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: b_test.go
    path of file: ./repos/codeforces-go/misc/nowcoder/63585/b
    
    the code of the file until where you have to start completion: package main

import (
	. "fmt"
	"github.com/EndlessCheng/codeforces-go/main/testutil"
	"github.com/stretchr/testify/assert"
	"io"
	"io/ioutil"
	"path/filepath"
	"strings"
	"testing"
)

var customTestCases = [][2]string{
	{
		``,
		``,
	},
}

func Test(t *testing.T) {
	dir, _ := filepath.Abs(".")
	t.Logf("Current problem is [%s]", filepath.Base(dir))

	if len(customTestCases) > 0 && strings.TrimSpace(customTestCases[0][0]) != "" {
		tarCase := 0 // -1
		testutil.AssertEqualStringCase(t, customTestCases, tarCase, run)
		t.Log("======= custom =======")
	}

	tarCase := 0 // -1
	testutil.AssertEqualFileCaseWithName(t, dir, 
    
func TestCheck(_t *testing.T) {
	return
	assert := assert.New(_t)
	_ = assert

	testutil.DebugTLE = 0

	inputGenerator := func() (string, testutil.OutputChecker) {
		rg := testutil.NewRandGenerator()
		rg.One() // 若不是多测则 remove
		n := rg.Int(1, 5)
		rg.NewLine()
		a := rg.IntSlice(n, 0, 5)
		return rg.String(), func(myOutput string) (_b bool) {
			// 检查 myOutput 是否符合题目要求
			// * 最好重新看一遍题目描述以免漏判 *
			// 对于 special judge 的题目，可能还需要额外跑个暴力来检查 myOutput 是否满足最优解等
			in := strings.NewReader(myOutput)

			myA := make([]int, n)
			for i := range myA {
				Fscan(in, &myA[i])
			}
