When run lua -lluacov test.lua command-line, the error message is:

lua: module 'luacov' not found:
    no field package.preload['luacov']
    no file './luacov.lua'

I usedluarocks --lua-dir=(brew --prefix)/opt/lua@5.1 install luacov command to install 5.1 version.

Try running luarocks show luacov to see where the files are installed, and luarocks path to output path variables that match your LuaRocks installation. You can use eval $(luarocks path) to export the variables to your shell session, and lua -e 'print(package.path)' to inspect what is the package path currently configured for your Lua interpreter.

It works for me. Thank you.
