I was recently asked by someone on Twitter to describe my setup for writing tests against my Silverlight application. I thought I would write them down here in case others might find this information useful.
Testing Framework: A slightly modified version of NUnit that works with SIlverlight.
Mocking Framework: Moq 3.0 includes support for Silverlight. This is my favorite mocking framework, so I am happy that it now supports Silverlight.
Making testing easier: This is not specific to Silverlight testing, but I use ReSharper templates that I have customized to aid in writing tests quickly.
The MVVM Pattern: This is not a tool, but I the majority of my SIlverlight code would be un-testable if I didn’t know the MVVM pattern. I highly recommend using this pattern with Silverlight. None of the view code can be tested using NUnit, so testing the ViewModel is essential.
UI Automation: I am just starting to play with this. White is a layer on top of Microsoft’s UI Automation (UIA) framework. UIA is much to hard to use without a “helper” layer. It lets you run fully automated UI tests. I only want to use this to make sure my data bindings are correct. My unit tests are really the bulk of my testing efforts.
