[Selenium] 如何起Driver的时候加header？

我们的automation中有这样一个scenario：

Given a user with user agent "Googlebot/2.X (+http://www.googlebot.com/bot.html)"
Given an ad in category "Children's Books" and waiting for indexing           
When I navigate to browse "Children's Books" in "Australia"          
And I click on the first ad in SearchPage
Then I should see element "lnkVIP_SeeAllResultsOnTop" in ViewItemPage          
And I should see text "You may also be interested in..." in ViewItemPage

在第一步的时候，特别慢，然后从log中看，都是用于去连接browsermob server. 原来以前对于这类case，由于Chrome和FF都不支持直接加header， 所以我们的实现方式，是通过外加proxy —— browsermob来实现的。code如下：

 @Given("a user with user agent \"$useragent\"")
 public void givenUserWithUserAgent(String useragent)throws Exception {
	trackHelper.set(new TrackingHelper());       
	WebUXDriver.getWebUXDriver().setTrackingHelper(trackHelper.get());        
	trackHelper.get().setHeader("User-Agent", useragent);        
	trackHelper.get().init();            
 }

TrackingHelper:

   

     public void init()throwsException { 
           WebUXDriver.getWebUXDriver().setUseTracking(true);        
	   if(runMode.equals("ExistingGrid")) {            
	   // connect to proxy server            
	       socket = newSocket(TrackingPortFactory.PRODXY_MACHINE_IP, TrackingPortFactory.PROXY_MACHINE_PORT);            
		   System.out.println("Start to connect to proxy server...");            
	       socket.setSoTimeout(TIME_OUT);            
	       ips = socket.getInputStream();            
	       ops = socket.getOutputStream();            
	       dos = newDataOutputStream(ops);           
	       brNet = newBufferedReader(newInputStreamReader(ips));        
	   }    
	}

其实这个地方，我们只是想加个header, 完全没必要借助于browsermob，于是改了一下code：

    #browser=*phantomjs
    #header=User-Agent||Googlebot/2.X (+http://www.googlebot.com/bot.html)   
       Given a user      
       When I navigate to browse "Children's Books" in "Australia"   
       And I click on the first normal ad in SearchPage   
       Then I should see element "lnkVIP_SeeAllResultsOnTop" in ViewItemPage   
       And I should see text "You may also be interested in..." in ViewItemPage
 
  
 
  
 
  
这里用到了browser —— phantomjs, 这个具体可以google一下。加header:
 
  
 
  
   DesiredCapabilities capability = DesiredCapabilities.phantomjs();
   capability.setCapability("phantomjs.page.customHeaders." + name, value);
   driver = createRemoteWebDriver(url, capability);
 
  
 
  
再run这个case的时候，时间节约了将近一半，不过这个仅仅针对加header这样简单的request，如果想并发跑tracking类的case，还是需要借助browsermob。
