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

  3. What is Silverlight • 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. Why a session on unit testing? • 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.. ienUnit + Watir/ Selenium

  5. Types of Tests • 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. Unit Test Pattern – The 3-As • Arrange • Act • Assert • See Code Sample - UnitTestSample

  7. Testing Framework Choices • 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. Using Test Framework • 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. Tips and Tricks • 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
