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

Answer 1

I found this blog post useful for setting up headless chrome with selenium in ruby

require "selenium-webdriver"

# configure the driver to run in headless mode
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument('--headless')
driver = Selenium::WebDriver.for :chrome, options: options

driver.navigate.to "https://www.google.com"

# resize the window and take a screenshot
driver.manage.window.resize_to(800, 800)
driver.save_screenshot "screenshot.png"
