JUnit @Test expected annotation not working

I\'ve got the following test:

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

Answer 1

i tried this one, and work perfectly as expected.

public class SampleClassTest {
    @Test(expected = ArithmeticException.class )
    public void lost(){
        this.lost(0);
    }
    private void lost(int i) throws ArithmeticException {
        System.out.println(3/i);
    }
}

also ensure that junit4 is added as dependancy, @ (annotations) are new feature in junit 4.
