docs: recommended way to test a node plugin on GitHub CI?

TLDR

There seems to be lots of testing frameworks for vim scripts:

• https://github.com/cdelledonne/vim-utest
• https://github.com/dhruvasagar/vim-testify
• https://github.com/LucHermitte/vim-UT
• https://github.com/junegunn/vader.vim
• https://github.com/google/vroom
• https://github.com/kana/vim-vspec
• https://github.com/thinca/vim-themis
• ...

Should I use one of them and just call my node exported test function from vim script? If so, how do I get the test results output?

Should I use a technique similar to what node-client is doing instead, see https://github.com/neovim/node-client/tree/master/packages/integration-tests ? If so, how do I get the test results output?

Any pointers or help is appreciated.

This is how I currently test my neovim node plugin locally

I've got a neovim node plugin that exposes a test framework entry point. This function ends up calling into mocha in order to run all the tests.

I am able to run the tests nicely from a local environment after neovim starts by calling the test framework entry point from the neovim config. And I can read the output from the log file that is written thanks to the NVIM_NODE_LOG_FILE environment variable.

Start by reading the node-client packages/integration-tests example and the linked Cursorless entry points: packages/test-harness/src/index.ts, cursorless.nvim/lua/cursorless/init.lua, and the recorded test suite. Determine whether a Vim-based or node-client-based GitHub CI approach is recommended and how test results should be exposed; done means documenting a reproducible workflow and its output handling.
