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 How to make sure your test data are correct?
Bj, Well said. I especially like the high "insight per word ratio" of these sentences: "Of course a model is an abstraction of reality, and so your generated data is only as good as your model, your equivalent sets, and how you parameterize the use of those sets in your generator. Data generation can become quite complex and could also include weighting specific values, sequencing, etc."

comment How can I report coverage on an n-dimensional test matrix?
I've added some new screen shots of the green and red "Matrix Reports" because some testers like how they provide a clear summary coverage achieved as well as specific gaps in coverage that exist. (These views were not previously available).

comment What online games (ideally with a bunch of glitches) would make for a good software testing training exercise?
devonps, I or one of my colleagues are in the classroom together with participants when we run these test design training sessions. If the testers struggle, we would encourage them to try out different approaches and ideas. Rarely do we need to do more than that. If we need to, we can gently guide participants in a direction that is likely to be fruitful.

comment What does “all triples” test suite means?
Chris, You're generally on the right track, but there are a couple subtle but significant inaccuracies in your answer: (1) "every value of every variable is included in at least three tests." - Not so. Rather, 3-way coverage means that every possible triplet of values appears in at least one test. (2) "The variables should be independent of one another." While I've seen this claim in multiple sources, it just isn't true in practice. In fact, combinatorial testing is often especially useful where variables are dependent (but extra care needs to be taken in modeling the System Under Test).

comment Statistical Testing Application on Screens and Nested Logic
I'm not really sure what the question means. As Kate suggests, more detail would be helpful. Could you provide a sample test scenario or two by way of example? Do you envision each test scenario each including all 3 screens being opened in different orders?
