SharePoint Services are challenging for unit testing because it is not possible to execute the SharePoint Service without being connected to a live SharePoint site. For that reason, most of the unit tests written for SharePoint are actually integration tests as they need a live system to run. In this session, we show how to use Pex, an automated test generation tool for .NET, to test SharePoint Services in isolation. From a parameterized unit test, Pex generates a suite of closed unit tests with …

In this episode we are going to take at how to use Pex and Moles for .Net. Unit testing is great, but most free isolation frameworks require that your mocks implement an interface. But what do you do when the class you are trying to mock is static or sealed with no interface. If you can’t modify the class then your unit testing efforts are usually stuck. Moles, the new free isolation framework from Microsoft, supports mocking almost any CLR based class (including sealed and static classes).
