ExtentReports：使用Hooks无法运行多个测试方案

Question

我正在使用ExtentReports使用Hooks生成NUnit测试报告。当我运行单个测试方案时，它正在通过而没有任何错误。但是，当我尝试同时运行多个方案时，只有第一个测试方案通过了，而其余的都以错误“ OpenQA.Selenium.NoSuchElementException：没有这样的元素：无法定位元素”异常失败。我认为ExtenetReports的Hooks配置与我无法理解正确的配置有关。有人可以帮助我了解成功运行多个测试方案的正确设置吗？

我试图通过运行单个和多个场景来调试代码，发现仅运行单个测试场景就可以了。但是，当我一起运行多个场景时，第一个测试场景成功运行，但是在第二个测试场景中，钩子[AfterStep]下的代码未运行，并且由于此原因，给定的时候，然后代码尝试查找不存在的元素在页面上可用，因此抛出此异常。

OpenQA.Selenium.NoSuchElementException：没有这样的元素：无法找到元素

所有测试方案都应通过且没有任何错误。
