Testing Cost

Writing Test Cases Manually Is Faster Than Modeling… Huh?

Over the years I have been wondering why folks involved in testing are not more eager to adopt practices that we have shown numerous times to be superior to current practices. Let’s face it, making sure that all the interesting scenarios and corner cases have properly, effectively, and efficiently been tested is not an easy task. In fact, the ...

Why System Modeling is Often Perceived More Difficult than Test Modeling?

Creating a system model – a model that directly describes the intended system behavior – is “easier” than creating tester models – models that describe the testing strategies themselves. This position has been demonstrated both within practical and theoretical frameworks. This correlates well with day-to-day observations of test managers: ...

End-to-End and Interoperability Testing with MBT

I recently had an opportunity to present in ETSI’s UCAAT conference a way to use component-enabled MBT to overcome some of the shortcomings with current interoperability and end-to-end testing approaches. Because this raised quite a lot of interest in the conference, I wanted to write a short blog post about the subject. (more…)
