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: gpt3_test.go
    path of file: ./repos/feishu-openai/code/services/openai
    
    the code of the file until where you have to start completion: package openai

import (
	"context"
	"fmt"
	"testing"
	"time"

	"start-feishubot/initialization"
)

func TestCompletions(t *testing.T) {
	config := initialization.LoadConfig("../../config.yaml")
	msgs := []Messages{
		{Role: "system", Content: "你是一个专业的翻译官，负责中英文翻译。"},
		{Role: "user", Content: "翻译这段话: The assistant messages help store prior responses. They can also be written by a developer to help give examples of desired behavi
    
func TestCompletions(t *testing.T) {
	config := initialization.LoadConfig("../../config.yaml")

	}
	gpt := NewChatGPT(*config)
	resp, err := gpt.Completions(msgs, Balance)
	if err != nil {
		t.Errorf("TestCompletions failed with error: %v", err)
	}
	fmt.Println(resp.Content, resp.Role)
