You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: name_list_test.go
    path of file: ./repos/seaweedfs/weed/util/skiplist
    
    the code of the file until where you have to start completion: package skiplist

import (
	"math/rand"
	"strconv"
	"testing"
)

const (
	maxNameCount = 100
)

func String(x int) string {
	return strconv.Itoa(x)
}

func TestNameList(t *testing.T) {
	list := newNameList(memStore, 7)

	for i := 0; i < maxNameCount; i++ {
		list.WriteName(String(i))
	}

	counter := 0
	list.ListNames("", func(name string) bool {
		counter++
		print(name, " ")
		return true
	})
	if counter != maxNameCount {
		t.Fail()
	}

	// list.skipList.println
    
func TestNameList(t *testing.T) {
	list := newNameList(memStore, 7)

	for i := 0; i < maxNameCount; i++ {
		list.WriteName(String(i))
	}

	counter := 0
	list.ListNames("", func(name string) bool {
		counter++
		print(name, " ")
		return true
	})
	if counter != maxNameCount {
		t.Fail()
	}

	// list.skipList.println()

	deleteBase := 5
	deleteCount := maxNameCount - 3*deleteBase

	for i := deleteBase; i < deleteBase+deleteCount; i++ {
		list.DeleteName(String(i))
	}

	counter = 0
	list.ListNames("", func(name string) bool {
		counter++
		return true
	})
	// list.skipList.println()
	if counter != maxNameCount-deleteCount {
		t.Fail()
	}

	// randomized deletion
	list = newNameList(memStore, 7)
	// Delete elements at random positions in the list.
	rList := rand.Perm(maxN)
	for _, i := range rList {
		list.WriteName(String(i))
	}
	for _, i := range rList {
		list.DeleteName(String(i))
	}
	counter = 0
	list.ListNames("", func(name string) bool {

		print(name, " ")
		return true
	})
	if counter != 0 {
		t.Fail()
	}
