Rails, minitest and Selenium

Introduction

Assume we will follow TDD (huh?) so build testing environment first.

This article describe how to setup and run selenium with minitest in Rails 4.

Pre-request

Make sure you have installed Rails 4, see
Install Rails 4 in Ubuntu 14.04

Steps

Open Terminal (Ctrl + Alt + T)

execute

# create testing project
rails new SeleniumTest
# go into project folder
cd SeleniumTest

Then edit SeleniumTest/Gemfile, append

gem 'selenium-webdriver'
gem 'minitest-rails'

save Gemfile, go back to terminal and run

# install for selenium-webdriver and minitest-raills
bin/bundle install
# create first test case
bin/rails generate integration_test check_selenium_work

edit generated test case
test/integration/check_selenium_work_test.rb
as below

require "test_helper"
require "selenium-webdriver"

class CheckSeleniumWorkTest < ActionDispatch::IntegrationTest
  def test_sanity
    driver = Selenium::WebDriver.for :firefox
    driver.navigate.to "http://google.com"

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

    puts driver.title

    # do not quit driver so we can see search result
    # driver.quit
  end
end

save test case, then run

rake test

in terminal,

you should see firefox navigate to google and
search "Hello WebDriver!"
