Tester

This template is for testing the output of commands.
Place the output what you are expecting between characters of general comment (at the end of the template), and add the arguments in exec.Command, if it is needed to run the command.

If you use Gowizard: gowizard -tester
Else, use this template in "<Go project>/<name>_test.go"

	"fmt"
	"log"

	out, err := exec.Command(EXEC).Output()
	if err != nil {
		log.Fatal(err)
	}
	fmt.Print(string(out))

	// Output:
