Else, use this template in "<Go project>/<name>_test.go"

package main

import (
	"fmt"
	"log"
	"os"
	"os/exec"
	"path/filepath"
)

var EXEC string

	var err error
	log.SetFlags(0)
	log.SetPrefix("ERROR: ")

	// The executable name will be the directory name.
	if EXEC, err = os.Getwd(); err != nil {
		log.Fatal(err)
	}
	EXEC = filepath.Base(EXEC)

	if _, err = exec.LookPath(EXEC); err != nil {
		if err.(*exec.Error).Err == exec.ErrNotFound {
			if err = exec.Command("go", "install").Run(); err != nil {
				log.Fatal(err)
			}
		} else {
			log.Fatal(err)

	}
}

func Example() {
	out, err := exec.Command(EXEC).Output()
	if err != nil {

	fmt.Print(string(out))

	// Output:
