我在我的mac系统中使用Eclipse Luna Service第2版（4.4.2）。我从市场安装了testng。 当我尝试使用testng.xml 作为Testng套件运行时，我在错误日志窗口中遇到两个错误，并且没有启动testng。但是，如果我在单个类级别运行相同的（不使用testng.xml），它将被正确触发而不会出现问题。

我已尝试过以下选项：
有人建议有没有其他解决方法或解决方案来解决这个问题，还是Eclipse Luna中的错误？ 在此先感谢您的帮助和支持。
答案 0 :(得分：0)
我找到了解决方法，现在通过执行以下步骤来启动我的TestNG套件。
<强>步骤： 右键单击testng.xml - ＆gt;选择Run as-＆gt;选择运行配置 - ＆gt;双击TestNg选项 - ＆gt;浏览套件并从列表中选择相同的testng.xml套件文件。现在单击“运行”按钮，最后我的testng.xml套件即将启动并开始成功运行，没有问题。这种解决方法解决了我的问题。
但是如果我正在查看相同的报告错误（在上面的问题上），如果我正在右键单击相同的testng.xml-＆gt;运行as-＆gt; TestNg套件。我不知道为什么当我直接进行时，testng套件没有启动，但是当我通过运行配置运行时，同样工作正常。
