  10. Sin #7: Separation of Requirements & Tests Req Spec Tests

  11. Penance • Create an executable specification: Spec == Tests • Use concrete examples to specify requierements • Analysts and Testers become best friends! • Acceptance Test Driven Development (ATDD, BDD) • Cucumber, FIT, Fitnesse, Selenium • Other tools??? • INVEST in user stories • Independent, Negotiable, Valuable, Estimable, Small, Testable • Include testing in the Definition of Done for stories & sprints • Expand your skills

  12. Sin #6: Testing is one sprint behind Code sprint 1 Code sprint 2 Code sprint 3 Code sprint 4 Test Sprint 1 Test Sprint 2 Test Sprint 3 Test Sprint 4

  13. Penance • Include testing in the Definition of Done for stories & sprints • Smaller backlog items & user stories • http://www.richardlawrence.info/2009/10/28/patterns-for-splitting-user-stories/ • Testers define & create tests at the start of each story/sprint • Automated testing / TDD / ATDD / BDD

  14. Sin #5: Unbalanced Testing Quadrants

  15. Penance • Include the appropriate testing quadrants in the Definition of Done for stories, sprints, and releases. • Have a balanced testing plan as part of release planning • Create backlog items for appropriate testing activities, e.g. –ility testing. • Get management commitment to support effort needed to “catch up” on test automation; show the ROI on automation. • Get real users & stakeholders to participate in acceptance testing – early and often.

  16. Sin #4: Ignoring Test Failures

  17. Penance • Discipline: stop the line whenever the CI build & tests fail • Invest in making automated tests robust • Create incentives for team members to have clean check-ins; friendly competition? • Take metrics: reward people for improving quality and automated test coverage

  18. Sin #3: Lack of TDD & CI

  19. Penance • Commit as a team to doing TDD and CI • Discipline: keep it going • Expand your skills • Invest in infrastructure, tools, training. Show the ROI. • Keep metrics to measure resulting quality improvements

  20. Sin #2: Separate QA Team Dev Dev Dev Dev Dev Dev QA QA QA QA QA QA

  21. Penance • Form cross-functional teams including QA • Co-located teams: same room • Do a pilot project with QA dedicated to the team; keep metrics to demonstrate the results. • Keep QA fully involved with the team: planning, implementing stories, demos, retrospectives • Whole-team responsibility for product quality

  22. Sin #1: WaterScrumming Analysis sprint Analysis sprint Code sprint Code sprint Code sprint Test sprint Test sprint Test sprint

  23. Penance • Form cross-functional teams including QA & analysts • Include testing in the Definition of Done for stories & sprints • INVEST in user stories • Independent, Negotiable, Valuable, Estimable, Small, Testable • http://www.richardlawrence.info/2009/10/28/patterns-for-splitting-user-stories/ • Testers define & create tests at the start of each story/sprint • TDD / ATDD / BDD • Allow one hardening sprint before release with all hands on deck testing
