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: Solution_test.go
    path of file: ./repos/awesome-golang-algorithm/leetcode/701-800/0799.Champagne-Tower
    
    the code of the file until where you have to start completion: package Solution

import (
	"reflect"
	"str
    
func TestSolution(t *testing.T) {
	//	测试用例
	cases := []struct {
		name      string
		q, qr, qg int
		expect    float64
	}{
		{"TestCase1", 1, 1, 1, 0},
		{"TestCase2", 2, 1, 1, 0.5},
		{"TestCase3", 4, 2, 2, 0.25},
		{"TestCase4", 100000009, 33, 17, 1.0},
	}

	//	开始测试
	for i, c := range cases {
		t.Run(c.name+" "+strconv.Itoa(i), func(t *testing.T) {
			got := Solution(c.q, c.qr, c.qg)
			if !reflect.DeepEqual(got, c.expect) {
				t.Fatalf("expected: %v, but got: %v, with inputs: %v %v %v",
					c.expect, got, c.q, c.qr, c.qg)
			}
		})
	}
}
