can not print when the case success

[jianfengye]

about "Use the -print-all parameter to print a list of all specs: go test -print-all Otherwise only the failing specs are printed"

i find it does not work if i print "go test tester -print-all"

my example like this:
package hello

import (
"gospec"
"testing"
"fmt"
)

func TestAllSpecs(t *testing.T) {
fmt.Println("testing")
r := gospec.NewRunner()
r.AddSpec(HelloSpec)
gospec.MainGoTest(r, t)
}

anything wrong?

i found the solution:
use go test tester -v
