Interviews on Software Testing
Blog: Curious Cat Management Improvement Blog
I haven’t added a new post here recently. One of the things that has been keeping me busy is putting together some interviews on software testing. Here are excerpts from 3 of the interviews:
Testing Smarter with Alan Page
Hexawise: During your 20 years at Microsoft you have been involved in hiring many software testers. What do you look for when choosing software testers? What suggestions do you have for those looking to advance in their in software testing career?
Alan: The biggest thing I look for in testers is a passion and ability to learn. I’ve interviewed hundreds of testers, including many who came from top universities with advanced degrees who just weren’t excited about learning. For them, maybe learning was a means to an end, but not something they were passionate about.
The testers who really impress me are those who love to learn – not just about testing, but about many different things. Critical thinking and problem solving are also quite important.
As far as suggestions go, keep building your tool box. As long as you’re willing to try new things, you’ll always be able to find challenging, fun work. As soon as you think you know it all, you will be stuck in your career.

Hexawise: It seems to me that testing games would have significant challenges not found in testing fairly straightforward business applications. Could you share some strategies for coping with those challenges?Alan: Combinatorial testing is actually pretty useful in game testing. For example, consider a role-playing game with six races, ten character classes, four different factions, plus a choice for gender. That’s 480 unique combinations to test! Fortunately, this has been proven to be an area where isolating pairs (or triples) of variations makes testing possible, while still finding critical bugs.
Beyond that, testing games requires a lot of human eyeballs and critical thinking to ensure gameplay makes sense, objects are in the right places, etc. I’ve never seen a case where automating gameplay, for example, has been successful. I have, however, seen some really innovative tools written by testers to help make game testing much easier, and much more effective.
Testing Smarter with Dorothy Graham
Hexawise: When looking to automate tests one thing people sometimes overlook is that given the new process it may well be wise to add more tests than existed before. If all test cases were manually completed that list of cases would naturally have been limited by the cost of repeatedly manually checking so many test cases in regression testing. If you automate the tests it may well be wise to expand the breadth of variations in order to catch bugs caused by the interaction of various parameter values. What are your thoughts on this idea?
Dot: Nice analogy – I like the term “grapefruit juice bugs”. Using some of the combinatorial techniques is a good way to cover more combinations in a reasonably rigorous way. Automation can help to run more tests (provided that expected results are available for them) and may be a good way to implement the combination tests, using pair-wise and/or orthogonal arrays.
