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: a_test.go
    path of file: ./repos/codeforces-go/misc/nowcoder/63585/a
    
    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/
    
func TestCompare(_t *testing.T) {
	return
	testutil.DebugTLE = 0

	inputGenerator := func() string {
		//return ``
		rg := testutil.NewRandGenerator()
		rg.One() // 若不是多测则 remove
		n := rg.Int(1, 3)
		rg.NewLine()
		rg.IntSlice(n, 1, 5)
		return rg.String()
	}

	// 暴力算法
	runBF := func(in io.Reader, out io.Writer) {
		solve := func(Case int) {

		}

		T := 1
		Fscan(in, &T) //
		for Case := 1; Case <= T; Case++ {
			solve(Case)
		}

		_leftData, _ := ioutil.ReadAll(in)
		if _s := strings.TrimSpace(string(_leftData)); _s != "" {
			panic("有未读入的数据：\n" + _s)
		}
	}

	// 先用 runBF 跑下样例，检查 runBF 是否正确
	dir, _ := filepath.Abs(".")
	testutil.AssertEqualFileCaseWithName(_t, dir, "in*.txt", "ans*.txt", 0, runBF)
	//testutil.AssertEqualStringCase(t, customTestCases, 0, runBF)
	return

	testutil.AssertEqualRunResultsInf(_t, inputGenerator, runBF, run)

	// for hacking, write the hacked codes in runBF
	//testutil.AssertEqualRunResultsInf(_t, inputGenerator, run, runBF)
}
