Test presenter in ASP.NET Web Form

I am working on an ASP.NET WebForm application using MVP pattern. For every Web Form, there is a Presenter class associated to handle UI and Business logic. However, I had problem when writing unit tests for Presenters, since session values are used in presenters. And there is no HTTP context exists during execution of the unit test ( BTW I use nUnit ), making it is impossible to write unit test for presenters.

Anyone can explain how to unit test these presenters?

Thanks

Solution

  • you can either mock or stub out an IHttpContext and let your framework inject the real HttpContext or you can wrap the session, cookie, ... state behind some interfacing, or you could use "Moles" from Pex, the interfacing is explained here http://haacked.com/archive/2007/09/09/ihttpcontext-and-other-interfaces-for-your-duck-typing-benefit.aspx
