【问题描述】：
我正在尝试在 Linux 机器上运行 selenium webdriver。所以我尝试使用 HtmlUnitDriver 来实现这一点。
执行 jquery 时出现以下错误。
TypeError: Cannot find function addEventListener in object [object HTMLDocument]. (http://localhost/xxx/js_lib/jquery2/jquery-2.1.0.min.js#2)
当HtmlunitDriver在没有以下任何浏览器版本的情况下使用时会发生上述异常，
HtmlUnitDriver driver = new HtmlUnitDriver();
driver.setJavascriptEnabled(true);
由于以下原因，junit 测试用例也失败了，
org.openqa.selenium.NoSuchElementException: Unable to locate element with ID: abcde
如果我通过如下浏览器版本，
HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_38);
driver.setJavascriptEnabled(true);
测试用例正在通过，但在控制台中抛出异常，例如，

我有以下问题列表，
- 要在 HtmlUnitDriver 中使用 firefox 浏览器，我需要在 Linux 机器上安装 firefox 吗？
- 为什么会抛出上述异常？
- 是否有任何选项可以在没有 GUI 的 lunix 机器上运行 selenium？
我是 selenium 的初学者，需要您对此提出宝贵的意见。谢谢
