当我们使用TestNG数据提供程序而不是工厂时，ITest工作吗

我正试图使用ITest接口从数据提供商处获取Jenkins报告的自定义名称，以供我的测试使用。我尝试了下面这样的示例程序，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，输出是令人困惑的，有些地方的测试名称也是“null”。所以我的问题是Itest是否设计用于数据提供者？另外，当我们使用parallel=true运行下面的dataprovider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在运行

我可以看到ITest如何与@factory一起使用，因为当我们使用factories时，每个testmethod运行都会调用一个新的TestClass，所以这不会是一个问题

输出：

代码：

这是一个一致性问题，也许是一个测试问题

通过ThreadLocal testName=new ThreadLocal重新放置字符串testName可以解决您的问题

或者您也可以使用链接到@DataProvider的@Factory，但是@Factory。

我在这里没有看到任何问题。预期的行为是什么？我的问题是我们是否可以使用这个ITest特性，即提供自定义名称和数据提供程序？……我可以理解它们与@factory一起正常工作，因为对于每个条目，都使用了一个新的测试类实例。我还看到在初始化测试名称的before方法之前调用了gettestname。在aftermethod之前还有一些额外的调用…TestNG确切地使用哪些调用来确定测试的名称？您的输出告诉我们ITest正在使用数据提供程序：PASSED:test1test1。如果没有ITest，显示将不一样。啊，我的坏…但是我在dataprovider注释中使用parallel=true运行，结果不同。我用输出更新了问题部分。好的，我看到问题了。但是现在，我们需要所有的输出来查看testng何时调用what；棒极了，它的工作和感谢其他信息！
