Pex – Unit Testing of SharePoint Services that Rocks!

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 high code coverage. Pex also contains a stubbing framework, Moles, that allows to detour any .NET method to user-defined delegates, e.g., replace any call to the SharePoint Object Model by a user-defined delegate.
