I have a problem with throw InterruptedException. Part of my source:

    Future<Object> future = mock(Future.class);
    when(future.get(any(), any())).thenThrow(new InterruptedException());

But I get java.lang.NullPointerException on the second line, What's wrong with my code? I want to throw InterruptedException when I call get method

Have you used a Debugger? – Jens Mar 23 '17 at 14:39

`Mockito#any` returns `null`. `Future#get` expects a `long`. During the unboxing conversion, the `NullPointerException` is thrown. You could fix this with `any(Long.class)`, where it will return a non-null default value for the `Long` type. – Sotirios Delimanolis Mar 23 '17 at 14:40
thanks a lot! I change to anyLong() and it works – mystdeim Mar 23 '17 at 14:42
