* Generic interface to be used for configuring mock's answer.
* Answer specifies an action that is executed and a return value that is returned when you interact with the mock.
*
* Example of stubbing a mock with custom answer:
*
*
* when(mock.someMethod(anyString())).thenAnswer(new Answer() {
* Object answer(InvocationOnMock invocation) {
* Object[] args = invocation.getArguments();
* Object mock = invocation.getMock();
* return "called with arguments: " + Arrays.toString(args);
* }
* });
*
* //Following prints "called with arguments: [foo]"
* System.out.println(mock.someMethod("foo"));
*
*
* @param the type to return.
