How do you assert that a certain exception is thrown in JUnit 4 tests?

Question

How can I use JUnit4 idiomatically to test that some code throws an exception?

While I can certainly do something like this:

@Test
public void testFo         


        

Answer 1

You can also do this:

@Test
public void testFooThrowsIndexOutOfBoundsException() {
    try {
        foo.doStuff();
        assert false;
    } catch (IndexOutOfBoundsException e) {
        assert true;
    }
}
