如何用apache-poi java编写将数据写入word文档的类的单元测试？

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>

import org.apache.poi.xwpf.usermodel.*;
import org.junit.jupiter.api.Test;

import java.io.FileOutputStream;
import java.io.IOException;

public class WordWriterTest {

    @Test
    public void testWriteDataToWord() {
        // 创建一个新的Word文档
        XWPFDocument document = new XWPFDocument();

        // 创建一个段落
        XWPFParagraph paragraph = document.createParagraph();

        // 创建一个运行
        XWPFRun run = paragraph.createRun();

        // 设置运行的文本内容
        run.setText("Hello, World!");

        // 保存文档到指定路径
        try (FileOutputStream out = new FileOutputStream("output.docx")) {
            document.write(out);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
