1.  About Me: Eric Hexter  Director of Austin.Net User Group  AspInsiders  Organized the 2007 Austin Code Camp  Build websites and web applications since 1996  Unit Testing since 2004  Test Infected since 2006

2.  What is Silverlight  Why do you need a whole session on unit testing?  Silverlight Runtime  Types of Tests  Unit Test Pattern  Testing Framework Choices  Code  Async  Tips & Tricks  Resources

3.  Silverlight 2.0  Rich Internet Application platform  It is a Web technology  Subset of the.Net Runtime  Runs cross platform – Windows/Linux/Mac  Runs cross browser – IE/Firefox/Safari  Silverlight 1.0 = Javascript  Silverlight 2.0 =.Net – C#,Vb.Net,dynamic languages….

4.  The standard solutions for unit testing do not apply.  The CLR is a subset of.Net  Currently no Mocking support  All networking is Async  The Test Framework can solve solutions which were previously solved by multiple solutions.. ie nUnit + Watir / Selenium

5.  Unit Test  Tests a single method for a single assertion  Integration Test  Test the interaction of multiple classes.  Can leave the process boundry. Make calls to webservices…ect.  Smoke Tests  Tests the happy path by pushing the UI to perform user based test cases.

6.  Arrange  Act  Assert  See Code Sample - UnitTestSample

7.  Silverlight Test Framework  Unit Tests – run all tests  Integration Tests  Smoke Tests  TestDriven.Net  Unit Tests – single test execution  nUnit (Silverlight Project Template)  Unit Tests  Some Integration Tests

8.  Show Project References  Special Project Templates  Test Framework Runner  Why Asynchronous Tests  Silverlight User Interfaces can be async.  Out of process calls are async.  Sample….

9.  Making the Asynchronous tests palatable  Easier to read… Easier to remember months later  Less clutter / easier to meet the 3As  A fluent interface wrapper..  Sample
