This article covers the unique challenge in defining testing scope and expected results when testing systems with non-deterministic outputs whose accuracy improves over repeated iterations of the same inputs. A thorough understanding of the algorithms under test and excellent communication between development and testing are essential in test scenario definition and predicting anticipated outcomes. Defining tests and expected behaviors prior to the start of testing is especially crucial in these types of conditions.

Real-World Reasons for Investing in CM: At CM Crossroads, most discussion is about software CM. Many SCM practitioners are looking for help on-line, and SCM tool vendors keep adding more and more features to their products, pushing the envelope of CM. But no matter how far the envelope is pushed, software configuration management will remain a subspecialty of "plain old" configuration management.

Much of our behavior is automatic. We breathe without thinking about it, and we blink without much conscious effort. We do lots of other things without an iota of thought. In this column, Naomi Karten explains how jumping to conclusions is yet another thing we do without thinking about it—for better or worse.

Within the test scene there is a vivid discussion about the necessity and use of a certification model for the test experts. The population of testers can be roughly divided into two groups: Firstly, a group that states that it will not do a better job when certified, because the current certifications like ISTQB and ISEB focus on methods and terminology, but fail to look at the practical testing skills of the tester [Bolton, 2008]. Secondly, a group who is pro certification and regards the testing industry as a young yet not fully grown profession that lacks certification models that other professions have been using for ages [Windsor 2007]. Meanwhile, voices are heard that the test profession is accepted in the IT industry and that it has actually grown into a mature profession. The website of the last EuroSTAR conference stated that a mature profession has clearly-defined standards, codes of conduct, and a number of levels of professional competence. Having all those, we might conclude that the testing profession has indeed earned its place among the IT-professions.
