React is a framework that has made headway within the JavaScript developer community. React has a powerful composition framework for designing components. React components are bits of reusable code you can wield in your web application. React components are not tightly coupled from the DOM, but how easy are they to uni...
There are a lot of PHPUnit posts on our site already (just check the tag), but it’s been a while since we’ve actually introduced people to it, and the tool has evolved significantly since then. This article aims to re-introduce the tool in a modern way, to a modern audience, in a modern PHP environment R...
I didn’t start out writing tests for my code. Like many before and since, my “testing” was to write code and refresh the page. “Does it look right?”, I’d ask myself. If I thought so, I’d move on. In fact, most of the jobs I’ve had have been with companies who don’t ...
Functional programming and testing. Maybe you’ve given them a try in isolation, but somehow you never made either a part of your regular practice. They may sound innocent by themselves, but together testing and functional programming can create an irresistible temptation, almost compelling you to write cleaner, t...
Last time, we developed some new features on top of Sylius’ core to indicate which products and their variants are low on stock and need replenishing. Now, we move on to seeing our changes in the UI, which means we will need to do a bit of StoryBDD testing. When browsing the list of products, we want to see a new...
The post on developing and testing new Sylius features was an introduction to the three types of tests that are used in Sylius – PHPUnit, Phpspec and Behat. In this part, we’ll extend some core classes to indicate color-coded inventory status. First, we’ll deal with the back end part. In a followup po...
When unit testing real-world code, there are many situations that make tests hard to write. How do you check if a function was called? How do you test an Ajax call? Or code using setTimeout? That’s when you use test doubles — replacement code that makes hard to test things easy to test. For many years, Sinon.js...
You’re probably already familiar with automated testing and its benefits. Having a set of tests for your application allows you to make changes to your code with confidence, knowing that the tests have your back should you break anything. It’s possible to take things a step further and write your tests befo...
Sylius is an e-commerce application / framework based on Symfony. It boasts 100% code coverage, which is impressive for a PHP application of that size. In this article, we are going to walk through the different kinds of tests available and try out some Test and Behavior Driven Development (TDD/BDD). See the Sylius in...
I’ll be honest, I don’t do much testing. When it’s really necessary and I’m working on big enterprise projects, I do, but in general, my personal projects are usually one-man-army proofs of concept, or fixes on already tested apps. [author_more] We’ve done our share of testing posts here a...
