Mistake-proofing a process both improves it (many poka-yoke solutions make the process easier to use) and prevents an error in case you still try something wrong. So I see the automated tests as a way to serve as a backstop, in case the process improvement you made to the software development process failed in some form…

When you have a situation that has many many many possible parameters and each time only a few possible choices (a few items you are trying to vary and test – in his example in the video, 2 choices) you wind up with a ridicules number of possible tests if you try to vary one variable at a time. But you can cover all the possibilities in just 30 tests if your coverage target is all possible pairs…

if a software developer changes the code, the automated tests are all run and if there is an error noted by the automated testing the code cannot be deployed to the production environment… Thus automated testing mistake proofs the process

I appreciate that you are helping spread the word about Combinatorial Testing software. I really wish this field was expanded on by the experts!

Thanks again

And also, please check out Hexawise, the new test design tool I have developed that uses these Design of Experiments principles to improve the efficiency and effectiveness of software testing. Proof of concept pilot projects we are currently conducting at multiple companies are showing the following results: (1) Reduction in time it takes to identify and document test cases of 30-40%, (2) Reduction in test execution times of approximately 25-35% (because fewer, more effective test cases are run), and (3) Reduction in cost to fix defects (because more defects are found sooner with the more effective test cases).

Free trials (and a free version) are available at: http://hexawise.com/users/new

Thank you.

John,

Thanks for getting the word out about the efficiency and quality benefits available through pairwise software testing and other forms of combinatorial software testing. It is surprising to me that the benefits are not more broadly known by testing community, given how fast, easy, and unambiguous it is to measure the benefits.

For any of your readers interested in finding out more about combinatorial testing, I would recommend a couple clear and concise articles posted at:
