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: 91. Decode Ways_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0091.Decode-Ways
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question91 struct {
	para91
	ans91
}

// para 是参数
// one 代表第一个参数
type para91 struct {
	one string
}

// ans 是答案
// one 代表第一个答案
type ans91 struct {
	one int
}

func Test_Proble
    
func Test_Problem91(t *testing.T) {

	qs := []question91{

		{
			para91{"12"},
			ans91{2},
		},

		{
			para91{"226"},
			ans91{3},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 91------------------------\n")

	for _, q := range qs {
		_, p := q.ans91, q.para91
		fmt.Printf("【input】:%v       【output】:%v\n", p, numDecodings(p.one))
	}
	fmt.Printf("\n\n\n")
}
