Editor's Notes

  • 10 minute version
  • Ru’s story: regression means exploring, never understood that it means it is worse than it was. Retest / regression.
  • 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
