While unit, integration and system tests - especially the methodology of Test Driven Development (TDD) - are great ways to push the technical correctness of an application forward, they miss out one important aspect: the customer. None of these methods verify that developers actually implement what the customer desires. Behavior Driven Development (BDD) can help to bridge this gap.

With our talks, we shared some of the Qafoo knowledge on Building Testable PHP Applications, Continuous Performance Testing, Understand and use software metrics and Designing Beautiful APIs. Find our slides for download here.

Pretty much the same works for learning to play a musical instrument. The idea of Code Katas applies this simple, but for many aspects effective, method of exercise to the world of programming.

Qafoo experts are part of this outstanding experience for several years and will be again from February 25th to March 1st 2013. This year, Kore and Toby will be on-site to share a bit of Qafoo experience with you on the following topics.

As a 3rd "usual" thing, I did a tutorial and a talk there: On how to write Testable Code and to Make Your Project SOLID by applying these 5 fundamental principles of object oriented design to your code.

I am covering some slightly advanced topics, like subpattern options, unicode and backtracking aka. greediness and performance.

This often focusses on dicussing metrics, browsing the associated code and discussing solutions for the issues found. We started using a bunch of shell scripts for that, like everyone else, but at some point we came up with a webinterface to do this in a more comfortable way. Now we want to share this tool with you.

This is fine as long as it works for you, but might lead to problems in the long run. In this article I discuss the semantical differences between abstract classes and interfaces. I also outline why following the semantics of those language constructs can lead to better code.

We just released a tool, which we developed internally to be able to debug complex HTTP based SOA stacks (REST). It offers the same listening capabilities like Wireshark, but displays the HTTP requests in a far more readable way and makes it easy to reproduce single requests. Read more…
