Webdriver API that captures http traffic

Webdriver API that captures http traffic Dreamer 2/7/12 9:03 AM
All,

I cant seem to capture http request and responses from a webdriver
session. I know you can do this in selenium 1

Selenium s = new DefaultSelenium(...);
s.start("captureNetworkTraffic=true");
s.open("http://www.google.com");
String traffic = s.captureNetworkTraffic("json");

What I'm looking for is a webdriver equivalent. I have had a look at
the proxy class but all that does is emulate/configure  proxy, it does
not capture http traffic


Thanks
Re: Webdriver API that captures http traffic David 2/7/12 12:25 PM
Selenium RC had a captureNetworkTraffic option on startup of browser
session to enable such functionality, though the user of course had to
manually parse the desired data (or look for third party Selenium
tools that did that).

WebDriver unfortunately doesn't natively support this, but you can do
similar with third party tools combined with WebDriver.

Third party solutions to desired feature:

Frankly, it would be nice if WebDriver did incorporate said feature
same as Selenium RC.

Re: Webdriver API that captures http traffic David 2/7/12 5:41 PM
This just got me thinking, maybe not officially incorporated with
WebDriver but could be done as third party work.

If you think of combining WebDriver Firefox extension (used to drive
FirefoxDriver behind the scenes) with some other Firefox extension
that offers HTTP traffic monitoring/analysis, and then expose an API,
you get the requested functionality.

I'm thinking combine WebDriver extension with something like parts of
Firebug (Network tab), liveHttpHeaders, HttpFox, etc.

I made similar suggestion for a related topic on debugger for
JSONWireProtocol (why not incorporate as part of WebDriver Firefox
extension).

RE: [webdriver] Re: Webdriver API that captures http traffic Mark Collin 2/7/12 10:35 PM

I guess the reasons for not doing it are:

 

·         There is no need to do anything, you can already capture network traffic using a proxy.

·         It would not be cross browser and making it cross browser would be a ball ache.

·         Selenium is a browser automation framework, traffic monitoring is not part of its remit.

·         Most people don't want to do traffic monitoring and this won't be used by the vast majority.

The Tamper Data Firefox extension allows a user to save as XML. There
is an example Python based TDParser for this XML here --

Re: Webdriver API that captures http traffic FireGuy 2/8/12 6:29 AM
I've used FiddlerCore for this, it slows things down quite a bit
(almost half the speed with multiple instances working against one
proxy) but for me, the ability to modify requests is worth it.

The only solution that will not be significantly slower, is monitoring
the connections from within the browser, but then, like people said,
you need an implementation for each one.
Re: Webdriver API that captures http traffic David 2/8/12 1:44 PM
On Mark's last comment, understandable why the feature isn't there in
WebDriver. But out of curiosity, was wondering why the traffic option
was added to Selenium RC. Why not just let people use proxies and
third party tools to do the job as they do now with WebDriver. Or did
Selenium RC function differently (than WebDriver in terms of proxies)
requiring that, or was there some other significant reason to add it
back then, or one of the developers just happen to feel like adding
it?

Would be nice to know this background. Otherwise, seems ironic that
feature is in Selenium RC but not WebDriver (unless it is left out due
to not being able to implement same interface/feature due to
architectural difference between the two).

Re: Webdriver API that captures http traffic David 2/8/12 1:45 PM
Andre, thanks for the info on Tamper Data.

Also, regarding Tamper Data, is that a GUI based manual use FF
extension, or is there some API/interface to use it with WebDriver? I
mean do you have to manually save/export the XML and then process it
or you can do that within code together with WebDriver?

Just asking because I made something similar for the "manual" case
using liveHttpHeaders and plain text parsing using Perl (and later
VBScript), quite some time back. It wasn't meant for Selenium/
WebDriver, but could also be used for it. There's also a matching
solution for IE via ieHttpHeaders plugin and my parser.

RE: [webdriver] Re: Webdriver API that captures http traffic Andy Tinkham 2/8/12 3:27 PM
As another point, you can do this already with Firebug like you mentioned - Firebug combined with the NetExport plugin allows our tests to automatically save off HTTP Archive files (which when viewed with a HAR viewer look just like the Net tab in Firebug). Basically, we create a Firefox Profile object before we instantiate the driver, add the two xpis to it, and configure a bunch of options for the plugins (turning on auto export and pointing it at a directory, mostly) and it mostly works well (it currently misses some of our AJAX calls - I think it triggers the export when the page loaded even is fired).

In Ruby, that looks like this:
                      #Add Firebug to Firefox for debugging purposes
                      profile = Selenium::WebDriver::Firefox::Profile.new
                      profile.add_extension(File.join(File.dirname(__FILE__), "firebug-1.9.0-fx.xpi"))
                      profile['extensions.firebug.currentVersion'] = "1.9.0"
                      profile['extensions.firebug.addonBarOpened'] = true
                      profile['extensions.firebug.console.enableSites'] = true
                      profile['extensions.firebug.allPagesActivation'] = "on"
                      profile['extensions.firebug.previousPlacement'] = 1
                      profile['extensions.firebug.onByDefault'] = true
                      profile['extensions.firebug.defaultPanelName'] = "console"
                      profile['extensions.firebug.script.enableSites'] = true
                      profile['extensions.firebug.net.enableSites'] = true
                      profile['extensions.firebug.console.logLimit'] = 50000
                      profile['extensions.firebug.openInWindow'] = true

                      # Add the NetExport Firebug plugin so that we get HAR files showing the performance
                      profile.add_extension(File.join(File.dirname(__FILE__), "netExport-0.8b20.xpi"))
                      profile['extensions.firebug.netexport.alwaysEnableAutoExport'] = true
                      profile['extensions.firebug.netexport.autoExportToFile'] = true
                      profile['extensions.firebug.netexport.autoExportToServer'] = false
                      profile['extensions.firebug.netexport.compress'] = true
                      Dir.chdir(output_dir) { Dir.mkdir "NetExportLogs" unless Dir.exists? "NetExportLogs" }
                      profile['extensions.firebug.netexport.defaultLogDir'] = File.join(output_dir, 'NetExportLogs').gsub("/", '\\')
                      Selenium::WebDriver.for @browser, :profile => profile

(If you try to do this, note the gsub in the next to last line. NetExport seems to be unhappy with forward slashes in the default log directory, but is fine with backslashes. Some of the Firebug preferences probably aren't needed, but  I like having Firebug open as the test runs so I can see errors pop up on the console too if I'm watching.)

We'll probably eventually switch to the BrowserMob proxy in the hopes of getting stats for more browsers than just Firefox, but today is not that day.

Once we get the HTTP Archive files, I've built a script using Jari Bakken's har gem to parse everything out to a database that we can then query across runs.  You could use a standard HAR viewer like that that comes with Jari's gem or the one Jan Odvarko has at softwareishard.com (http://www.softwareishard.com/blog/har-viewer/)

It was never added properly to RC.  

It was only ever available through FireFox and was at best incomplete, I
would regard the RC implementation as a spike that was never removed.
