JUnit @Test expected annotation not working

Question

I\'ve got the following test:

@Test(expected = IllegalStateException.class)
public void testKey() {
    int key = 1;
    this.finder(key);
}

Answer 1

The problem was, that the class in which the test was nested was an extension of TestCase. Since this is JUnit 3 style, the annotation didn't work.

Now my test class is a class on its own.
