Visual Testing with Selenium in Rails

Pre-Request

Image Compare in Ruby

Simple Note





Gemfile

Added gem 'chunky_png'
(so need to run 'bundle install')



test_helper.rb

require two more modules 'fileutils' and 'chunky_png'

Added class ActiveSupport::VisualTestingHelper for visual testing



Added test case 'visual_testing_test.rb'



The screenshots will be stored in folder visualTesting
each test case has its own folder



Almost done the Selenium part, need to build Web App to work with it (e.g., confirm and select new base image via webpage) later.
