I'm happy to announce the arrival of my new book! :) It is called "Bad Tests, Good Tests" and is all about writing high-quality tests.

A simple code kata - "Pager" - which could be used by those who try to learn programming, and especially for TDD beginners.

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

A short story about refactoring of a simple utility method - from boolean parameters to the fluent interface. All in the name of making the API perfect. :)

I attended Global Day Code Retreat, Kraków, 2011. It was a very nice event. Below you will find some notes about it.

Is it good for developer to work with legacy code? Is it possible to develop new skills by doing this? Or maybe this is a dead-end that you should avoid? Let us find out.

Slides from GeeCON 2011 "Who watches the watchmen? - on quality of tests" are available. Enjoy ! :)

Few notes on two approaches to testing. Some people seem to be more interested in verification, others aim for better design.

Automation is the key to successful testing. This post explains why other ways of software verification are a waste of time.

Shortly speaking Javarsovia 2010 was great! I enjoyed it very much.

I want to thank very much to all people involved in the organization of this event. Great job! Everything worked fine and I was really impressed by the number of people that came to Javarsovia 2010.
