Florian, you understand stuff most people are not even aware of, very insightful. You are 100% right, yes, you should do it “TDDish way”.
However, even the current small scope made the article huge. And if I added “TDDish way”, it would double the article size. Eg, I had no physical strength to make something that big ) But I want to write on this topic in the future.
Thank you for rating my article high, I’m very grateful.
