An example of how to use JUnit `@Rule` to test methods who are expected to thrown an exception.

MyClassTest.java

package sample;

import org.junit.*;
import org.junit.rules.ExpectedException;
import sample.*;

import static org.hamcrest.CoreMatchers.*;
import static org.hamcrest.MatcherAssert.assertThat;

public class MyClassTest {
    @Rule
    public ExpectedException exception = ExpectedException.none();
    
    @Test
    public void testNoExceptionsExpected() throws Exception {
        asserThat(new MyClass().thisWillWork(), notNullValue());
    }
    
    @Test
    public void testExpectedMyException() throws Exception {
        exception.expect(MyException.class);
        new MyClass().thisWillFail();
    }
}

Is the @Rule annotation new in junit4?
