Famous last words: "Works for me!" Sometimes, even though code works for you, when you push it to the remote repository or install it on the production site, suddenly you're faced with pesky errors that escaped the testing process. The later bugs are found during development, the more expensive a project becomes in terms of time, frustration, and money. One way to improve your code quality is to use automated testing with Git hooks. In this session, Milton Bryant will walk you through some practical applications of automated testing using Git hooks. He'll demonstrate how to get Git hooks working with existing PHPUnit tests, to allow you to test your code as you commit it. Presented at the Joomla World Conference 2014 in Cancun, Mexico - November 7, 2014
