Unit Testing Silverlight With SilverUnit

Download source code examples of using SilverUnit here.

There are many advantages for unit testing Silverlight with Typemock Isolator. These include shortening the development cycle, reducing the development costs, increasing code coverage, releasing a product with fewer bugs, providing good documentation and more…

Microsoft Silverlight runs with its own version of .Net runtime. Up until now, it was not possible to isolate Silverlight code in tests. But now, thanks to SilverUnit, built on top of Typemock Isolator, it is possible to test Silverlight with ease.

SilverUnit does not require that you run your tests inside the Silverlight runtime. You can run your regular NUnit or MSTest tests only in-memory. The CThru engine underneath SilverUnit takes care of intercepting and “skipping” all calls to the Silverlight runtime. SilverUnit does its part and mimics the missing pieces (Dependency Properties, RoutedEvents, and so on), so you wouldn’t need to write them yourself.

SilverUnit is the first implementation of CThru, targeted specifically at testing Silverlight applications. CThru is an AOP (Aspect Oriented-Programming) open source project based on a new Typemock Isolator feature set called “Open AOP” that allows you to intercept any call in a precompiled system (SharePoint, Silverlight, etc.) and change its behavior.

Unit Testing Silverlight Code Sample VB.NET

Below you can see a unit testing Silverlight code sample. This test sets dependency properties and checks what happens when an Invalid value is set on them. The next one uses two controls with each other.
