8. Test Driven Development Jim Newkirk

9. TDD Tenants Never write a single line of code unless you have a failing unit test Eliminate Duplication

10. Test List Task Based 4-8 hour duration 15-20 minute exercise at beginning Brainstorm a list of unit tests Do not get hung up on completeness, you can always add more later Describes completion requirements

11. Red/Green/Refactor Write a test for new capability Start Compile Fix compile errors Run the test And see it fail Write the code Run the test And see it pass Refactor as needed

12. Test Driven Development (TDD)

13. Recap Integrate testing into the development process Testability is a primary motivation during development The Visual Studio Team System provides an ideal environment for doing Test Driven Development

16. Code Coverage How effective are my unit tests? Am I done testing? Am I executing all the relevant parts of my application?

17. Code Coverage void PurchaseItem(int itemID) { if (itemID == 0) { throw new Exception(); } else { ProcessOrder(itemID); } UnitTest() { PurchaseItem(1); }

18. { if (itemID == 0) { throw new Exception(); } else { ProcessOrder(itemID); } Code Coverage UnitTest() { PurchaseItem(1); } void PurchaseItem(int itemID)

19. { throw new Exception(); } else { ProcessOrder(itemID); } void PurchaseItem(int itemID) if (itemID == 0) Code Coverage UnitTest() { PurchaseItem(1); }

20. { throw new Exception(); } { ProcessOrder(itemID); } void PurchaseItem(int itemID) if (itemID == 0) Code Coverage UnitTest() { PurchaseItem(1); } else

21. { throw new Exception(); } { ProcessOrder(itemID); } void PurchaseItem(int itemID) if (itemID == 0) Code Coverage UnitTest() { PurchaseItem(1); } else ProcessOrder(itemID);

22. { throw new Exception(); } { ProcessOrder(itemID); } void PurchaseItem(int itemID) if (itemID == 0) Code Coverage UnitTest() { PurchaseItem(1); } else ProcessOrder(itemID); throw new Exception();

30. Static Code Analysis Bad code is syntactically correct Different naming conventions Manual code reviews can be inconsistent

31. Static Code Analysis Defects Security Performance Design Policy String path = “”; for (int i = 0; i < 100; i++) { path += “Value”; } return path;

34. Static Code Analysis Don’t call String.Concat inside of loops Prefer StringBuilder String path = “”; for (int i = 0; i < 100; i++) { path += “Value”; } return path; for (int i = 0; i < 100; i++) { path.Append(Value”); } return path.ToString();

35. Visual Studio Team System Static Code Analysis

36. Catch bugs at their source Capable of complex analysis Leverages lessons learned Turn habit into ‘rules’

37. Application Verifier ‘Works on my machine’ ‘It used to work’ Runtime issues

39. Visual Studio Team System Application Verifier

40. Catch critical errors at runtime Handle/Heap verification issues ‘Breaks’ into Visual Studio Team System at the source of the problem

41. Code Profiler Constant hardware updates Poor end-user experience Low throughput of transactions
