At LexBlog, my team is responsible for keeping a lot of sites up and running. We help manage the reputation of lawyers and law firms, where each pixel matters. As a result, our product team performs a host of functional tests before launching updates, and we lean on test driven development practices to catch things that functional tests cannot.
An unfortunate blind spot is that humans aren’t machines. We’re prone to miss simple things, and after staring at a screen for hours on end, our brains and eyes get tired. To help catch things that we may gloss over, we use an internal application built using Node.js, React, and Selenium that integrates with the WordPress REST API and an external service, Applitools.
