Jason Huggins, an engineer at ThoughtWorks,
Chicago found the repetitious work of manual testing
strenuous and monotonous

testing of a web application

14. Advent of Selenium
He developed a JavaScript program to automate the
testing of a web application
The program was called JavaScriptTestRunner

15. Advent of Selenium

Initially, the new invention was deployed by the inmates at
Thoughtworks. However, in 2004 it was renamed as
Selenium and was made open source

27. Selenium suite of tools
Selenium
suite
• Developed by Shinya Kasatani
• Firefox or Chrome extension that can automate the browser
functionality
• Records user interactions on the browser and exports them as a
reusable script
• Selenese commands can be used to modify the test script
generated after recording
• Selenium IDE deploys on Windows, Linux, and MacOS platforms
Selenium Integrated development environment (IDE)

28. Selenium suite of tools

Selenium Integrated development environment (IDE)
• Selenium IDE ceased to exist in August 2017
• A robust version of IDE was released in 2018 by Applitools
• The new IDE deploys a Selenium Side Runner that allows all IDE
tests to run on any browser, in parallel, and on a grid without
needing to write any code.
• Selenium IDE is integrated with other suite components to provide a
robust interface for application testing

Selenium Remote Control (RC)
• Paul Hammant developed Selenium RC
• Selenium RC is a server written in Java
• RC makes provision for writing application tests in various
programming languages like Java, C#, Perl, PHP, Python
etc.
• The RC server accepts commands from the user program
and passes them to the browser as Selenium-Core
JavaScript commands
• The browser behaves accordingly

• Consider a JavaScript program test.js used by google.com.
• The program can access pages within google.com like
google.com/mail, google.com/login

with Selenium core
• However, it cannot access elements of other domains like
yahoo.com
• Local copies of Selenium core and the web browser had to be
installed so that they belonged to the same domain

This is called Same Origin Policy and Selenium RC was introduced
to address this limitation. The server acts as a client configured HTTP
proxy and "tricks" the browser into believing that Selenium Core and
the web application being tested come from the same origin

38. Selenium

Selenium WebDriver
• Simon Stewart developed WebDriver in 2006
• The first cross-platform testing framework
• Programming interface to create and run test cases
• Makes provision to act on web elements
• Does not require a core engine like RC and interacts natively
with the browser applications
• Supports Java, C#, PHP, Python, Perl, Ruby, etc.
• Supports frameworks like TestNG, JUnit, NUnit

Selenium WebDriver does not require an additional RC. It directly interacts
with browser and controls its working

Selenium Grid
• Developed by Patrick Lightbody
• The main objective of Grid is to minimize test execution time
• Grid was designed to distribute commands to different
machines simultaneously
• Selenium Grid allows the parallel execution of tests on
different browsers and different operating systems
• Grid is exceptionally flexible and is integrated with other suite
components for simultaneous execution

41. Selenium suite of tools

Selenium Grid
The Grid consists of a hub connected to several nodes. It
receives the test to be executed along with information about
the operating system and browser to be run on
