并行完成多个类的testNg执行中的异常行为：SeleniumWebdriver + TestNG

Question

请查看testng.xml并提出建议
我想运行2个类（如下所述），但由于在下面提到的2个方案下显示出一些不稳定的行为，因此面临一些挑战。

设置和说明：

1. 有2个测试类：1. HomepageTest和SignIntest
   

2. 这些测试类下的方法具有组和优先级
   **目标是使用
   

组运行这些测试

场景1：：当我使用Threadcount = 1时；
[test name =“ AutoPracticee” parallel =“ classes” thread-count =“ 1”]

以下是行为：

1.1。执行时，它会启动Homepage [在window1上]>执行Homepagetest的[Pri​​ority1]>
，然后启动SignInPage [在Window2 （此处也打开了窗口1）] >>并执行[priority1]的SignIntest
== >>此后，它将执行HomepageTest的[priority2]和SigninTest的
[priority2]等。.
[即，执行将在优先级的Homepage和SignInpage之间切换]
[请参阅问题1]

1.2。执行完成后，它将关闭1个窗口（主页）
，但无法关闭另一个浏览器（SigninPage）
[此处所有打开的窗口都应关闭，但1个关闭，而1个保持打开状态]   [请参阅问题2]

****方案2：**当我使用threadcount = 2时：
**
行为：
2.1。它在chrome上同时打开2个窗口-在一个窗口中启动URL（URL等待10秒）
但是在第二个窗口中，它不启动任何URL（在整个测试过程中保持空白）

2.2：执行与上述1.1相同。
所有执行都在一个窗口上进行，
在整个测试过程中，另一个窗口（空白窗口）保持空闲状态。甚至没有为URL分配

2.3执行完成后，它仅关闭正在执行执行操作的1个窗口
也就是说，它无法关闭没有启动URL的窗口

问题1：[针对两种情况] 为什么执行不是基于组的。
它在1.1中提到的优先级基础上运行，这看起来是不正确的。

理想情况下，它应该执行testClass1的Group1＆2
然后应该关闭该窗口，然后启动第二个窗口并运行Group1＆2测试，然后关闭该窗口

问题2：[针对两种情况] 为什么无法关闭1个浏览器。我使用
窗口句柄计算了活动窗口，计数返回1，而应为2，因为webdriver打开了2个窗口

问题3：[用于第二种情况] ：当线程数= 2时，为什么它启动空白窗口
（如2.1中所述）

Answer 1

在决定使用并行执行时，请确保所使用的资源没有在多个线程之间共享。并确保它们是不变的，以提高安全性。 driverObj是静态的，并且所有测试类都可以同时访问它，这是问题的根本原因。您可以通过在测试方法内部创建和初始化驱动程序并将其安全传递来简化操作。另一种稍微复杂的方法是使用ThreadLocal

对于优先级，这是当前行为，即先运行高优先级测试，然后再运行低优先级测试和iirc，即使没有优先级，也不能保证执行顺序。
