As you write your PHP code, you'll need to verify that everything is working as expected and that the code follows all style and formatting requirements. In this list from the SitePoint PHP blog they give you a list of eight tools you can use to ensure all of these criteria are met.

For shipping quality code, we must have testing in mind while coding (if not doing TDD). However, with the wide range of PHP testing tools out there, it’s hard to make a choice! Exploring PHP is a fun adventure (premium course on that here!) but it’s hard to assemble a toolbelt that’s not too heavy to wear to work!

This popular article will highlight the most popular testing tools and has been updated to reflect the state of QA tools in 2017.

Included in their list are tools like:

• PHPUnit
• Cucumber
• Selenium
• Kahlan
• php_testability

The post ends with a brief look at continuous integration and how they can help execute these tools automatically when code changes or before production builds are deployed, taking most of the burden off of developers to remember.

In a new post to his blog Lukas Smith looks at a recently introduced service, Travis CI that helps make continuous integration simple (and without having to set up the software yourself). He talks about his experiences in getting his trial project up and working with their system.

Continuous integration is one of these topics that had a slow start, but in recent years has really taken off. The slow start is likely to be attributed to the fact that it was perceived as hard to setup and maintain. But solutions around Jenkins and Sismo are making it easier and easier. But thanks to the new Travis CI service, its now essentially so easy that there is no excuse not to use CI for PHP projects, at least if you are hosting your OSS code on github.com. What makes this service so crazy cool is that you can run your tests against multiple PHP versions, multiples databases (heck even RabbitMQ) and against multiple versions of various libraries.

Thanks to the "first class" PHP support they offer, setting up a PHP project is as simple as creating a ".travis.yml" file in your github-based project (including PHP versions to test against, dependency management and "before script" tasks to execute). If you're looking for a CI platform without a lot of the hassle involved in the usual setup, you'd do well to check out Travis CI.
