Question

How to throw exception using PowerMock/PowerMockito/Mockito when a call to void method is made? Since the method is a void method so Mockito is not showing the option to throw exception. How can I go about it?

As explained in the documentation :

5. Stubbing void methods with exceptions

doThrow(new RuntimeException()).when(mockedList).clear();

//following throws RuntimeException:
mockedList.clear();
