Generic interface to be used for configuring mock's answer for a two argument invocation that returns nothing.
Answer specifies an action that is executed when you interact with the mock.
Example of stubbing a mock with this custom answer:
import static org.mockito.AdditionalAnswers.answerVoid;
doAnswer(answerVoid(
new VoidAnswer2<String, Integer>() {
public void answer(String msg, Integer count) throws Exception {
throw new Exception(String.format(msg, count));
}
})).when(mock).someMethod(anyString(), anyInt());
//Following will raise an exception with the message "boom 3"
mock.someMethod("boom %d", 3);
