ExpectedException Assert

Question

I need to write a unit test for the next function and I saw I can use [ExpectedException]

this is the function to be tested.

public static T FailIfEnumIs         


        

Answer 1

You must use ExpectedException differently:

[TestMethod]
[ExpectedException(typeof(ArgumentOutOfRangeException))]
public void MyTestSomething() 

and then code your test so that the expected exception gets thrown.
