Add testing to `rmd.lua`

[she3o]

This is a work in progress. Don't pull yet. I will finish it after work.

I am wondering how to test UI in a live neovim environment. I'll look into how MunifTanjim/nui.nvim does it.

Hi @jalvesaq, can you check if the testing infrastructure works on your computer. make test.

[jalvesaq]

I will look at this now...

I have no idea why this happens. It works fine for me.

It seems like there is a dependency requirement that's satisfied on my machine. can you ensure that Busted is compatible with the Lua version that Neovim uses

luarocks install --lua-version 5.1 --local busted

and that the 5.1 interpreter is in $PATH

whereis lua5.1

tests/run fails after running

nvim --cmd 'set loadplugins' -l "$@"

This means whatever runs tests/run doesn't send $@ correctly. So there is something different with Busted

[she3o]

I just realized you ran tests/run instead of make test which may explain why this error happened.

make test runs eval $(luarocks path --lua-version 5.1 --bin) && busted --run r_tests which uses ./.busted to execute tests/run

[jalvesaq]

It works! tests fail because I didn't implement them yet. now we can run tests in live neovim sessions. I will add some helper functions to abstract rpcrequest and nvim_feedkeys.

[she3o]

why is git telling me there are 126 conflicting hunks?

[she3o]

Git is like a Rubik's cube; every way I try to resolve this I make it worse. Do you have a solution to this?

[jalvesaq]

Yes, I messed with it yesterday: https://github.com/R-nvim/R.nvim/issues/27#issuecomment-1958571284 I'm sorry for that. You will have to close this PR and manually do it again on this new repository.

Okay
