Mal eine Frage in die Gemeinschaft.
Vor längerer Zeit hatte ich Mal eine Anleitung wie man in ein #Debian stable einbaut das manche (nicht alles) Pakete aus dem #Testing oder #unstable installiert werden. Mit allen Risiken ich weiß.
Leider finde ich die nicht mehr.
Hat hier jemand einen Tipp 🤔
Andy is a huge proponent of test-driven development and explains why – including types of code testing including unit tests and integration tests, when you actually need to run tests, how long they should take, and more.
Why should you unit test? What should you unit test? And how much?
Today's blog post answers these questions and provides some helpful guidelines.
The post is actually a lightly edited extract of a book on unit testing that I started about 10 years ago but never finished. Still, it has aged reasonably well.
The other day my kid asks me to present math problems about area. Early middle school: simple multiplications and divisions. He got taught a formula for areas of trapezoids: A = 1/2h * (b1 + b2).
I decided to show him how to #unittest his #math solution, by giving him a different approach: A = a + 2b, where a = area of the square, and b = area of each triangle on the sides of that square.
He threw a fit and refused to accept my approach, because it wasn’t the same as he had learned.
Educators should avoid making belief that the approach they teach is the only possible one.
You cannot verify your approach by repeating it. That only tests whether it leads to the same outcome, but doesn’t verify. Instead, you need to find a different way to get to the same conclusion, and then compare.
