4. ◊Building Quality into the process –Real time identification of quality issues Automation –Using the right tools and techniques 21 st Century Quality Practices

5. Benefits* Assuming 100 defects in 10,000 lines of code 1.Traditional testing finds a defect in about 10 hours 2.Manual code inspections find a defect in 1 hour 3.Automated testing finds a defect every 6 minutes *Sources: Grant, T.

8. First Do This 1. Version Control –What: Repository to persist and track version of code and artifacts –Effort: Low –Sample Tools: Traditional – TFS (MS), Subversion Distributed Version Control (branching and merging) - Git, Mercurial

9. First Do This 2. Build Automation –What: One click or one command launch of build process –Effort: Low –Sample Tools: Microsoft – MSBuild, Powershell Java/Others – Ant, Gradle, Maven

10. First Do This 3. Automated Unit Testing –What: An automated stand alone test that test a single unit of the code. –Effort: Medium –Sample Tools: Unit test tools: JUnit (Java), NUnit (MS), MS Test (MS) Advanced tools: Moq, Fluent Assertions

11. First Do This 4. Continuous Integration –What: Provides frequent verification and notification of changes to the code and application –Effort: Medium –Sample Tools: Jenkins, Hudson, TFS (MS), TeamCity

12. Continuous Integration Build #1 compile unit test integration test package deploy/run acceptance test analyze code Build Report Version Control change #1 change #2 Build Server Build #2 compile unit test integration test package deploy/run acceptance test analyze code Build Report Email Failed Build

13. Continuous Integration ◊CI involves: –Frequent code check-ins –Regularly scheduled, automated builds –Automated tests –Immediate feedback to developers detailing any build errors or failed tests ◊Benefit: –Developers know immediately upon check-in if their code works and if any other application features were broken as a result

14. CI Effect on Schedule Code PhaseQA PhaseCode PhaseQA Phase Code Phase Code + Test Phase Schedule Release 1 Release 2 Original Plan Reality With CI

15. Benefits of Continuous Integration ◊Avoids last-minute chaos at release dates ◊Early warnings of broken code ◊Early warning of conflicting changes ◊Immediate testing of all changes ◊High availability of a "current" build for testing, demo, or release purposes

17. Next Do This 5) Static Code Analysis –What: Checks for coding standards and code quality –Effort: Low –Sample Tools: Visual Studio Code Analysis, FindBugs (Java), PMD, Cobertura, Sonar, CheckStyle

18. Code Quality

19. Next Do This 6) Dependency Management –What: Manages 3 rd party components and ensure we have the latest / correct version these components –Effort: Low –Sample Tools: Gradle, NuGet

21. Then Do This 7. Automated Integration Testing –What: Testing interaction between multiple components to ensure our component dependencies don’t break –Effort: Medium to High –Sample Tools: DBUnit (Java), NDBUnit (MS)

22. Then Do This 8. Automated Acceptance Testing –What: Automated testing to ensure the systems meets business needs –Effort: High –Sample Tools: SpecFlow, Cucumber, FitNess –For Browser Testing: Selenium, WatiN

23. Automated Tests ◊Automated tests involves: –Unit tests: Testing of smallest possible piece of code that can operate in isolation –Integration tests: Testing interaction between multiple components –Acceptance tests: Testing complete segments of a system to ensure it meets the business needs ◊Benefits –Enables rapid discovery of root cause –Reduces defect rate –Saves time in system test –Ensures testing starts early in cycle –Provides for a free regression testing suite

24. Testing Quadrant Functional Tests Acceptance Tests Unit Tests Component Tests System Tests Showcases Exploratory Tests Usability Tests Performance Tests Security Tests The Team The Product Functionality The System from Brian Marick

25. Then Do This 8. Automated Deployment –What: Push button deployment capabilities –Effort: High –Sample Tools: FluentMigrator, Puppet, Octopus
