public interface Answer<T>
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() {
         public 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"));
