Mockito How to mock and assert a thrown exception?

Question

I\'m using mockito in a junit test. How do you make an exception happen and then assert that it has (generic pseudo-code)

Answer 1

BDD Style Solution (Updated to Java 8)

Mockito alone is not the best solution for handling exceptions, use Mockito with Catch-Exception

Mockito + Catch-Exception + AssertJ

given(otherServiceMock.bar()).willThrow(new MyException());

when(() -> myService.foo());

then(caughtException()).isInstanceOf(MyException.class);

Sample code
