Playing around with Git…

In order to try out new stuff and learn about new languages, tools and libraries, I created a little GitHub project. Right now I’ve uploaded some Coding Katas in different languages. Next week, I will try out python and upload some more stuff. Perhaps I should stop doing GameOfLife and FizzBuzz, it gets boring after the third or fourth language 😉

Btw, you can find the GitHub link also at the bottom right of every page!

My Heuristics for working with Mocks

From my experience, when introducing mocks to your testing, it is easy to get messy, hard to maintain code.

Keep in mind that these are not meant to be a path of virtue that I must slavishly follow. I often violate them and still feel that the code is good (enough).

A little self-accusation

I want to accuse someone for writing bad code. This person has written lots of crap for about 7-8 years. Little time went into refactoring and even less into automated tests. When I look at his code my first thought is “what the hell was this guy thinking?”. In many cases his approach to software design has proven to be harmful for me. For example, when forced to fix a bug that was introduced by my bugfix because I did not understand the code well enough. Continue reading “A little self-accusation”

Quick tips about practicing TDD

After using TDD at work for about 2.5 years, I finally feel that while I still need more practice I am no longer a novice. I am confident enough to post some advices that come from common pitfalls I’ve encountered when still at beginner level. While they might be obvious to TDD experts I often notice similar mistakes other beginners make. So I thought that I might write as well them down. Continue reading “Quick tips about practicing TDD”
