嗨冠军！ 到目前为止，我们在报告方面已经涵盖了很多基础，您已经达到了高潮文章。 如果要将 HTML 报告附加到电子邮件并将其发送给利益相关者，则生成 HTML 报告可能没有帮助。 由于 ANT 生成的 JUnit 报告具有 index.html 文件，该文件又嵌入了其他一些 HTML 文件，例如 overview-frame.html，所有类-frame.html 和 overview-summary.html 文件。
在这种情况下我们该怎么办？ 我们如何将其附加到电子邮件？ 我们不能将其作为单个文件而不是一组 HTML 文件获得吗？ –所有这些问题的唯一答案是，生成一个 **PDF 文件**。
在这种情况下我们该怎么办？ 我们如何将其附加到电子邮件？ 我们不能将其作为单个文件而不是一组 HTML 文件获得吗？ –所有这些问题的唯一答案是，生成一个 **PDF 文件**。
让我们看看在不干扰我们到目前为止所做的[定制](https://javabeginnerstutorial.com/selenium/10c-advanced-webdriver-junit-report-customization/)的情况下生成 PDF 报告的过程，
**java2word-3.3.jar** -帮助我们创建 Word 文档并以所需方式对其进行操作。
**xstream-1.3.1.jar** –处理图片
**xstream-1.3.1.jar** –处理图片
让我们继续从 [https://code.google.com/archive/p/java2word/downloads](https://code.google.com/archive/p/java2word/downloads) （在撰写本文时的下载位置）下载这两个 JAR 文件。 我还将这些 JAR 以及本文中处理的所有其他代码文件一起放在我们的 [GitHub 存储库](https://github.com/JBTAdmin/Selenium)中。
