feat(busted): option to filter tests to run by pattern [wip]

[joeveiga]

This is a step towards being able to run individual tests. See #343.
I'm just starting with lua and vim plugin development as well so, be gentle 😆.

Todo

• Document the changes.
• Fix vim command (not sure how to parse the options correctly or serialize a lua table to be passed down, please see TODOs in the code).

doing a global is technically fine because busted is already run in another process. But can't we do

-- top of the file
local busted_opts

--- ......

mod.run = function(file, opts)
  busted_opts = vim.F.if_nil(opts, {})
-- ...
end

Done, thanks! Although I did a vim.F.if_nil(opts, {}, opts) (3rd arg) 👍

Overall Looks good. Thanks :)

Thanks @Conni2461!
Could you perhaps help me out with some guidance on how to fix the PlenaryBustedDirectory command? I tried modifying the Makefile when testing this to include the filter option in the second argument, but that breaks here:

plenary.nvim/lua/plenary/test_harness.lua

Line 33 in 9f033d1

-- TODO: this is broken if we pass mutliple args!

It seems we're doing some hacking there to parse the second argument as a lua table manually? But adding a second field to the table causes an error. I'm guessing it doesn't like the comma in {minimal_init = 'tests/minimal_init.lua', filter = 'test'}?

EDIT: found this #284
