org.testng.TestNGException: 实例化时出错 class
org.testng.TestNGException: An error occurred while instantiating class
我使用 TestNG 的 selenium 自动化框架在 windows 7 上运行良好，但是当我在 windows 10 上配置相同的框架时，我遇到了以下问题。
你能帮我做同样的事情吗？

您似乎遇到了 java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal 错误。
来自Another Answer:
出现此错误的原因是 xml-apis 库的 1.4.01 版本包含所需的 ElementTraversal class。其他版本如2.0.0、1.0.0等不包含，应用程序编译失败。
- MAVEN 解决方案：
在 pom.xml 处，将 "xml-apis" 依赖项设置为版本 1.4.01:
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
- 其他人的解决方案：
如果不使用maven，可以手动添加xml-apis库，版本1.4.01。你会在 xml-commons 二进制包中找到这些 jar，名为 "XML Commons External 1.4.01"，你可以在这里下载它：http://xerces.apache.org/mirrors.cgi。
最后，使用此版本的库编译并执行 java application/project。
