In the latest snapshot build of JUnit 4.7, we’ve re-implemented expected exceptions using Interceptors. Share and Enjoy!

	public static class HasExpectedException {
		@Interceptor
		public ExpectedException thrown= new ExpectedException();

		@Test
		public void throwsNothing() {

		}

		@Test
		public void throwsNullPointerException() {
			thrown.expect(NullPointerException.class);
			throw new NullPointerException();
		}

		@Test
		public void throwsNullPointerExceptionWithMessage() {
			thrown.expect(NullPointerException.class);
			thrown.expectMessage("happened?");
			throw new NullPointerException("What happened?");
		}
	}
