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: 2180. Count Integers With Even Digit Sum_test.go
    path of file: ./repos/LeetCode-Go/leetcode/2180.Count-Integers-With-Even-Digit-Sum
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question2180 struct {
	para2180
	ans2180
}

// para 是参数
// one 代表第一个参数
type para2180
    
func Test_Problem1(t *testing.T) {

	qs := []question2180{
		{
			para2180{4},
			ans2180{2},
		},

		{
			para2180{30},
			ans2180{14},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 2180------------------------\n")

	for _, q := range qs {
		_, p := q.ans2180, q.para2180
		fmt.Printf("【input】:%v       【output】:%v\n", p, countEven(p.target))
	}
	fmt.Printf("\n\n\n")
