# development/tests/test-coc-register-vim.sh — programmatic coc.nvim
# registration for the Vim client.
#
# nuwiki#lsp#start() registers the language server with coc via coc#config so
# users don't hand-maintain coc-settings.json. This harness stubs coc#config
# (a real autoload/coc.vim on the runtimepath, since Vim's exists('*coc#config')
# goes through the autoload mechanism) to record what nuwiki injects, then runs
# test-coc-register-vim.vim and asserts the payload.
#
# Exit code: 0 when every check passes, 1 on any FAIL or missing output.
# Skips (exit 0) when vim is not installed.
