mockito return value based on property of a parameter

Question

Normally when using mockito I will do something like

Mockito.when(myObject.myFunction(myParameter)).thenReturn(myResult);

Is it possible to do

Answer 1

In Java 8 it is even simpler than all of the above:

when(mockObject.myMethod(anyString()))
    .thenAnswer(invocation -> 
        invocation.getArgumentAt(0, String.class));
