    Defining and measuring metrics is easy. Adding yet another metric just to add yet another metric happens subconsciously. It’s easy to focus on the values of the metrics and make decisions or to measure success only by using them. And it’s easy to forget why are they being measured in the first place – if…

    Let’s face it, humans are bad in observing our own mistakes; we miswrite, misread, misunderstand, and miscommunicate often, without realizing it. As unit tests are often written by the same person who writes the code that is being tested, there is a chance that any mistakes in the code will be duplicated in the unit…

    Surely, everyone talks about the same unit in the context of unit testing, right? It may be that the world hasn’t completely agreed on it yet. There are likely two main religions about the unit. The first group, let’s name them as the ideologists, believe that the unit is always the absolutely smallest unit that…

    Agile is a synonym for nimble. Move along, nothing to see here. In the tech world agile is a term that raises feelings – both in good and in bad. Many of the tech guys have personal experiences and opinions related to the term. It could be, that even the author isn’t completely objective. It’s…

    Unit testing? You mean those automated fast tests, right? That is, hopefully, often the case. Unit testing is wired in our brain to mean automated tests and maybe you’re already thinking about your favorite unit test framework… But let’s zoom out a bit. Unit testing is testing pieces, the units, of software more or less…
