chaijs VS ava

I'm using AVA for testing and that detects the module declaration and works just fine running ESM tests.

We recently switch to Jest framework when writing Unit and Integration tests in our React and Node applications. We used Mocha many years ago and AVA for a few years.

The other day I needed to test a React hook with Ava, which lead me to try to use React Testing Library, and it took me a few minutes to figure out the best way to do so because the documentation to do so was spread over several pages.

I really enjoy Ava [1] or anything assert-tape-like [2]. "uvu" [3] is getting a lot of love lately, but it's very feature limited and much of it's touted advantages are at the detriment to feature set.

Jest is great for front-end (or full stack integration) testing, but I feel it's specialized for that use-case and doesn't always play nice with backend/middle-tier testing needs.

AVA

For unit tests AVA is fast and simple : https://github.com/avajs/ava

But this commit broken the unit tests. I use Ava (the only test runner that allows for async tests, so I can write unit tests in my own language) and snapshots for testing the list structure in few unit tests, and somehow the snapshots differ before and after adding iterator to Lists. I still need to investigate why and try to create simple reproduction for this issue on GitHub avajs/ava#2811.
