As already mentioned sync.WaitGroup is a right way in production code. But when developing for test and debug purposes you can just add select{} statement at the end or the main().

func main(){
    go routine()
    ...
    select{}
}

main() then never returns and you would kill it with for example Ctrl-C. It isn't idiomatic, never used in production, but just very quick easy hack when developing.
