  1. Test Driven Development in the .Net Framework Sam Lee Mayur Mehta Jaymeen Shah McCoy College of Business Administration Texas State University-San Marcos

  2. Outline • Test Driven Development • Unit Testing & Visual Studio .Net 2008 • Nunit • ADO.Net Entity Framework • Conclusion

  3. Test Driven Development (TDD) • Packaged software • A powerful global industry • Intense time-to-market pressures • The need to always adapt software in progress to new functionality • TDD: unit test cases are written for the implementation of any new functionality

  4. TDD Advantages • Flexibly change the behavior of one part of the system without risking side effects in other parts. • Delivers software in smaller units that are less complex. • Effectively captures requirements such that development tools can be integrated to continue to improve system quality.

  5. TDD in Visual Studio .Net 2008 • Nunit • Free and open software • A unit-testing framework for all .Net languages • ADO.Net Entity Framework • Facilitate the persistence of data. • Abstract the structure of the data into a more business-friendly manner (based on object-oriented models)

  6. Demo: Nunit

  7. Demo: Entity Framework

  8. Model Driven Architecture (MDA) • The Entity Framework facilitates the construction of a MDA • MDA Models (Conn & Forrester, 2006) • Platform independent models (like UML class diagram) • Platform specific models (.Net framework & code libraries) • Transformation models (OR mapping & XML files)

  9. Conclusion • The classes that access databases can be quickly built and updated using the utilities of ADO.Net Entity Framework. • Develop unit test cases to manage the change of entity models. • Convergence of two development methodologies: TDD and MDA.
