Wayfair is one of the world's largest online destinations for the home. Our storefront is a very large PHP application -- 3.5M LoC interacting with a wide array of extensions -- that serves 2M daily visitors. So we were delighted when our upgrade to PHP7 went without a hitch. It worked so well because of a test plan that covered a wide range of strategies and tools. This case study will combine a walkthrough of this project with a practical tour of PHP testing tools, from PHPUnit to GDB.

Engineers are most familiar with unit tests and browser tests, but there's a much wider range of tools available for validating software. I'll cover the pros, cons, and applications of a dozen tools that work well with PHP applications. They'll be presented in context of a real application so people can get a good sense of where they should invest.

Thanks for sharing the processes. My only comment would be to reduce the amount of text on the slides to promote readability.

Good information. Agree with the comment above, some of the slides were hard to read.
