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: 16. 3Sum Closest_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0016.3Sum-Closest
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question16 struct {
	para16
	ans16
}

// para 是参数
// one 代表第一个参数
type para16 struct {
	a      []int
	target int
}

// ans 是答案
// one 代表第一个答案
type ans16 struct {
	one int
}

func Test_Problem16(t *testing.T) {

	qs
    
func Test_Problem16(t *testing.T) {

	qs := []question16{

		{
			para16{[]int{-1, 0, 1, 1, 55}, 3},
			ans16{2},
		},

		},

		{

	}

	fmt.Printf("------------------------Leetcode Problem 16------------------------\n")
