:echo mapleader
If it shows undefined then you need to set the mapleader
add the following line to your ~/.vimrc
let mapleader=","
and then add the following to the ~/.vimrc
au FileType go nmap <leader>r <Plug>(go-run)
au FileType go nmap <leader>b <Plug>(go-build)
au FileType go nmap <leader>t <Plug>(go-test)
au FileType go nmap <leader>c <Plug>(go-coverage)
this is to set Mapleader + r will run the go file and Mapleader + b will build the file
in this case the mapleader is comma(,) , so the command comma + r will run the file and comma + t will run the test
