Question

注意

仅从更新TestNG版本后，问题才开始出现 6.8.8至TestNG 6.11
即使使用最新版本的TestNG 7.0.0-beta1和 maven surefire 3.0.0-M1
问题是断断续续的，即使在所有运行中也无法复制具有完全相同的套件，测试和参数
NPE仅在所有测试完成后才发生，并在执行@AfterSuite方法之前出现。
测试由在网格上运行的硒脚本组成。

不太确定为什么这个问题不能总是重现，以及为什么显然（基于strack跟踪）测试在TestNG的XmlSuite类中返回null。即使不使用任何自定义侦听器，也会出现问题

用于surefire和testng的POM.xml配置：

当使用surefire运行时，TestNG NPE：org.testng.xml.XmlSuite.getAllParameters（XmlSuite.java:434）处出现间歇性NullPointerException
