I wanted to share something I published today: http://drupalignite.com.
Basically it's a tool and a set of practices to setup a Drupal environment under a full Continuous Integration cycle using some well-known tools as drush, phing, composer and jenkins for the build phase, phpunit and behat for the testing and features and migrate for keeping everything (structure and data) in a code driven development shape.
I published the introduction, the following chapters will be published in the next months!
You can find the code on github: https://github.com/omissis/drupal-ignite
I hope you will find it interesting and helpful! :)
