Code coverage does not make much sense for Behat tests, except for if you use them on legacy code as wide-coverage test cases, before starting to refactor. This blog post shows you how to generate code coverage information for your Behat test scenarios.

The use of Mock and Stub Objects is an important skill to learn when using Test Driven Development (TDD). Mock objects allow you to replace dependencies of an object with lookalikes, much like crash test dummies are used during automobile safety tests so humans aren't harmed.

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.

In almost any kind of sports you hone your skills by repeating a small piece of practice over and over again. Pretty much the same works for learning to play a musical instrument. The idea of Code Katas applies this simple but effective method of exercise to the world of programming.

We, at Qafoo, do Code Reviews quite often together with our customers. 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.

Features of object oriented languages are often use from a purely technical perspective, without respect to their actual semantics. 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.

From time to time I trip over APIs, which do not allow me to control the object lifecycle of the used objects myself. Let me discuss why this is a bad thing…

Already some time ago I published a tool on Github which allows you to generate (or learn) XML schemas from XML data. You provide the tool with a set of XML files and you get a nice, human readable, XML schema (XSD, DTD, …) from that. Read more for the details.

This is a provoking title, but, in my honest opinion, a very valid rule of thumb. During the last years of teaching other developers, developing PHP libraries and applications and doing quality assurance on other peoples software I came to this rather abrasive conclusion - let me tell you why…
