I am the founder and CEO of Hexawise. I'm interested in using Design of Experiments methods from applied statistics to improve the efficiency and effectiveness of software testing. The Hexawise test design tool improves coverage with the fewest possible number of tests. It uses pairwise, and other, more sophisticated methods of optimized combination testing.

comment When is it OK not to have dedicated testers/QA team?
Bruce, I disagree. Here is why: If the question were "I wonder when does the absence of dedicated quality assurance people does not lead to decreased quality of delivered software?"... I would agree with your point (and could accept the validity of your down vote). That was not the entire question however. The question begins: "It just came into my mind that there are no dedicated QAs in stackexchange team. Since they are indeed making an awesome product,..." Hence the references are, IMHO, extremely valid.

comment QTP vs Selenium
I strongly disagree that questions like this should be closed. I would MUCH rather see thoughtful analyses of the pro's and cons of tools (and other potentially decisive issues) aired and decide for myself which perspectives I find more compelling than have moderators conclude that participants are too immature to discuss the issues politely and rationally. If participants can't be trusted to discuss topics like this politely and rationally, the community has bigger issues to worry about.

comment How is Selenium different from other GUI automation tools?
Please don't close questions like these. Vote down vapid answers if you like but thoughtful answers to questions like these have the potential to be extremely useful to many people.

comment Where can I find some insightful cartoons and/or humorous content about software testing?
Also, see: stackoverflow.com/questions/528311/… as a precedent of a similar question that has been open on stackoverflow for several years. Like this one, it asks, "Is there cartoon-based content (related directly to the subject matter of the community) that is suitable to helping me advance my professional objectives?"

comment Where can I find some insightful cartoons and/or humorous content about software testing?
Thanks for your views. To clarify, I actually did edit it a great deal to establish the case for why it is a "real" question vs. one that could be construed as "mindless social fun". I wasn't aware of the vote to re-open options or flag for moderator attention options.

+1 for making it a community wiki. Great idea. A community wiki is a good way to go for a highly subjective question like this that (A) is more about trying to find multiple pretty good sources as opposed to finding "the one best answer" and (B) where good answers don't require a lot of explanation / detailed reasoning.

comment What types of testing are LEAST suited to using pairwise testing (and similar test design approaches)?
Rsf, Thanks for sharing your experiences. FYI, many pairwise test design tools have constraint handling features that mitigate the first problem (e.g., when some parameters are dependent upon others). Also, about the debugging challenge issue, while a valid point, (a) in my experience, I'd rather have the problem of "How do we debug this reproduce-able defect?" if the alternative would be "Why didn't we detect this defect during testing?", and (b) you can often quickly eliminate the vast majority of possible causes by looking at passed tests that contain similar combinations of test inputs.

comment Developers have code kata to practice skills. What test equivalents are there?
Thanks. I agree about Markus' speed. Seeing the huge number of Markus' blog posts uploaded during testing meetings is impressive.

revised How can I report coverage on an n-dimensional test matrix?
Added a link (now that I have enough reputation to do so) as compared to instructions to "search Google usin gthese 3 keywords."

comment How do you adapt agile testing techniques to a regulated industry?
Up voting. Nicely said Joel. I was going to say something similar, but you beat me to it. Tristaan, James Bach has spoken about achieving the paper trial objectives in a recent project he worked on (where he was helping to test medical equipment). They used a document-light, ET approach. A Google search might result in some interesting advice from James. (As if James gave any other kind of advice; always can always be counted on to keep things interesting).
