我正在尝试使用 ITest 接口为来自数据提供者的测试获取自定义名称（用于 Jenkins 报告）。我尝试了一个类似下面的示例程序，以了解 TestNG 在什么时候调用 gettestname() 方法。

粘贴输出和程序。

正如您在下面看到的，输出令人困惑，并且在某些地方测试名称也为“空”。所以我的问题是 Itest 是否设计为与数据提供者一起使用？此外，当我们使用 parallel=true 运行以下数据提供程序时，它会变得更加混乱，因为成员 'testName' 是跨线程共享的，并且只有一个类实例正在运行。

我可以看到 ITest 如何与 @factory 一起使用，因为当我们使用工厂时，每个测试方法运行都会调用一个新的 TestClass，所以那里不会有问题。

输出：

TestNGThreadingTest:43 - Before Method Thread id = 1 TestName = test1

这是一个并发问题（也许是 TestNG 问题？）。

替换String testName为ThreadLocal<String> testName = new ThreadLocal()应该可以解决您的问题。

或者你也可以使用一个@Factory链接到的@DataProvider，但@Factory 可能不能并行工作。
