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

If you want to test the exception message as well you can use JUnit's ExpectedException with Mockito:

@Rule
public ExpectedException expectedException = ExpectedException.none();

@Test
public void testExceptionMessage() throws Exception {
    expectedException.expect(AnyException.class);
    expectedException.expectMessage("The expected message");

    given(foo.bar()).willThrow(new AnyException("The expected message"));
}
