Unable to hide "Chrome is being controlled by automated software" infobar within Chrome v76

After updating Chrome to version 76, I cannot figure out how to hide the "Chrome is being controlled by automated software..." notification overriding some controls on the page.

The latest stable release of ChromeDriver is indeed 76.0.3809.68. The following code worked with Chrome 75 and ChromeDriver 74.

var options = new ChromeOptions();
options.AddArgument("--test-type");
options.AddArgument("--disable-extensions");
options.AddArguments("disable-infobars");
options.AddArguments("--disable-notifications");
options.AddArguments("enable-automation");
options.AddArguments("--disable-popup-blocking");
options.AddArguments("start-maximized");
var driver = new ChromeDriver(driverLocation, options, ScriptTimeout);

Solution 1:

As of 1 Aug 2019 - You can send the excludeswitch - enable-automation to hide the message. and to disable pop up 'Disable developer mode extensions' set useAutomationExtension=false . Refer for useAutomationExtension

Tested on : Windows 10 Version 76.0.3809.87 (Official Build) (64-bit) ChromeDriver 76.0.3809.68

--enable-automation : Inform users that their browser is being controlled by an automated test Reference

     "goog:chromeOptions": {

        "excludeSwitches": [ "enable-automation" ],
        "useAutomationExtension": false
     }

In C# :

To disable pop up "Disable developer mode extensions" and automation info-bar message .

options.AddExcludedArgument("enable-automation");
options.AddAdditionalCapability("useAutomationExtension", false);

In JAVA :

options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
options.setExperimentalOption("useAutomationExtension", false);

In Python :

options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)

In Protractor :

Add below capabilities in conf.js/conf.ts

capabilities: {
    'browserName': 'chrome',
    "goog:chromeOptions": {
      "excludeSwitches": [ "enable-automation" ],
      "useAutomationExtension": false
   }
  },

Solution 2:

Chromium team earlier introduced the infobar Chrome is being controlled by automated test software to disable Developer mode extension popup within Chrome Browser through this commit.

As per the discussion Flakiness due to Chrome automation infobar (Chrome 57+) with the addition of the infobar to display if a session is being controlled by an automated test within Chrome it was observed that the presence of Chrome automation infobar Chrome is being controlled by automated test software intermitently caused the click() function to fail. During the tests, when the the infobar was removed by passing disable-infobars within chrome_launcher.cc then the above tests runs as expected without any issues. [email protected] confirmed that the culprit was the changelog:

Add an infobar if a session is being controlled by an automated test.

This infobar is only displayed if the browser is launched with the --enable-automation switch. It also disables the developer mode extensions warning bubble.

TEST=launch with and without --enable-automation, and check for presence of automation infobar

It was observed that, during a click the infobar animation occurs and we got flaky results. So Chromium team needed to detect this change somehow and recompute the position. The actual problem was, if a Page.frameResized occured we can invalidate the results of some operations and retry (e.g. get element position) but there were other operations that can modify the page, such as mouse clicks. It's possible that a mouse click (which involves a mousemove, mousedown and a mouseup event) can have a resize event in the middle.

Accordingly, Chromium team released a revision through this commit:

Disable info bar animations during automated testing.

Since then Chrome user, to disable the infobar started using:

• Java:

  options.addArguments("disable-infobars");
  

• Python:

  options.add_argument("disable-infobars")
  

• C#:

  option.AddArguments("disable-infobars");
  

Now in the discussion Chrome is being controlled by automated test software infobar doesn't gets suppressed despite using disable-infobars argument Chromium team member [email protected] clearly mentioned:

As of v 76, the ability to suppress the infobar was moved from command line options to Enterprise Policy settings for Chrome.

The change was already mentioned in the Release Notes and Chrome Enterprise release notes as follows

--disable-infobars is no longer supported

Chrome will no longer support the --disable-infobars flag, which was used to hide pop-up warnings
from Chrome Browser. To support automated testing, kiosks, and automation, the
CommandLineFlagSecurityWarningsEnabled policy was added to allow you to disable some security
warnings.

So, from Chrome v76.x onwards --disable-infobars flag is officially deprecated.

Conclusion

The policy is not an option or a capability that is set when ChromeDriver or Chrome is launched as security policies are typically managed by your corporate IT department. Hence usage of disable-infobars have been deprecated.

A small Hack

The --disable-infobars flag can still removed from Chrome v76.x using these 2(two) ExperimentalOption:

• Excluding the switches for enable-automation
• Setting useAutomationExtension to False

Implementations

Here are the implementations:

• Java:

  ChromeOptions options = new ChromeOptions();
  options.addArguments("start-maximized");
  options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
  options.setExperimentalOption("useAutomationExtension", false);
  WebDriver driver = new ChromeDriver(options);
  driver.get("https://google.com");
  

• Python:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://www.google.co.in')
  

Outro

As per the article CommandLineFlagSecurityWarningsEnabled:

Enable security warnings for command-line flags

Supported on: Google Chrome (Linux, Mac, Windows) since version 76

Description: If disabled, prevents security warnings from appearing when Chrome is launched with some potentially dangerous command-line flags.
             If enabled or unset, security warnings are displayed when some command-line flags are used to launch Chrome.
             On Windows, this policy is only available on instances that are joined to a Microsoft Active Directory domain or Windows 10 Pro or Enterprise instances that are enrolled for device management.

Solution 3:

This will work in C#:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("--incognito");
chromeOptions.AddExcludedArgument("enable-automation");
chromeOptions.AddAdditionalCapability("useAutomationExtension", false);
