使用NUnit Assert.Throws方法还是ExpectedException属性？ [英] Use NUnit Assert.Throws method or ExpectedException attribute?

问题描述

我发现这些似乎是测试异常的两种主要方法：

I have discovered that these seem to be the two main ways of testing for exceptions:

Assert.Throws<Exception>(()=>MethodThatThrows());

[ExpectedException(typeof(Exception))]

其中哪些会最好？一个提供其他优点吗？还是仅仅是个人喜好问题？

Which of these would be best? Does one offer advantages over the other? Or is it simply a matter of personal preference?

推荐答案

第一个允许您通过多次调用测试多个异常：

The first allows you to test for more than one exception, with multiple calls:

Assert.Throws(()=>MethodThatThrows());
Assert.Throws(()=>Method2ThatThrows());

第二个只允许您为每个测试功能测试一个异常。

The second only allows you to test for one exception per test function.
