Add Chrome Driver to Selenium

Introduction

This article describe how to add chromedriver and run test case to test multiple browsers in Selenium.

Note:
Environment: Ubuntu 14.04, Rails 4.1

Pre-Request

Make sure you have set up Selenium correctly
Rails, minitest and Selenium

Steps:

1. Download and install google chrome

2. Download and extract chromedriver from
http://chromedriver.storage.googleapis.com/index.html

3. Create a softlink to the extract chromedriver

# create soft link
# change /your/home/ as needed
sudo ln -s /your/home/Downloads/chromedriver /usr/bin/chromedriver

4. edit SeleniumTest/test/test_helper.rb
 to declare browser array

# other code
@@browsers = [:firefox, :chrome]
# other code
def self.browsers
    @@browsers
end

5. generate a new test case

# generate test case
bin/rails generate integration_test add_chrome_driver

6. write test case to test firefox and chrome in one method

require "test_helper"

class AddChromeDriverTest < ActionDispatch::IntegrationTest
  def test_sanity
    ActiveSupport::TestCase.browsers.each do |browser|
     driver = Selenium::WebDriver.for browser
     driver.navigate.to "http://google.com"

     element = driver.find_element(:name, 'q')
     element.send_keys "Hello WebDriver!"
     element.submit

     puts driver.title

     sleep 2
     # quit driver, close browser window
     driver.quit
    end
  end
end

7. then run test cases

# run test cases
rake test
