THREE stories.
A story about the status of the PRODUCT…
…about how it failed, and how it might fail...
…in ways that matter to your various clients.
A story about HOW YOU TESTED it…
…how you configured, operated and observed it…
…about what you haven’t tested, yet…
…and won’t test, at all…
A story about how GOOD that testing was…
…what the risks and costs of testing are…
…what made testing harder or slower…
…how testable (or not) the product is…
…what you need and what you recommend.

Anders Dinsen
"Testing In The Black Swan
Domain"
Black Swan Idea/philosophy:
The term black swan derives
from a Latin expression - In

lands, very much like a black

coined, the black swan was
presumed not to exist.

lot about computers. Most
software is made for people...

12. Conference Day 1 - May 8, 2012
Pass/Fail addiction
You feel good when starting a test with “Verify that…” and
ending with Pass or Fail
Pass/Fail rehab:
Look at some more places than what is stated in the Expected
Results field
Write the occasional test idea using the word "investigate"
You can ask richer questions than: Is this correct or not?

13. Conference Day 1 - May 8, 2012
Coverage obsession
A coverage model is useful to get ideas
Not useful as a metric of completion
A model can help you find important things, but a
percentage number might not include things that are
important
Information about the system is more important than
information about the model of the system (Emilsson)
