Hey there 👋

Disclaimer, this guide was done for my latest involvement with a React app, thus the examples are based on React 17 and thus this article will not address async rendering, suspense, etc. Also, the docs linked are from the legacy documentation for React 17. Problem Statement React, despite being one of the most popular front-end libraries, doesn’t have primitives, nor in the framework, nor in the underlying language to ward off performance issues....

But why? As I layed down the various requirements for my game engine, a requirement that seemed of vital importance was the ability to tests shaders and other graphical features. I live and breathe by TDD but I cannot do integration tests with a driver such as Vulkan or OpenGL (or maybe I can just not willing to do down this rabbit hole). An alternative is to do visual regression testing....
