[java] Mockito test a void method throws an exception

I have a method with a void return type. It can also throw a number of exceptions so I'd like to test those exceptions being thrown. All attempts have failed with the same reason:

The method when(T) in the type Stubber is not applicable for the arguments (void)

Any ideas how I can get the method to throw a specified exception?

doThrow(new Exception()).when(mockedObject.methodReturningVoid(...));

This question is related to java exception mocking mockito

The answer is


If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));
