Rubber Duck Not Only For Code Reviews

We all know that rubber duck is programmer's best friend (it was also proven that such duck should be yellow for maximum effect). Not surprisingly I have also a yellow toy on my desk. But it is not a duck. It is a little yellow human-like figure.


Refactoring Time-Related Test

This is a short story of a bad "refactor" of test code. In Poland we say, that "dobrymi chęciami piekło brukowano", which basically means, that trying to do something good can lead to really bad results. Well, I tried to do something good and I failed. Let us take a closer look.

Few days ago I learned a very simple, yet powerful trick which saved me some time. To make long story short, it happened on a test environment shared between few projects.


Finding Latest Versions of Dependencies With Maven

I use Jenkins + Maven + SVN in this example, but you can use this "tricks" also when using different technologies - Gradle, Git etc.


You Shall Not Test Methods

When discussing unit tests it often happen that I hear that "unit testing is about testing methods". I do not agree, and because this is something which surfaces here and there so I think the idea deserves a comment.


Failed Build? Never Again!

Oh, a failed test again! And not on your local machine but on the CI server! What to do, oh, what to do?!


Test Code Comments

Should you put comments in your tests code? Yes? No? Why?


This used to be my blog. I moved to long time ago.
