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 Can exploratory testing replace executing manual functional tests?
+1 for Chuck's suggestion, which I love. I am a HUGE proponent of running experiments and capturing data. Doing so helps people learn a lot. In the absence of actual data, opinions prevail. The opinions that prevail often belong to those with the loudest voices and/or are HIPPO's (the Highest Paid Person's Opinion). Experiment. A Google search for W. Edwards Deming and PDSA would pull up some interesting articles and blog posts on this topic.

comment What are the benefits of Block Testing?
+1 for a wonderfully clear explanation and an additional +1 if I could vote it up again for these great sentences that should be carved in stone: "In the end, the math doesn't really matter. The reason to measure coverage isn't to produce a number - it's to help you discover what areas of the code are not covered by your testing so you can determine if more testing is needed. In other words, coverage testing is a method of discovering new tests."

comment Is it worth investing much time into iteration testing?
Dustin, You wrote your own software to create 2-way and 3-way coverage?! Cool! You're a man after my own heart. It's a shame so few testers know about these powerful test design methods. Please check out our Hexawise test case design tool and let me know your feedback. My experience confirms your assertion that moving from 2-way (pairwise) to 3-way tests has a much lower ROI than the 2-way tests because you'll often quadruple the # of tests executed to get to 3-way coverage with a much lower number of new defects found per test as compared to the bugs per test ratio from the 2-way tests.

comment Alternatives to Session Tester for recording exploratory test session results
+1 Rapid Reporter is a great tool and Shmuel Gershon (who developed it) is excellent at the tricky balancing act of incorporating input from users without having that lead to a tool plagued by "feature bloat." The result is that Rapid Reporter is a very nice tool that is extremely easy to use that has the vast majority of the features most users are likely to want. In addition, it doesn't take up much room on your screen when you're 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?"
