It was quicker to write these less-than-100 lines than trying to understand or at least make sense of all those projects.
I could also write at long about the benefits of providing a very simple working example in every open source project page, so that potential users can quickly decide whether the project might work for them or not, but I thought it would be better to lead by example. So here it is. That's how you set up and run tests with munit.js. No prototyping, no enterprise-y robust best practices to follow, no long, tedious and boring set up, no Java servers to run, no clients to instantiate, no interpreters that don't quite work like your browser, nothing else but microtesting!
