如何配置PhantomJSDriver尽可能接近我的Google Chrome浏览器？

以下是我的开发环境的详细信息：

-Visual Studio 2012 Ultimate更新4

-谷歌浏览器版本40.0.2214.94 m

-具有32位操作系统的Windows 7 Professional

我的Google Chrome浏览器的用户代理字符串是：

Mozilla / 5.0（Windows NT 6.1）AppleWebKit / 537.36（KHTML，例如Gecko）Chrome / 40.0.2214.94 Safari / 537.36

我的自动UI测试代码中的C＃代码如下：

var options = new PhantomJSOptions();

// Chrome User Agent ( Chrome Version 40.0.2214.94 m ) 
options.AddAdditionalCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36");

driver = new OpenQA.Selenium.PhantomJS.PhantomJSDriver(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..\..\packages\PhantomJS.1.9.8\tools\phantomjs"), options);

url = new Uri("http://localhost:2816/");

IWait<IWebDriver> wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(90.00));

wait.Until(ExpectedConditions.ElementIsClickable( By.XPath("//a[text()='Users']")));

IWebElement btn = waitArg.Until<IWebElement>((d) => {
 try{ 
 return d.FindElement( By.XPath("//a[text()='Users']") );
 }
 catch {

        return null;
    }  
  });

  btn.Click();

不幸的是，上面的代码很难找到元素。我相信，如果我可以配置代码中使用的PhantomJS驱动程序，以更紧密地模拟桌面上的Google Chrome版本40.0.2214.94 m浏览器，那么只要有时间，自动UI测试代码就应该能够提供更一致，更准确的测试结果测试运行。

有人可以建议我是否可以对以下代码进行一些修改，使其更接近于我的Google Chrome版本40.0.2214.94 m浏览器？

var options = new PhantomJSOptions();

// Chrome User Agent ( Chrome Version 40.0.2214.94 m ) 
 options.AddAdditionalCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36");

 driver = new OpenQA.Selenium.PhantomJS.PhantomJSDriver(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..\..\packages\PhantomJS.1.9.8\tools\phantomjs"), options);

在@ artjom-b的帮助下更新答案

        var options = new PhantomJSOptions();

        options.AddAdditionalCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36");


        var service = PhantomJSDriverService.CreateDefaultService(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..\..\packages\PhantomJS.1.9.8\tools\phantomjs"));

        service.SslProtocol = "any";
        driver = new PhantomJSDriver(service, options);
        url = new Uri("http://localhost:2816/");

        // 1280, height: 1024
        // @artjom-b strongly recommened that the Driver's Window Size be quite large.  Let's set the Window Size to quite large. 
        driver.Manage().Window.Size = new System.Drawing.Size(1280, 1024); // Size is a type in assembly "System.Drawing"
