Warning - 3/4 finished thought.

In the event of an unknown or unexpected system behavior in the software world - the test plan documents mean nothing.

When we develop our testing strategy we do two things - outline what we WILL  test AND what we are NOT going to test. The latter is always one of the hardest to figure out, explain and do effectively.  A close relationship with development is required. Trust from both sides is crucial. Expert knowledge of the system and how changes affect it is required. 95% of the time this process works but other times it backfires. It is usually the unknowns that screw us.

For project X a lead tester wrote a test plan document to satisfy project stakeholders. The document brought up lots of good questions and discussion. The one section that got a fair amount of discussion was the “Not going to test” section. We explicitly stated that PERFFORMANCE would NOT be TESTED. We would eyeball the performance (web based UI connected to our 4 year old core server technology) and not provide a formal analysis of request/response times. Why take this approach? We had done load testing with a shipping release build 1 month prior. We got benchmarks, provided this info to development and discussed the risks. Everything looked good. There was no reason for any of us to suspect performance problems.  Everyone agreed “There should be no reason we would have performance problems”. All project stakeholders “signed off” on the test plan. 

What do you think the single biggest problem found while testing?

Michael Hunter, of Braidy Tester fame, posted a challenge on his blog. He showed a parking sign photo and asked how many different ways it could be interpreted. I decided to take 45 minutes during one of our weekly test team meetings and try it out. What the hell does this have to do with testing you might ask? Well - thanks for asking. Here is how it relates for me

• Idea generation - we always need to generate new ideas for testing
• Clarification - requirements are mostly ambiguous and this was practice at clarifying them.
• Sharing and discussion of ideas - “It could be interpreted this way” which lead to someone else saying “Yes and this way too” - Team work, supportive attitude with a focus on sharing.
• Time boxing so we don’t get carried away - Important in testing and just about anything else
• Coming up with alternate solutions/problem solving - It’s good to be seen as a problem solver instead of “Bearer of Bad News”

Needless to say we had a great time doing this activity. I time boxed the idea generation to 15 minutes and then had about 15 minutes of discussion.  We used index cards to write down our ideas. We went around the room and each person read an idea from their card. We ran into some duplicate ideas but that was ok - we weren’t focused on having every idea be unique. The puprose was to put on our “thinking caps”

Now it’s easy to take an idea and tear it to shreds.  To quote Edward De Bono in The Thinking Course “..critical destuction of one hypothesis has never produced a better one. It is creativity that produce the better hypothesis.” As a follow up challenge I asked the team to come with a sign that wasn’t ambigous. We explored some great ideas and had a great discussion. A few of the ideas and designs came out to be really clear and (mostly) unambiguous (I’ll have to get them and post it with this article.) The discussion was going so well that it actually went over time and into lunch.

Here are the results which were summarized by Aqiqul Hoda and Michael Hetmanczuk. The participants were Adam White, Alan Walker, Ali Khan, Aqiqul Hoda, Christy Gnanapragasam, Herb Bal, Joseph Kubik, Michael Hetmanczuk, Mortaza Abhari, Thomas Yook and Zhe Chen

16. Board number 2: hour parking
17. Is the #2 the sign ID or does it indicate 2 hours?
18. Can we park during other ours or only 7 AM - 6 PM
19. Where is the sign?
20. Does it mean I can park from 6 AM - 7 PM?
21. Hol?  What qualifies as a holiday?
22. Does this apply to bikes?
23. Except sun/holiday means on Sunday and holidays - no parking at all
24. On sunday/holiday you can park all day
25. On sunday/holiday the 2 hour limit is lifted, but parking is only
allowed from 7 AM to 6 PM.
26. Zone 4 permit means you can park all the time.

28. Except Zone 4 permit means you can’t park at all if you have a zone
4 permit.
29. Except Sun/Holiday: means only those with a zone 4 permit can park

I mentioned that I would post more about the acquisition of PlateSpin by Novell. I’ve been delayed in doing tihs because there isn’t that much to report. We are being told that it’s business as usual and that’s what it’s turning out to be. Novell hasn’t had a strong presence in the development area - although this isn’t true for other areas like sales and professional services (from what I can see). There hasn’t been any fall-out or mass exodus of employees. 

I’ve heard people talk about acquisitions like the exodus is the “norm” either because it’s a technology acquisition and the acquirer doesn’t keep the employees or because they are scared that will happen. There have been little rumors going around about this person or that person leaving but nothing can directly link to the acquisition.

Alan Page pointed out a page that he found to related to my previous bug. He found this using Live search instead of google. 

The good news -it worked in the sense that the stupid error messages are gone. Interestingly enough 3 feeds that worked previously now don’t work. And I discovered this neat duplicate error message bug.
