNothing()和doReturn()的用法,以获得更详细和简单的解释.

Answer 2

您不能doNothing使用非void方法，因为您需要返回某些内容或抛出异常。

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

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