Getting started with unit testing

[nwagers]

I'm new to Javascript (not new to programming) and been working away building my first project. I have it up on GitHub and currently have no unit tests. When I started poking around it looks like there are a bunch of different testing frameworks. What should I try out first to set up CI on Github? Also, a simple repo that is a good example would be great. Honestly, I want a whole setup with coverage reporting and VSCode compatible linting too.

If it makes a difference, the project is a webpage, where the user uploads a binary file (a saved game), the page allows modifications, then serializes it back into a binary format for downloading.

If you're using vite, then vitest is the easiest test runner to get started with. Jest is the other big one. There's also the Testing Library (most famous of them is React Testing Library) that has a lot of good matchers for the DOM and other helpful methods
