PHPUnit introduction

A short introduction into using PHPUnit for automated testing. 
The talk would cover the very minimum stuff to lower the barrier to get started with first tests. 
The presentation was and will already be held at different TYPO3 Camps in DACH Region. 
The Material is avaliable at https://github.com/DanielSiepmann/testing-talk. 
It would be possible to double the talktime. The second half would then be used to show some real live examples and to provide and overview of what comes after the first steps.
