Run golang tests in vim.
Add this to your .vimrc or inside .vim/ftplugin/go.vim if you want only use this mapping with files that have the go filetype.
map <Leader>ra :wa<CR> :GolangTestCurrentPackage<CR>
map <Leader>rf :wa<CR> :GolangTestFocused<CR>GolangTestFocused will find the first func above your current line that starts with Test and run that with go test -run <test name>. If you're using examples this plugin will use -examples.run rather than -run.
This plugin assumes you will be testing the local package. For example if you run GolangTestCurrentPackage the resulting command would be: go test -v ..
With vim-bundle: vim-bundle install benmills/vimux-golang
Otherwise download the latest tarball, extract it and move plugin/vimux-golang.vim inside ~/.vim/plugin. If you're using pathogen, then move the entire folder extracted from the tarball into ~/.vim/bundle.
