Capybara Selenium Headless Chrome config for CI/CD


Default Capybara Selenium headless Chrome has high chance of not working properly on CI/CD. The following config works on Bitbucket Pipelines

Capybara.register_driver :custom_chrome_headless do |app|
  client = Selenium::WebDriver::Remote::Http::Default.new
  client.read_timeout = 120

  Capybara::Selenium::Driver.load_selenium
  browser_options = ::Selenium::WebDriver::Chrome::Options.new.tap do |opts|
    opts.args << '--headless'
    opts.args << '--disable-gpu'
    # Workaround https://bugs.chromium.org/p/chromedriver/issues/detail?id=2650&q=load&sort=-id&colspec=ID%20Status%20Pri%20Owner%20Summary
    opts.args << '--disable-site-isolation-trials'
    opts.args << '--no-sandbox'
    opts.args << '--disable-dev-shm-usage'
    # opts.args << '--disable-setuid-sandbox'
    opts.args << 'window-size=1200,1100'
  end
  Capybara::Selenium::Driver.new(app, browser: :chrome, options: browser_options, http_client: client)
end

Capybara.default_driver = :custom_chrome_headless
