testNg执行并行执行的多个类的不稳定行为：SeleniumWebdriver + TestNG

问题描述 投票：0回答：1

请查看testng.xml，请提出建议 我想运行2个课程（如下所述），但面临一些挑战，因为它显示了2种情况下的一些不稳定的行为，如下所述。

设置和说明：

  1. 有2个测试类：1。HomepageTest＆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。在执行时，它启动主页[在窗口1]>执行Homepagetest的[Pri​​ority1]> 然后启动SignInPage [On Window2（此处窗口1也打开）] >>并执行SignIntest的[priority1] == >>之后执行HomepageTest的[priority2]和 SigninTest的[priority2]等等.. [即执行优先在主页和SignInpage之间切换] [参考问题1]

1.2。执行完成后，关闭1个窗口（主页） 但无法关闭其他浏览器（SigninPage） [这里所有打开的窗户应该关闭但是1关闭，1仍然打开] [参考问题2] ****场景2：**当我使用threadcount = 2时： ** 行为： 2.1。它在chrome上同时打开2个窗口 - 在一个窗口中它启动URL（对于URL等待10秒） 但在第二个窗口中它不会启动任何URL（在整个测试过程中保持空白）

2.2：执行就像上面提到的1.1一样。 所有执行都在1个窗口进行， 另一个窗口（空白窗口）在整个测试过程中保持空闲状态。甚至没有URL被分配给它

2.3执行完成后，它只关闭执行正在执行的1个窗口 即它无法关闭没有启动URL的窗口

问题1：[两种方案]为什么执行不是基于组。 它基于1.1中提到的优先级运行，看起来不正确。

理想情况下，它应该执行testClass1的Group1和2 那么它应该关闭那个窗口然后应该启动第二个窗口并运行Group1和2测试，然后关闭该窗口

问题2：[两种方案]为什么它无法关闭1浏览器。我使用了活动窗口 窗口句柄和计数返回1，而它应该是2因为webdriver已打开2个窗口

问题3：[针对第二场景]当线程数= 2时，为什么它会启动一个空白窗口 （如2.1中所述）

在决定使用并行执行时，请确保不使用多个线程共享您正在使用的资源。并且还要确保它们不可改变以增加安全性。 driverObj是静态的，可以同时被所有测试类访问，并且是导致问题的根本原因。您可以通过在测试方法中创建和初始化驱动程序并安全地传递它来保持简单。另一个稍微复杂的方法是使用ThreadLocal

而对于优先级，这就是当前行为首先运行优先级较高的测试，然后是降低优先级的测试，即使没有优先级，也不会保证执行顺序。
