Is it possible to take a screenshot of the whole page with Selenium/Capybara?

In case anyone washed up this shore looking for how to do this with Poltergeist you just need to pass the full argument:

page.save_screenshot('screen.png', full: true) # If providing a custom file name.page.save_screenshot(full: true)               # Capybara sets a name based on timestamp.page.save_and_open_screenshot('screen.png', full: true) # Same as save_screenshot.page.save_and_open_screenshot(full: true)               # Same as save_screenshot.

Docs.

Hope it helps!

Turns out I've been using the take_screenshot method that was provided by the headless gem, when I could have just used the page.save_screenshot() method, which does exactly what I need. Thank you, Andrey.

I tried a lot of things to get full height working with Capybara/Selenium.

Only one thing I tried seemed to work, and it was using headless_chrome. Bear in mind that I use a loop to take screenshots at different widths:

  def screenshot    driver = Capybara.current_session.driver    window = Capybara.current_session.driver.browser.manage.window    widths = [320, 1380] #leave normal w as last    widths.each do |w|      window.resize_to(w, 900)      total_width = driver.execute_script("return document.body.offsetWidth")      total_height = driver.execute_script("return document.body.scrollHeight")      window.resize_to(total_width, total_height)      save_screenshot    end  end

I resize it twice to get the height info.

rails_helper.rb:

Capybara.register_driver :headless_chrome do |app|  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(    chromeOptions: {       "args" => %w{         headless         disable-gpu        --disable-notifications      }     }  )  Capybara::Selenium::Driver.new app,    browser: :chrome,    desired_capabilities: capabilitiesendCapybara.javascript_driver     = :headless_chromeCapybara.current_driver        = :headless_chrome
