cuprite VS ferrum

- add support to Apparition and Cuprite

At some point I'd replace selenium with https://github.com/rubycdp/cuprite for speed.

You might want to give https://github.com/rubycdp/cuprite a try, in case you are currently using the Rails default selenium-webdriver as driver for javascript tests. It's not going through selenium, but controlling a Chrome or Chromium instance in a more direct way. I've recently switched a larger test suite to it, and besides a remarkable speed improvement (I think it was around 20%), most of the previous flakyness was gone.

As recommended on: "Migrating Selenium system tests to Cuprite" https://dev.to/nejremeslnici/migrating-selenium-system-tests-to-cuprite-42ah

It is called Cuprite

What are you using for automation? There's a relatively new gem that I heard good things of, vessel: https://github.com/rubycdp/vessel . It uses ferrum under the hood, a set of Ruby bindings to Chrome/Chromium (https://github.com/rubycdp/ferrum).

I've used https://github.com/rubycdp/ferrum as driver for automated testing with capybara for which it works great. It recommends https://github.com/rubycdp/vessel as higher level abstraction for web scraping.

require "Rubygems" require "Ferrum" def generate_card(browser, card, png, options={}) browser.go_to("http://localhost:4000/cards/#{card}") # see all the options here https://github.com/rubycdp/ferrum#screenshots browser.screenshot(path: "./images/cards/#{png}", full: true, # final image size is window_size x scale scale: 2) end browser = Ferrum::Browser.new(window_size: [800, 418]) # Check what cards we need to make Dir.glob("_posts/*").each do |post| post = File.basename(post, ".md") png = post + ".png" card = post + ".html" generate_card(browser, card, png) unless File.exists?("./images/cards/#{png}") end

That is why we were happy to find out that a new ruby testing driver approach is being developed. It is called Cuprite, it runs the Ferrum library under the hood which, in turn, is an API that directly instruments the Chrome browser using the Chrome DevTools Protocol (CDP). About a week ago, we finally made a serious attempt to make our system test suite run on Cuprite, with especially two questions in our minds:

I've used Ferrum for a couple small scripts in the past before.
