There are plenty of books that show the aspiring PHP programmer how to use testing tools. But how do you actually build your application in such a way that using the testing tools is easy instead of a constant struggle?

The guide is aimed at helping intermediate level programmers build applications that should be easier to test and hopefully to maintain. My goal is to show you that it really isn't a lot of extra work to create an application that consists of small modules of code that know how to speak to each other in order to solve larger problems. You'll learn why automated testing can be an essential tool and how your choice of components for your application makes all the difference in your pursuit of releasing bug-free code into production.

Let my programming experiences help you become a better programmer and let you fix problems faster and add new features to your application with confidence.

The guide is broken down into the following sections:

1. Testing Is Good, Testable Applications Are Better
2. Building Testable Applications Is Hard
3. Environmental Consistency
4. Static Code Analysis
5. Decoupling Your Objects Using Dependency Injection
6. Like An Onion, Your Application Has Layers
7. Shells and Sandboxes
8. Rebuilding Your Programming and Deployment Environments
9. Continuous Integration Landscape for PHP Developers
10. Where Are The Tests?
11. Advice From A Grumpy Programmer
