  • 1. Testing Lessons From the Rolling StonesSimon Morley Let’s Test 2012 @YorkyAbroad
  • 2. What’s the most significant part of testing? I claim, it is: Communication Communication Communication
  • 3. But, not just any type of communication..... CongruentConway Heuristic Latin defn Weinberg
  • 4. Q:How can the rolling stoneshelp me do better testing? And get here Not here
  • 5. Playing with fire
  • 6. Playing with fireContext-free reportingContext-free requests
  • 7. Context-free reporting gets in “it works” the way of good testing!“it doesn’t work” “we ran lots of tests” “we found lots of bugs”
  • 8. Context-free reporting gets in “it works” the way of good testing!“it doesn’t work” “we ran lots of tests” “we found lots of bugs” Context-free “just test...” requests can get in the way of good testers. “the feature cannot be used...”
  • 9. Case Example report c.2009 Test Case Stats Trouble Reports Pass 1020 100,00% Prio A 0 Fail 0 0% Prio B 0 Not Started 0 0% Prio C 0Only one problem/concern observed: “We have to cope with >30% regression failures with each run… that means 3-4 re-runs at least before we are having “stable” results… ”
  • 10. Traps visible1. Test case counting self-herding2. Bug report counting3. Silent evidence confirmatory testing
  • 11. Countering such traps #1Stop talking only in numbers Get qualitative Use numbers as a footnote - not as a headline Ask for qualitative information
  • 12. Countering such traps #2Silent evidence - report to the whole context E What’s excluded? N What was not considered N What was not covered
  • 13. Nervous Breakdown
  • 14. “Why did you miss that bug?” “Why is testing taking so long?” “we are delayed due to the X testing activity... again” Taylorism in Testing Symptoms of one-sided communication or a need for test brand-building
  • 15. Traps visibleLimited Framing Self-herdingLack of Context awarenessLack of Systems Thinking (Linear Trap)
  • 16. Avoiding “Nervous Breakdowns”Frame + context awareness poor testing? missed tests? poor assignments? poor communication? communication raise education awareness brand building
  • 17. Avoiding “Nervous Breakdowns”Linear traps Beware of Silent Evidence Communication flow Testing Story + Product Story?Self-herding Awareness Ask yourself control (why) questions
  • 18. Wants vs Needs
  • 19. Wants vs Needs Sur vey ExpectationsExpertitis Quality gates
  • 20. Getting closer to needsTesting Transparency What’s involved Framing Root causes vs Symptoms Feynman’s “Why” Conway Heuristic
  • 21. Summing up
  • 22. Traps to congruent communicationSelf-herding Silent evidence Context oblivious Quality gates
  • 23. Getting to congruent communicationContext-free questions Context-specific questionsContext-specific reporting Reporting the whole context
  • 24. Congruent -> Satisfaction? Test brand building Making silent evidence visible Context-specific Trap awareness Trap evangelist
  • 25. Reading & Study ReferencesFICL: Russo & Schoemaker Taylorism in Testing Systems Thinking: Weinberg, Silent Evidence in Testing Larman Self-Herding: Ariely Linear TrapsSilent Evidence: Taleb Brand buildingCognitive Ease: Kahneman FramingContext-free questions: Gause & Weinberg Framing: Weinberg, Tversky & Why questions: Youtube - Feynman Kahneman, Russo & Schoemaker (magnets)

  • 28. Conway HeuristicTo communicate well about testing one must beable to misunderstand the communication(report, result, interpretation, explanation) in asmany ways as the other participants in thecommunication process.
