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: 841. Keys and Rooms_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0841.Keys-and-Rooms
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question841 struct {
	para841
	ans841
}

// para 是参数
// one 代表第一个参数
type para841 struct {
	rooms [][]int
}

// ans 是答案
// one 代表第一个答案
type ans841 struct {
	one bool
}

func Test_Problem841(t *testing.T) {

	qs := []question841{

		{
			para841{[][]int{{1}, {2}, {3}, {}}},
			ans841{true},
		},

	
    
func Test_Problem841(t *testing.T) {

	qs := []question841{

		},

		{
			para841{[][]int{{1, 3}, {3, 0, 1}, {2}, {0}}},
			ans841{false},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 841------------------------\n")

	for _, q := range qs {
		_, p := q.ans841, q.para841
		fmt.Printf("【input】:%v       【output】:%v\n", p, canVisitAllRooms(p.rooms))

	fmt.Printf("\n\n\n")
