Interview With David Walsh

By Rey Bango

Have you ever meet a brash punk kid that annoys you to no end but he’s so damn talented that you can’t help but want to work with him? That’s how I felt when I first met David Walsh several years ago. Since then, I’ve seen him mature into a respected and often quoted software developer and most recently, a new dad. He hasn’t lost his snark and feistiness and he continues to hone his skills daily, often sharing his best tips on his awesome namesake blog.

From Procedural to Object Oriented PHP

By Patkos Csaba

This tutorial was inspired by a speech given by Robert C. Martin that I watched a year or so ago. The main subject of his talk is about the possibility of picking The Last Programming Language. He addresses topics such as why should such a language exist? And what it should look like? However, if you read between the lines, there was another interesting idea that caught my attention: the limitations that each programming paradigm imposes upon on us programmers. So before we get into how we could go about converting a procedural based PHP app into an object oriented one, I want to cover a little bit of theory beforehand.

Whoops! PHP Errors for Cool Kids

The library’s main features are:

Parallel Testing for PHPUnit with ParaTest

By Brian Scaturro

PHPUnit has hinted at parallelism since 2007, but, in the meantime, our tests continue to run slowly. Time is money, right? ParaTest is a tool that sits on top of PHPUnit and allows you to run tests in parallel without the use of extensions. This is an ideal candidate for functional (i.e Selenium) tests and other long-running processes.

ParaTest at your Service

ParaTest is a robust command line tool for running PHPUnit tests in parallel. Inspired by the fine folks at Sauce Labs, it was originally developed to be a more complete solution for improving the speed of functional tests.

Since its inception – and thanks to some brilliant contributors (including Giorgio Sironi, the maintainer of the PHPUnit Selenium extension) – ParaTest has become a valuable tool for speeding up functional tests, as well as integration tests involving databases, web services, and file systems.

ParaTest also has the honor of being bundled with Sauce Labs’ testing framework Sausage, and has been used in nearly 7000 projects, at the time of this writing.
