var PrepareCmd = func(cmd *exec.Cmd) Runnable {
	return &cmdWithStderr{cmd}
}

PrepareCmd extends exec.Cmd with extra error reporting features and provides a hook to stub command execution in tests

func SetPrepareCmd(fn func(*exec.Cmd) Runnable) func()

SetPrepareCmd overrides PrepareCmd and returns a func to revert it back

type CmdError struct {
	Stderr *bytes.Buffer
	Args   []string
	Err    error
}

CmdError provides more visibility into why an exec.Cmd had failed

func (e CmdError) Error() string

type Runnable interface {
	Output() ([]byte, error)
	Run() error
}

Runnable is typically an exec.Cmd or its stub in tests
