XP2015: Breaking your illusions with Exploratory Testing

Editor's Notes

  1. 10 minute version
  2. Ru’s story: regression means exploring, never understood that it means it is worse than it was. Retest / regression.
  3. Illusion stories: “I tested it, it works” “reporting engine” “no time for refactoring” / “releasing as scheduled over done” “Need document grouping feature over others” --- Ray Arell (Intel) giving apple example: showing you’re living with an illlusion. Tester mentality!! ---- Point of this slide: BUGS not defects: anything this might bug a user, there’s many types of illusions we have Finding really expensive bugs: missing value, wrong features Illusion: releasing as scheduled (sprint) vs. releasing when done (kanban) EMPIRICAL evidence trumps speculation. Every Single Time. – testobsessed
