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"));
