No support for performance and
batch testing
Limited scope
Manual creation of logs and repositories
High risk of error

10. Birth of Selenium
Jason Huggins, an engineer at ThoughtWorks, Chicago found the repetitious work of
manual testing strenuous and monotonous
He developed a JavaScript program to automate the testing of a web application
The program was called JavaScriptTestRunner
Initially, the new invention was deployed by the inmates at Thoughtworks. However,
in 2004 it was renamed as Selenium and was made open source

11. How does Selenium help?
Speed of execution Accurate results Lesser investment in human resources
Time and cost effective Early time to market Supports re-testing

32. Selenium RC
The browser works accordingly
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

33. Selenium RC
RC Server
Web browser injected with Selenium core
• 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

34. Selenium RC
RC Server
Web browser injected 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

35. Selenium RC
RC Server
Web browser injected with Selenium core
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

36. Selenium RC
The time taken for execution of commands is longer
This additional setup complicates the architecture
RC consists of an additional server that acts as a middle man
APIs supported by Selenium RC are redundant and confusing
Shortcomings of Selenium RC

Grid

56. Selenium Grid
Grid is exceptionally flexible and is integrated with other suite components for simultaneous
execution
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

57. 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

58. Selenium Grid
The hub picks a node that conforms to the requirements (browser and platform) and
passes the test to that node

59. Selenium Grid
The node runs the browser and executes the selenium commands within it

60. Selenium Grid
Limitations of Grid
Limited scalability
Cannot scale up or down on
demand

61. Selenium Grid
Limitations of Grid
Limited scalability
Cannot scale up or down on
demand
Static
Since the nodes are pre-
configured, making changes is a
challenge

62. Selenium Grid
Limitations of Grid
