How to disable cookies when running Selenium + Headless Chrome in RSpec

Question

Background:

I'm currently writing tests for a Rails project using RSpec + Capybara. We're using Selenium + Headless Chrome to simulate browser interactions.

Problem:

I want to disable browser cookies for a test. We're currently instantiating the web driver this way in our spec/spec_helper.rb


chrome_capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
  chromeOptions: {
    w3c: false,
    args: %w[headless no-sandbox window-size=1280,2000 no-proxy-server disable-gpu disable-dev-shm-usage],
  },
  loggingPrefs:{browser: 'ALL'},
)

Capybara.register_driver :headless_chrome do |app|
  Capybara::Selenium::Driver.new(app, 
    browser: :chrome, 
    desired_capabilities: chrome_capabilities
  )
end

I've seen many Java examples that disable cookies by passing this setting when instantiating Headless Chrome: "profile.default_content_setting_values.cookies" => 2

However, I haven't been able to get to this to work.

Does anyone know the correct way to instantiate the Headless Chrome instance so that cookies are disabled?

It depends on your chromedriver version. In release 2.31 developers changed:

Feature request: change chromeOptions to goog:chromeOptions

So for now it would look like:

  caps = Selenium::WebDriver::Remote::Capabilities.chrome(
    'goog:chromeOptions' => {
      'args' => [
        '--lang=en',
        '--no-default-browser-check',
        '--start-maximized',
        '--no-sandbox'
      ],
      'prefs' => { 
          "profile.default_content_settings.cookies" => 2 } 
        }
      }
    }
  )

Give it a try!
