Selenium – Testing Tool
What is Selenium?
• Selenium is a robust set of tools that supports rapid
development of test automation for web-based
applications.
• Works anywhere JavaScript is supported
• Hooks for many other languages - Java, Ruby,
Python
• Can simulate a user navigating through pages and
then assert for specific marks on the pages
• All you need to really know is HTML to start
using it right away
Selenium
• You can use open source - Selenium tool
• Selenium IDE is a plug-in to Firefox to record and
playback tests (like WinRunner, QTP).
• You can then export the recorded test in most
language e.g. HTML, Java , .NET , Perl , Ruby etc.
• The exported test can be run in any browser and
any platform using "selenium remote control".
Where to get it?
• You can use Selenium-Core and customize
everything – deprecated.
• But it is easier to just get a Firefox plug-in
“Selenium-IDE” that helps you “record” test
Cases.
• You can record how an app is being used and then
playback those recordings followed by asserts.
• Get everything at: www.openqa.org/selenium/
Selenium Components
Selenium-IDE
• Integrated Development Environment for building Selenium test
cases.
• Operates as a Firefox add-on and provides an interface for
developing and running individual test cases or entire test
suites.
• Selenium-IDE has a recording feature, which will keep account
of user actions as they are performed and store them as a
reusable script to play back.
• It also has a context menu (right-click) integrated with the
Firefox browser, which allows the user to pick from a list of
assertions and verifications for the selected location.
• Offers full editing of test cases.
• Although it is a Firefox only add-on, tests created in it can also
be run against other browsers by using Selenium-RC &
specifying the name of the test suite on the command line.
Selenium-RC (Remote Control)
• Selenium-RC provides an API (Application
Programming Interface) and library for each of its
supported languages: HTML, Java, C#, Perl, PHP,
Python, and Ruby.
• This ability to use Selenium-RC with a high-level
programming language to develop test cases also
allows the automated testing to be integrated with a
project’s automated build environment.
Selenium-Grid
Selenium-Grid allows the Selenium-RC solution to scale for
test suites or test suites to be run in multiple environments.
• With Selenium-Grid multiple instances of Selenium-RC are
running on various operating system and browser
configurations, each of these when launching register with a
hub. When tests are sent to the hub they are then redirected
to an available Selenium-RC, which will launch the browser
and run the test.
• This allows for running tests in parallel, with the entire test
suite theoretically taking only as long to run as the longest
individual test.
Steps to start with Selenium!
1) Begin: write and run tests in Firefox.
Selenium IDE is a Firefox add-on that records clicks, typing,
and other actions to make a test, which you can play back in
the browser.
2) Customize: your language, your browser.
Selenium Remote Control (RC) runs your tests in multiple
browsers and platforms. Tweak your tests in your preferred
language.
3) Deploy: scale out, speed up
Selenium Grid extends Selenium RC to distribute your tests
across multiple servers, saving you time by running tests in
parallel.

Tests developed on Firefox via Selenium-IDE can be executed on any other supported
browser via a simple Selenium-RC command line.

Selenium Commands – Selenese
1) Actions are commands that generally manipulate the state of
the application. They do things like “click this link” and “select
that option”.
• Can be called with “AndWait” suffix, e.g. “clickAndWait”.
2) Accessors examine the state of the application and store the
results in variables, e.g. “storeTitle”.
• They are also used to automatically generate Assertions.
3) Assertions are like Accessors, but verify that the state of the
application conforms to what is expected. Eg. “make sure the
page title is X”, “verify that this checkbox is checked”.
• All Selenium Assertions can be used in 3 modes: “assert”,
“verify”, and ” waitFor”. For example, you can “assertText”,
“verifyText” and “waitForText”.

Creating a Test Suite
A Test Suite in Selenium is just an HTML file that contains a
table of links to tests
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
