Re: Nov 16 - Day 5: Reusable Code Tests & Concluding Remarks

@gongji: How to guess the combinations of features to test when you don't how a customer would use it is a good questions. In a printer, for example, we could print a page on letter paper at 600 DPI single-sided. And we could print on ledger paper at 300 DPI double-sided. And many other combinations of settings for the print job. I wrote a random tester which randomly set about 20 parameters and then tried to print page. We did find one obscure defect with that method. But was it enough? I came across this article, "Combinatorial Software Testing" in IEEE's Computer August 2009 magazine that addressed that very topic. I downloaded their ACTS software (http://csrc.nist.gov/groups/SNS/acts/) and played with it, but as is typical, real work interfered with research for a better way.
