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: config_test.go
    path of file: ./repos/go-doudou/framework/registry/memberlist
    
    the code of the file until where you have to start completion: package memberlist

import (
	"github.com/unionj-cloud/go-doudou/v2/framework/config"
	"github.com/unionj-cloud/go-doudou/v2/toolkit/memberlist"
	"os"
	"testing"
)

func TestMain(m *testing.M) {

    
func Test_setGddMemRetransmitMult_unset(t *testing.T) {
	config.GddMemRetransmitMult.Write("")
	type args struct {
		conf *memberlist.Config
	}
	tests := []struct {
		name string
		args args
	}{
		{
			name: "",
			args: args{
				conf: newConf(),
			},
		},
	}
	for _, tt := range tests {
		t.Run(tt.name, func(t *testing.T) {
			setGddMemRetransmitMult(tt.args.conf)
		})
	}
}
