Jenkins provides a lot of useful plugins but you do not need all of them. Here is the list of plugins I use to customize the view of Jenkins.

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. :)

Long time ago I got attracted to mutation testing (http://en.wikipedia.org/wiki/Mutation_testing). Alas, at that time all the Java mutation testing tools were useless: abandoned and forgotten long time ago.

Want to have always the latest documentation and database schema available? Then build it on your CI!

Recently I spent some time working with legacy code. The usual stuff - fixing bugs, introducing requested changes. In this blog post I share some comments on working with such code.

Recently, when working with maven-release-plugin (used in some old, long forgotten codebase) we encountered few issues. This post explains two of them.

That is pretty cool that your CI polls SCM every minute to build and tests your code instantly. However, you still need a nightly build. Read why.

One day I started to experiment with visualization of test dependencies. I thought that maybe Graphviz can help to provide some nice diagrams that would help me see instantly what went wrong, and why some tests are skipped. In this post I present my achievements so far.

The source code is available at github. Enjoy !
This post shows how to generate nice database diagrams using SchemaSpy, HSQLDB and Groovy. And, what is crucial, to do so in programmatic way, that is without clicking any GUI.

Oldest developers can't recall the times when TestNG introduced timeout constraints for tests methods (invocationTimeOut parameter of @Test annotation). The current beta of TestNG allows to set timeouts also for configuration methods.
