- 16. ...
- 17. Gains Unit Test
- 18. Integration Test
- 19. Regression Test
- 20. Code Coverage
- 21. ...
- 22. What a manager do? Define the problem
- 23. Break it down
- 26. Measure it
- 27. Bad smell(Can we be better)?
- 28. ...
- 29. What we do in Scrum? Define (and pickup) user story
- 30. Break story into tasks
- 31. Assign task to owner
- 33. Testing
- 34. Sprint review
- 35. What we do in code? Define the function
- 36. Break it down
- 37. Encapsulation
- 38. Black box
- 39. Test it
- 41. ...
- 42. What we do in Unit Test? Exactly describe use case (TDD?)
- 44. Focus on own "Unit"
- 46. Cover all public interfaces
- 47. What we do in Integration Test? Extractly describe use case
- 48. Use real external resource/interface
- 49. Focus on both business logic and accessbility between systems
- 50. Cover "own" public interface
- 51. A real case
- 52. A real case Unit Test and Integration Test are sharing same test code (business logic)
- 53. They have different configurations(IOC)
- 54. Not only "Happy pass", remember cover exception
- 55. Code review and commit Developer Run regression test suite (UT + IT)
- 56. Run FindBugs
- 57. Fix bugs
- 59. Wait until review is finished
- 60. Commit Reviewer Download patch
- 61. Run UT suite
- 62. Run FindBugs
- 63. Review code
- 65. Finish Review
- 66. Can we do better? - Eclipse Plugins FindBugs
- 68. Eclemma code coverage tools
- 72. Google CodePro
- 74. Version One
- 76. Encapsulate external dependencies Create Proxy, Delegate or Wrapper classes to encapsulate external dependencies
- 77. Implement the interface which represent our own requirement by this encapsulator.
- 78. While external interface changes, our own interface will not changes, but the encapsulator changes.
- 79. As a result, the client code which calls our own interface need not any changes.
- 80. FindBugs
- 81. FindBugs
- 82. Eclemma - Code Coverage
- 83. Eclemma - Code Coverage Help us know what has not been coverred
- 84. Help us find bugs
- 85. The higher coverage we have, the safer when we do refactory or add new feature
- 87. Google CodePro – audit code
- 88. Google CodePro – dependencies
- 89. Google CodePro - dependencies
- 90. Google CodePro - dependencies Current: Tight couplings with external dependencies
- 91. Google CodePro - dependencies Better: Encapsulate external dependency
- 92. VersionOne Avoid missing tasks
- 93. Any comments?
- 94. Thank you!
