java-即使未引发异常,JMock也会导致JUnit ExpectedException通过

当我将JMock与JUnit ExpectedException一起使用时,即使未引发异常,测试似乎也可以通过.例如,下面的测试应该失败.但是,如果我取消对两条注释行的注释,则它会通过.难道我做错了什么？这两个组件之间是否存在不兼容？

//@RunWith(JMock.class)
public class JUnitJMockTest {

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

    //Mockery context = new JUnit4Mockery();

    @Test
    public void test() {

        exception.expect(NullPointerException.class);

    }

}

解决方法:

我认为您可能会发现this page有用.引用它：

Beware though that if you combine the rule with certain @RunWith classes, you may get a false positive. Specifically, if you were to run with a class that extends JUnit4ClassRunner in the above example, the test would no longer fail. You’d get a false positive.

For example, if you’re using a version of JMock prior to 2.6.0 and use @RunWith(JMock.class) you’ll encounter this. Older versions of the JMock.class extend JUnit4ClassRunner and JUnit4ClassRunner ignores rules. The newer BlockJUnit4ClassRunner supports rules and JMock post 2.6.0 extend this in JMock.class.

简而言之,听起来您可能正在使用2.6.0之前的JMock版本,并且更新可能解决了您的问题.
