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 Where can I find some amusing cartoons about software testing?
+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).
