minimal_init.lua

-- This init file is just for testing with [neotest](https://github.com/nvim-neotest/neotest)
--
-- The normal init files are inside tests/environemnts/*.lua
-- However, Neotest by default looks at tests/minimal_init.lua
--
-- In order to run all tests with Neotest, we need to have a minimal init file that includes
-- all possible configurations (Telescope, LSP, etc), hence this file.
