尝试使用Nunit运行多个Selenium Webdriver测试失败

Question

我想知道是否有人可以帮助我。我在C＃和Nunit上使用selenium Webdriver，当我尝试运行多个测试时，我收到以下错误：

  

OpenQA.Selenium.WebDriverException：意外错误。 System.Net.WebException：无法连接到远程服务器---＆gt; System.Net.Sockets.SocketException：无法建立连接，因为目标计算机主动拒绝它127.0.0.1:7055      在System.Net.Sockets.Socket.DoConnect（EndPoint endPointSnapshot，SocketAddress socketAddress）

当我以个人身份运行这些测试时，他们正在运行并且传递正常。

任何帮助或指针都会很棒。

以下是我的代码和我的驱动程序类的示例
