@FedeDP cmd := exec.Command("ls", "-o stratum+tcp", "-u user", "-p pass")
cmd.Run() always throws an error because this command fails every time.
If we return error then test wont pass due to error even still the rule triggers

Irrespective of whether ls command fails or not the rule gets triggered. So there is no need to return the error
