Counting Defects Defect counts are often considered as measurements of product quality. However, the most important defect count in that respect is by definition unknown; the number of undiscovered errors. Defect counts can be used as indicators of process quality. In doing so, one should avoid assuming simple causal relations. Defect counts can provide useful information but have to be presented with care. |

The Open Source Test Tool Paradigm Testing is often seen as an effort to determine the quality of the product at the end of a project, so it needs to be executed when development has finished instead of being a means to deal with risks at the earliest stage possible. Therefore, project budget, is in most cases spent on the processes that actually produce tangible products, at the expense of the testing budget. Whatever budget is left for testing will be spent on people rather than on test tools, especially since most of the mainstream tools are often perceived to be too expensive. A solution to this may be found in the use of open source test tools. With no license fees, the use of open source tools can provide a customer some of the benefits of test automation, without the costs. |

Are Templates Dangerous? When we mindlessly use templates to give easy answers, we're trying to play chess with a checkers mentality. That's David Gelperin's warning in this article. Templates related to context-sensitive issues require a lot of analysis. As he aptly suggests, "Perhaps every test doc template should come with a warning label: 'Not a Substitute for Thinking.'" |

Scalable Test Design Using Ultra-Understandable Decision Tables This technical paper describes a scalable strategy that integrates multiple techniques into a pragmatic test-design approach that honors budget and schedule constraints. The strategy is most appropriate for large sets of behavior rules and logical interpretations, where exhaustive testing is not feasible. Ultra-understandable decision tables and their supporting entity profiles are used to describe behavior, but the design strategy can be applied to any equivalent information model. The scalable design process comprises five steps. |
