Rhino Mocks,MbUnit:检查对象是否已引发事件的最佳方法

我发现Phil Haack撰写了关于如何使用匿名委托测试事件的文章

这是代码,直接从他的博客中删除那些懒得点击的人:

[Test]
public void SettingValueRaisesEvent()
{
    bool eventRaised = false;
    Parameter param = new Parameter("num", "int", "1");
    param.ValueChanged += 
        delegate(object sender, ValueChangedEventArgs e)
        {
            Assert.AreEqual("42", e.NewValue);
            Assert.AreEqual("1", e.OldValue);
            Assert.AreEqual("num", e.ParameterName);
            eventRaised = true;
        };
    param.Value = "42"; //should fire event.

    Assert.IsTrue(eventRaised, "Event was not raised");
}
