我的团队正在考虑使用 Selenium 2 进行 UI 测试。我们的 UI 开发由外部供应商完成（另一个主题），使用 RemoteDriver（服务器/客户端）需要更多的维护而不是我们的生产力。
我的测试项目是一个简单的 maven 项目，我尝试启动一个新的 IE(v8 - 64bit)/Firefox/和 Chrome 浏览器，看看它是否会成功导航到某个任意 url。它在我的机器上本地运行，在 TeamCity build-agent 用户配置文件上远程运行（转到源项目并运行 mvn test）。但是，当我尝试通过 TeamCity 控制台（Web 或通过 IntelliJ 上的远程运行）执行测试时，出现以下错误：

我的测试是使用 Cucumber-JVM 设置的，并且在我尝试执行 Selenium 驱动程序的步骤定义中。我肯定会按照 selenium 网站上概述的设置步骤进行操作，但我目前对为什么该项目不通过 TeamCity 执行感到迷茫。
如果这有助于故障排除，我很乐意发送我的测试项目。任何新的见解将不胜感激！
