Can I access SessionState from within an NUnit test?

Question

One of my methods in an NUnit test checks a Session-State variable :

if (Sesssion[variableName] == null) ...

and the NUnit test is failing with err:

System.Web.HttpException: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration.

I tried taking the test method out of a class library and putting it into the codebehind cs of an aspx page that set EnableSessionState="True" in the aspx page directive. Added a web config with sessionState mode = "InProc" in the web config, then tried < pages enableSessionState ="true"/> in the web.config.

Nunit tests still failed on the session state action.

Do I have to mock these out?

Answer 1

I don't believe you can access Session from your unit tests without mocking it.
