TestNg子类中没有调用父类的@AfterClass

Question

        I  have a similar issue and need help to understand if my code needs any restructuring.  The issue is for the second test SeleniumDragnDrop, the browser does not close.

我有一个使用驱动程序类实例化 WebDriver 的父类和具有 @Test 方法的子类。

问题是第二次测试 SeleniumDragnDrop 时，浏览器未关闭。 Debuggnig 向我显示 @AfterClass 没有被调用。从这个测试的 logger.info 也没有被记录这一事实也可以看出。下面记录跟踪。 @BeforeClass 被调用

17:23:40.558 [TestNG-test=SeleniumTrials-1] INFO  selenium.trials.SeleniumDragnDrop - Before Class: Setup Thread ID: 23

课后不会出现任何记录。查看此日志跟踪..

Answer 1

问题是测试 SeleniumDragnDrop 有 @AfterTest 方法，该方法正在关闭会话。因此 @AfterClass 没有被调用。删除@AfterTest后，它工作正常
