ExpectedException消息参数不起作用！ [英] ExpectedException message parameter does not work!

问题描述

以下测试不会失败。我错过了什么吗？

The following test does not fail. Am I missing something?

        [TestMethod]
        [ExpectedException( typeof( System.ArgumentException), "This is the WRONG exception message.")]
        public void ExpectedExceptionDoesntDetectWrongMessage()
        {
            ThrowException();
        }

        private void ThrowException()
        {
            throw new System.ArgumentException("This is the exception message.");
        }

推荐答案

为什么你会期望它失败？

从我所看到的，它抛出了预期的异常。

请注意，ExpectedException构造函数的第二个参数是无关的抛出异常。相反，它与Assert.IsTrue相同，这意味着如果出现问题（您没有获得例外异常），它将出现在测试结果中。那是你在看什么？

希望这会有所帮助。

Why would you expect this to fail?

From what I can see, it throws the expected exception.

Note that the second parameter of the ExpectedException constructor is NOT related to the thrown exception. Rather, it is the same as with Assert.IsTrue meaning that it  is the text that will appear in the test results if there is a problem (you don't get  the excepted exception). Is that what you were looking at?

Hope this helps.
