[@talishboy][¥20]怎么利用 JUnit 来测试一个方法的异常？

@Test(expected= IndexOutOfBoundsException.class)
public void empty() {

   new ArrayList<Object>().get(0);  

}

或者

@Rule
public ExpectedException thrown = ExpectedException.none();

@Test
public void shouldTestExceptionMessage() throws IndexOutOfBoundsException {

    List<Object> list = new ArrayList<Object>();
    thrown.expect(IndexOutOfBoundsException.class);
    thrown.expectMessage("Index: 0, Size: 0");
    list.get(0); // execution will never get past this line  

}
