First you need to have Selenium RC installed and launched. It's pretty simple. Download it, go to the selenium-server-1.0 and enter in command line
java -jar selenium-server.jar
Your Selenium server is started on the 4444 port, ready to be used ! You also need the selenium-client installed.
sudo gem install selenium-client
Your hard drive is now a bit less empty. We can start having fun with code !
require 'rubygems'
require 'selenium'
# We load Selenium
@selenium = Selenium::SeleniumDriver.new("localhost", 4444, "*firefox", "http://42.dmathieu.com/", 10000);
@selenium.start
# We go to the main page and take the screenshot
@selenium.open "/"
@selenium.capture_entire_page_screenshot(File.expand_path(File.dirname(__FILE__)) + 'screenshot.png', '');
# We unload Selenium
@selenium.stoprequire 'rubygems'
require 'selenium'
Then we load Selenium, indicating the URL we wish to visit and the browser with which we want to visit it.
@selenium = Selenium::SeleniumDriver.new("localhost", 4444, "*firefox", "http://42.dmathieu.com/", 10000);
@selenium.start
We load the page, take the screenshot and save the created image.
@selenium.open "/"
@selenium.capture_entire_page_screenshot(File.expand_path(File.dirname(__FILE__)) + 'screenshot.png', '');
And we don't forget to free the memory.
@selenium.stop
And then the magic happens. Our beautiful screenshot (of the entire page, not only the screen) is then generated.
