How do I use Selenium Webdriver on headless Chrome?

Question

I\'m learning to use Selenium for basic things like taking a screenshot, scraping, and testing and would like to use it with headless Chrome, which is now stable as of Chrome 59

I've written a blog post about how to do it. Summing up:

1) Make sure you have Chrome version 57+ on Linux, 59+ on macOS or 60+ on Windows;

2) Add/update the gem selenium-webdriver;

3) Make sure you’re using ChromeDriver version 2.30 or higher;

4) Add the following driver to your spec_helper.rb or rails_helper.rb:

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new app, browser: :chrome,
    options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless disable-gpu])
end

Capybara.javascript_driver = :chrome
