This is a list of talks given by Qafoo experts at international conferences and other events.
Testing Oxid ShopsGet a Qafoo expert to support your team on-site with getting into BDD with Behat: contact us right now.
Frustrated by the limits of Unit-Testing in complex and fast changing environments? There are alternative ways of software verification, which work better in modern agile environments for complex applications like online shops. This talk will introduce you to several concepts, like integration tests, BDD and frontend testing, which can improve customer communication and stability of your product.
Behavior Driven Development with BehatUnit tests give you a good base to ensure your classes are working technically correct. Integration tests show that they play well with each other. But who takes care that all your code actually does what your business owner wants it to do? This session gives you an introduction into Behavior Driven Development on basis of Behat to help you achieve automated testing of specifications.
Designing Beautiful APIsDesigning interfaces is an every days job for every programmer. But it's not only a job, it's an art. Be it a brand new application OO design, a shiny new module, in infrastructure library or just a single new class: All of them need a flexible, usable and extensible API. This talk gives a round up on essential rules that you need to obey in order to reach this goal.
Continuous Performance TestingDuring the last years the topic of software quality assurance got more attention in the PHP scene. One important part of this are software metrics, which provide you with the necessary tools to overview and measure a project to detect possible failures early. This session will explain you metrics, so that you can use them in your daily work.
Building Testable PHP ApplicationsAutomated tests give you the secure basis to constantly evolve, improve and refactor your PHP app. But, what tests are suitable for which parts of your app? How to write code to be easily testable? And how to integrate such tests into your build process? This talk answers these questions in an overview of state of the art testing of PHP apps.

Testable CodeWriting testable code is a challenge that touches various aspects of software design and development. In this workshop, you will gain detailed insights on theoretical and practical aspects of writing testable code. See what makes code testable, how to make code testable and how to identify code that should be made testable. You can bring your own code to this session, to get it analyzed on stage, if you want.
Make Your Project SOLID!The 5 SOLID principles incarnate the essence of good object oriented design and programming. Sadly, only few people know about them and even fewer obey to them in their daily work. This session will not only explain the principles without lots of theory, but also show you how to realize them in your everyday work, using practical examples from real world projects.
Black Magic with Regular ExpressionsRegular Expressions in PHP are an amazing tool, which can be used to validate input or extract information. Furthermore they are used inside of parsers to provide lexing capabilities.
As the second part of our RegExp webinars this session will detail all the fun stuff possible with PCRE: Named Subpattern, Greediness, Assertions, Unicode, Defines and more.
If you have some introductory knowledge about Regular Expressions, but are keen to learn what else is possible, join us in this Webinar to learn more sophisticated usages.

Dependency Management with JavaScriptJavaScript Projects are getting more and more complex every day. JavaScript has evolved from a language to create simple augementations to static content, to a language which is utilized to create whole application eco-systems. In order to keep up with this trend code needs to be structured and dependencies need to be managed. This sessions helps you to understand how to accomplish this task.
Die perfekte Build PipelineWer kennt nicht das Problem? Das Projekt verwendet diverse Tools für Entwicklung, QA, Deployment. Natürlich müssen sie auch auf allen Systemen vorhanden sein, lokal, CI-Server usw. Gleichzeitig werden managementkompatible Auswertungen benötigt, die die Aufwände rechtfertigen. In dieser Session zeigen wir, wie man eine solche Build-Pipeline für PHP- und JS-Projekte mit geringem Aufwand realisiert.
jQuery-Mobile vs. Sencha TouchThe mobile web -- getting more important every day -- provides developers with new challenges. To ease the pain of developing mobile JavaScript applications different frameworks evolved. Sencha Touch and jQuery-Mobile are two of those. But, how do they differ? Which one is the best for your task ahead? This session gives an introduction into both frameworks and spots the key differences. Let the battle begin!
Closure Design PatternsJavaScript is a very powerful language. Eventhough it supports object-oriented design and development paradigms utilizing its prototypial concepts, it has further astonishing capabilities in other areas of expertise. One of those are closures and all of the different possibilities provided due to this language feature. This sessions does not only provide you with a short introduction to closures themselves, but presents you with a certain amount of design patterns which just perfectly fit this nifty language feature.

Domain-Specific LanguagesBe it just an advanced configuration format or a more complex language to adapt your application to changing needs rapidly: Domain-Specific Languages (DSLs) occur more often than you think and can even more often be of help. This session gives you an introduction into DSLs, where and how to use them to ease development, react rapidly to changes and improve communication.
Immer am Optimum, Continuous PerformanceWie überprüfen Sie, ob Ihre Webapplikation die gewünschten Leistungsanforderungen selbst bei komplexen Nutzerinteraktionen erfüllt? Es gibt eine Welt jenseits Apache Bench und Siege: JMeter kann Nutzerinteraktionen simulieren, komplexe Cluster-Setups profilen und einfach in ein bestehendes Continuous Integration Setup integriert werden. Wir zeigen, wie JMeter verwendet werden kann um die Performance einer Anwendung kontinuierlich zu überwachen.
Domain Specific LanguagesDomain Specific Languages (DSLs) can enhance many projects, as just a powerful configuration format, a way to conveniently customize your app for different use cases or to ease communication with non-developers in your team. But, what's the buzz all about? When do you want or need a DSL? How to design one and realize it? This talk gives you an introduction into DSLs on basis of hands-on examples in PHP.
Understanding Regular ExpressionsRegular expressions seem to be some kind of dark magic for many developers. Although easy to understand, they consist of strange characters like brackets, dots, asterisks and questions marks. However, as soon as you have understood what is going on behind the curtain, you do not want to miss regular expressions in many areas.
This session does not only allow you to lift the veil and read as well as write the seemingly magic regular expressions, but also demonstrates how and where you can employ them by working with examples in step with actual practice.
