我正在尝试使用Webdriver和无头浏览器，并遇到了一些困难。遗憾的是，我不能分享我的所有代码，但我可以展示我是如何设置它的。因此，让我先说一下我尝试实现的基本用例，我使用chrome驱动程序来确保它不是像一个糟糕的xpath那样平凡，而且脚本运行得很好。下面是我正在初始化htmlunit的方法，其中有一些是出现的许多错误
HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME)
driver.setJavascriptEnabled(true)
在我的登录页面上使用htmlunit驱动程序就像一个冠军，一旦我到达应用程序的主页但事情就会崩溃。

除此之外，我收到了大量的警告：

我怀疑由于所有这些错误，我的javascript实际上并没有加载。为了验证这一点，当我使用Chrome运行测试时，我在主页面上获取了页面源代码，然后使用HtmlUnit做了同样的事情，这证实了我的怀疑。没有javascipts生成的html存在。我们的网站使用JQuery，Knockout和其他几个插件，所有库都是相当常见的地方，没有一个是chrome驱动程序的问题，或者在我运行应用程序时在dev工具控制台中引发任何类型的错误。任何帮助将不胜感激。
