Can I automate Chrome request blocking using Selenium-webdriver for Ruby?

I am a QA automation analyst responsible for testing a multi-platform online banking application. For our automation testing we use RubyMine suite with Gherkin/Cucumber, Ruby-scripted steps and Selenium-webdriver, Watir and page-object gems/libraries.

I have a number of scripts that I cannot automate completely without manual intervention, and these include blocking certain network calls through Telerik Fiddler to produce warning pages or error messages, etc. The future of our automation would be to do this through RubyMine instead of Fiddler for network blocking. I know there is a way to do this in Chrome using Inspect Element and the Network menu using enable request blocking. However, I cannot figure out a way to force Chrome through Ruby/Selenium to block a given request. The only way is do manually do it myself, and therefore I can't actually automate these as wanted.

So, my question -- is this a possibility to automate request-blocking with Selenium-webdriver? And, if so, where should I begin to look for help with this?

Thanks.

To block URLs from loading with Selenium with the DevTool API:

def send_cmd(driver, cmd, params={})
  bridge = driver.send(:bridge)
  resource = "session/#{bridge.session_id}/chromium/send_command_and_get_result"
  response = bridge.http.call(:post, resource, {'cmd':cmd, 'params': params})
  raise response[:value] if response[:status]
  return response[:value]
end

send_cmd(driver, "Network.setBlockedURLs", {'urls': ["*"]})
send_cmd(driver, "Network.enable")

Selenium testing with Ruby, Your guide to running Selenium Webdriver tests with Ruby on BrowserStack. If you need automated web test, WebDriver is the way to go. Selenium WebDriver works using client-server communication. When a Selenium test script is executed, a new session of the browser driver is created, and the browser window is launched. For each command in the test script, a request is sent to the WebDriver API, which is a REST-based

It's not very well documented, but you can also implement request blocking by passing the host-resolver-rules option to chrome and mapping the domain to localhost or an invalid IP. Something like this should work for you:

options = Selenium::WebDriver::Chrome::Options.new
options.add_argument('--host-resolver-rules=MAP www.google-analytics.com 127.0.0.1')
driver = Selenium::WebDriver.for :chrome, options: options

Your PATH is where the system will look for the chromedriver.exe file. If the .exe isn't in your PATH the system won't find it.. You can find details of the file locations on your computer which are included in your PATH by right clicking My Computer and going to Properties -> advanced -> environment variables and find the PATH in the selection box.

I dont know if it can satisfy your requirement as I am no way a network expert, I do use browsermob-proxy extensively to capture network request along with selenium and there is a method to blacklist certain request

  • To block the URI, either launch the browser on a customized proxy or call the DevTool API through Selenium or use a web extension.

  • Thanks! I will look at this now!
  • So looking into this, the DevTools API is the most likely solution we can use. However,I am not seeing examples of how this is being used for what we want to do. I am thinking of calling RequestPattern and using YAML variables as substitutes for the requests I wish to block, but I do not see a call to fail it or ability to return a 404 error, for example. Would you happen to know which calls from this API could accomplish this?
  • it doesn't seem possible to alter the response/status with Selenium/DevTool since it requires to directly listen to the socket to get the events. It looks rather simple with puppeter.
  • Thanks for this. I've spent a day trying to make this work without "Network.enable" call.
  • Awesome. I'll take a look into this as well! Thanks!
