	"fmt"
	"os"
	"testing"
)


func TestWritecardnames(t *testing.T) {
	var cardnames []string
	Writecardnames(&cardnames)
	fmt.Println(cardnames)
	// 创建一个CSV文件
	fileName := "output29.csv"
	file, err := os.Create(fileName)
	if err != nil {
		fmt.Println("Error creating file:", err)
		return
	}
	defer file.Close()

	// 创建一个csv.Writer
	writer := csv.NewWriter(file)
	defer writer.Flush()

	// 写入字符串数组到CSV文件
	if err := writer.Write(cardnames); err != nil {
		fmt.Println("Error writing record to csv:", err)
		return
	}

	// 检查是否有错误发生
	if writer.Error() != nil {
		fmt.Println("Error:", writer.Error())
	} else {
		fmt.Println("CSV file has been written successfully.")
	}
}
