What is better than Test-Driven Development? Even more test driven development – this time with deeper tests. Unit tests are useful, but a few examples don’t prove our Ruby code correct. Can we approach mathematical proof without ballooning the lines of test code we maintain?
Since the early days of eXtreme Programming, tests have been touted as “executable documentation”. In practice, however, many tests fail to live up to that ideal and worse become a time sink when trying to decipher test failures. Using examples and focusing specifically on unit or developer tests, this talk …
Back in 2001 or so, there were some within the nascent Agile community who believed that direct collaboration between programmers and customers (or their proxies) would eventually obviate the need for professional testers. The context-driven testing community knew how unlikely that was. We are, after all, a community of critical …
A software tester and a software developer discuss their experiences working at a medical device company to improve a heart monitor’s software. They share some of their experiences of how they worked together not only to find bugs, but were involved discussions on design, deciphered the complex architecture of the …
Model-based testers design abstract tests in terms of models such as paths in graphs. Then the abstract tests need to be converted to concrete tests, which are defined in terms of implementation. The transformation from abstract tests to concrete tests have to be automated.
A/B testing is a great technique to experiment with changes to your product. At Etsy we make extensive use of them to test out ideas; we’ve got 30+ running right now. Although the concept is simple, the execution is a bit tricker then you’d think. This covers the common, and …
