On NetTuts.com today they've made an announcement about a new PHP testing course they're making available for free. The course is an introduction to testing your PHP applications and is taught by Andrew Perkins.
In this course, Andrew Perkins will teach you the very basics of testing in the PHP language. Learn what is needed to test PHP applications and why testing is important. Explore the differences between regular testing, test-driven development (TDD) and behavior-driven development (BDD). Along the way, take a look at the various frameworks that are available, to make sure your PHP websites run just as you expected. And lastly, compare and contrast the different types of tests that you can run such as unit, functional, and acceptance tests.
The training course covers a lot of the basics behind testing and several of the tools you can use along the way including PHPUnit, Codeception and Behat. It's a pretty quick overview, so don't expect too much in-depth coding and testing examples. The course with all videos included comes in at just a bit over an hour of content. You can find out more and sign up to have access to the training here.
