java - Mockito: How to match any enum parameter

Question

I have this method declared like this

private Long doThings(MyEnum enum, Long otherParam); and this enum

public enum MyEnum{
  VAL_A,
  VAL_B,
  VAL_C
}

Question: How do I mock doThings() calls? I cannot match any MyEnum.

The following doesn't work:

Mockito.when(object.doThings(Matchers.any(), Matchers.anyLong()))
        .thenReturn(123L);

Answer 1

Matchers.any(Class) will do the trick:

Mockito.when(object.doThings(Matchers.any(MyEnum.class), Matchers.anyLong()))
    .thenReturn(123L);

null will be excluded with Matchers.any(Class). If you want to include null you must use the more generic Matchers.any().

As a side note: consider using Mockito static imports:

import static org.mockito.Matchers.*;
import static org.mockito.Mockito.*;

Mocking gets a lot shorter:

when(object.doThings(any(MyEnum.class), anyLong())).thenReturn(123L);
