If you're using JUnit and you expect a test to throw a specific exception, do this:

@Test(expected = MyException.class)
public throwsExceptionWhenPassedAnIllegalValue() {
   [...]
}

If you're using TestNG, similar syntax:

@Test(expectedExceptions = MyException.class)
public void throwsExceptionWhenPassedAnIllegalValue() {
    [...]
}

If the exception that you're expecting is not thrown, these test methods will fail.
