Multiple ExpectedException in MsTest

Question

How can I put multiple ExpectedExceptionin in a MSTest?

something like this

[ExpectedException(typeof(ArgumentException))]
[ExpectedException(typeof(NullReferenceException))]

because it shows me ExpectedException in double error

Answer 1

If you look at the documentation for ExpectedExceptionAttribute Class you would see that the attribute is not meant to be used multiple times on a method.

This attribute can be specified on a method. There can be only one instance of this attribute on a method.

To answer the follow up question

Should I run test on each exception separately?

Yes. Separate tests with separate expectations. You are in control of the test and should arrange them accordingly.

Sorry, you can't is the simple answer.
