Moq: test to see if exception is thrown

/ Published in: C#
Save to your folder(s)
The ExpectedException section under [TestMethod] is where you tell Moq what type of exception your listening for. If that exception is thrown, then this test will pass and it will stop running all the code under the target.CalculateProvisionalPrice.

In case the exception isn't thrown, the Assert.Fail will throw an exception alerting you that the ArgumentNullException wasn't thrown.
