Question

使用下面提到的代码，如果测试用例通过截屏已成功捕获并显示在报告中。但是当测试失败时 - 屏幕截图不会显示。甚至屏幕截图超链接也不会显示在报告中。任何人都可以理清代码中的错误？

      }

      @Override
      public void onTestSkipped(ITestResult result) {
      // will be called after test will be skipped
        Reporter.log("Skip");
      }
      @Override

      // will be called after test will pass
        Reporter.log("Pass");
      }

}

您的onTestFailure方法未被调用，因为您没有为测试类指定侦听器。您缺少@Listeners注释中的值。它应该像

@Listeners({CountryChoserLayer.class})

您可以在official TestNg's documentation中找到更多指定侦听器的方法。

在尝试在onTestFailure方法中截取屏幕截图时，您可能遇到的另一个问题是NullPointerException。最简单的解决方法是将驱动程序字段的声明更改为静态。我使用这些修复程序运行代码，并获得带有屏幕截图的报告。

我必须补充一点，在我看来，将测试和听众方法都放在一个类中并不是一个好习惯。

Selenium Web驱动程序 - 失败屏幕截图未在TestNG报告中捕获
