The Future of Htmx
We do have pseudo-browsers written in pure js that you can theoretically use:
https://github.com/jsdom/jsdom
https://github.com/capricorn86/happy-dom
but they're about as reliable as you can expect: it's difficult to keep up the pace with the big three (or two) on standards compliance, and they usually don't even try.
So the only reliable solution is a headless Chromium, Firefox, and/or WebKit-based noname browser like the sibling says.

Testing your Solid.js code in vitest
You may have heard of vite, the slim fast dev server that scored an amazing as deserved 98% satisfaction on the state of js survey 2021. It's creators found unit testing too cumbersome and slow and decided to add their own perspective to the task. The result is vitest: it runs a vite server under the hood to transform the code to test as fast as possible, uses an enhanced flavor of chai to have jest-compatible assertions, integrates DOM mocking using jsdom or happy-dom and even the tiny-spy library that was just built as a separate library to allow for easy reuse is small and compatible with jest.
