RSpec With Selenium – Running RSpec Automation Scripts On LambdaTest Selenium Grid

LambdaTest provides support with Selenium WebDriver for pacing the execution of your automation test scripts. LambdaTest is a cloud-based, cross browser testing tool, providing a Selenium grid of 2000+ browsers and browser versions running through real operating systems to speed up automation testing of your web-app or website. This topic will help you to automate your website testing using Selenium with RSpec on LambdaTest.

This topic will be focusing on:

Running a sample Selenium with RSpec on LambdaTest Automation.
Setting up environment for testing your locally hosted web pages or website.
Core Capabilities: understanding and configuring them in your Selenium test suite.
Exploring advanced features of LambdaTest.

Prerequisites For Running RSpec With Selenium

First, you would have to install Ruby and gem on your local system. Installing these platforms is a little different in each operating system

For windows, you can download the latest installed here https://rubyinstaller.org/downloads/.
If you are using Linux or Ubuntu OS, you can run a simple apt command like below. You can also refer to this doc to know more about which command suits your OS better.

$ sudo apt-get install ruby-full

1	$ sudo apt-get install ruby-full

If you are using MacOS, you can run a homebrew command like this:

$ brew install ruby

1	$ brew install ruby

To run tests in parallel you will require the parallel_tests gem.
LambdaTest binary file for running tests on your locally hosted web pages.

Installing Selenium Dependencies For RSpec

Once you have ruby and gem setup, you would now have to install Selenium dependencies. Use the below gem command for installing Selenium:

gem install selenium-webdriver

1	gem install selenium-webdriver

Getting Started With RSpec & LambdaTest

Now that we are all set with prerequisites. It is time we look at a sample code, this code will validate if there is any change in the title of Google’s home page. This code is also available on our RSpec GitHub repository for you to clone and play around.

By using this code example, we will first validate your LambdaTest credentials for authentication purpose. Later, the code will select the basic capabilities such as OS, browser, browser version and so on.

//LambdaTest.rb

require_relative  "readConf"
require "json"
require "selenium-webdriver"
require "rspec"
 
describe "Add Product and checkout" do
       
  before(:each) do

    caps = {

  after(:each) do  
    @driver.quit   
  end
   
  it "Select a product and add into cart, Checkout" do 
    itemName = 'Yey, Lets add it to list' 
    #Click on First Checkbox
    @driver.find_element(:name, 'li1').click
    
    #Click on Second Checkbox
    @driver.find_element(:name, 'li2').displayed?
    
    #Enter item name   
    @driver.find_element(:id, 'sampletodotext').send_keys itemName
         
 
    @driver.find_element(:id, 'addbutton').displayed?
    @driver.find_element(:id, 'addbutton').click    
    
    # Verify Item added successfully
    textAddedItem = @driver.find_element(:css, "[class='list-unstyled'] li:nth-child(6) span").text
    expect(textAddedItem).to eq(itemName)
  end   
   
end

//LambdaTest.rb

require_relative "readConf"

require "json"

require "selenium-webdriver"

require "rspec"

describe "Add Product and checkout" do

before(:each) do

config = ReadConfig.new()

lt_user = ENV['LT_USERNAME']

lt_appkey = ENV['LT_APPKEY']

lt_os = ENV['LT_OPERATING_SYSTEM']

lt_browser = ENV['LT_BROWSER']

lt_browser_version = ENV['LT_BROWSER_VERSION']

if(lt_user == "" || lt_user == nil)

lt_user = config.getDetails('LT_USERNAME')

end

if(lt_appkey == "" || lt_appkey == nil)

lt_appkey = config.getDetails('LT_APPKEY')

end

if(lt_browser == "" || lt_browser == nil)

lt_browser = config.getDetails('LT_BROWSER')

end

if(lt_os == "" || lt_os ==nil)

end

if(lt_browser_version == "" || lt_browser_version == nil)

end

end

it "Select a product and add into cart, Checkout" do

# Verify Item added successfully

textAddedItem = @driver.find_element(:css, "[class='list-unstyled'] li:nth-child(6) span").text

expect(textAddedItem).to eq(itemName)

end

Now, lets create config.conf file.

//config.conf

LT_USERNAME=<YOUR USERNAME>
LT_APPKEY=<YOUR ACCESS KEY>
LT_OPERATING_SYSTEM = win10
LT_BROWSER=chrome
LT_BROWSER_VERSION=63.0

//config.conf

LT_USERNAME=<YOUR USERNAME>

LT_APPKEY=<YOUR ACCESS KEY>

LT_OPERATING_SYSTEM = win10

LT_BROWSER=chrome

LT_BROWSER_VERSION=63.0

Now, add readConfig.rb file.

//readConfig.rb

require ('rubygems')
require ('parseconfig')
 
class ReadConfig
    #function to read .conf file
    def getDetails(key)    
        my_config = ParseConfig.new( File.expand_path(File.dirname(__FILE__)) +'/config.conf')
        value = my_config.params[key]
        return value
    end
end

//readConfig.rb

require ('rubygems')

require ('parseconfig')

class ReadConfig

#function to read .conf file

def getDetails(key)

my_config = ParseConfig.new( File.expand_path(File.dirname(__FILE__)) +'/config.conf')

value = my_config.params[key]

return value

end

The Selenium Webdriver test would open a URL, mark the first two items in the list as done, add an item in the list, and return the total number of pending item. Your results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest dashboard. LambdaTest Dashboard will help you view all your text logs, screenshots and video recording for your entire Selenium tests.

Executing The Test

You would need to execute the below command in your terminal/cmd.

gem bundle
bundle install
rspec LambdaTest.rb

gem bundle

bundle install

rspec LambdaTest.rb
