Download as PPT, PDF0 likes1,035 views
The document discusses automated unit testing and test-driven development (TDD) specifically for Silverlight on Windows Phone 7. It introduces key concepts such as the Model-View-ViewModel (MVVM) design pattern and emphasizes the importance of writing unit tests before coding to ensure software flexibility and maintainability. The presentation also includes references and resources for further reading on both MVVM and TDD.
Automated Unit Testing in Silverlight for Windows Phone 7
- 1. Automated Unit Testing with Silverlight for Windows Phone 7 Jacinto Limjap, Jr. Microsoft MVP for C# Senior Applications Developer, FBM e-Services
- 2. Agenda Automated unit testing and Test Driven Development MVVM – an overview Putting it all together using Silverlight for Windows Phone 7
- 3. Any mobile developers in the house? What do you use in terms of frameworks/patterns/unit testing?
- 4. AUTOMATED UNIT TESTING & TDD An introduction
- 5. What is Test Driven Development? Using unit tests to design software Allows change in code without fear of (inadvertently ) changing functionality Produces loosely coupled objects and methods with single responsibilities
- 6. What is Test Driven Development? Unit tests are just side effects: main point is DESIGN Write tests first, code later (?!)
- 7. What is Test Driven Development NOT? Substitute for QA testing Necessarily means successful project Silver bullet
- 8. TDD Mindset
- 9. Writing Tests Think about how you want to express your code and intentions Think about inputs, and intended output Separate small, isolated areas of functionality
- 10. Issues Unit tests should come BEFORE code Unit tests should NOT depend on presence or absence or external dependencies (e.g., storage, database, internet connection) How to solve this: Mocks, stubs and fakes
- 11. Do we really have to do test first?
- 12. MVVM The Model View ViewModel Pattern
- 13. Model-View-ViewModel Introduced in 2005 by John Gossman Originally designed for Windows Presentation Foundation (WPF) applications Designed in response to attempts to use Model-View-Controller (MVC) in WPF
- 14. Model-View-ViewModel Model – class or data representation of object you are using within your application View – the part of your application representing the user interface ViewModel – class or data representation of an object or combination of objects, as seen in the View
- 15. Model-View-ViewModel View (XAML) View Model Model Data Binding
- 16. So why is MVVM important?
