Open Source Software

Open Source Software (OSS) is computer software with it Source code made available & licensed with an open source license in which the copyright holder provides the rights to study, change & distribute the software to anyone & for any purpose.

Test Automation

Test automation is the use of Special Software to control the execution of tests and the comparison of actual outcomes to predicted outcomes.

FrameworkA framework is an integrated system that sets the rules of automation for a specific product

Generations of Various Framework & Scripting techniques

1st Generation: Linear – Procedural code, possibly generated by tools, such as record & playback scripting.

2nd Generation: Structured – Use control structures, if-else, switch, for, while conditions / statements.

3rd Generation: Data driven – Test script data persist outside the script in DB, spreadsheet, cvs, etc.

4th Generation: Keyword driven – Test script instructions / statements persist in spreadsheet, property files.

5th Generation: Hybrid – two or more of the patterns above are user, its also called as script less automation (less scripting)

What is Selenium

Selenium is an open source testing tool for automating web based applications.

It can automate only web based applications. It works on multiple browsers and multiple operating systems.

Helpful to distribute/scale your test cases across multiple platforms.

Being open source and very strong in nature, demand for this tool is increasing.

Components of Selenium

Selenium IDE Selenium 1 (Remote Control) Selenium 2 (WebDriver) Selenium Grid


Benefits of Selenium

Open source

Works on multiple browsers

Works on multiple Operating Systems

Supports many languages for scripting

Supports to tests Ajax Applications, Flash Applications & Database Testing

Multiple test frameworks are supported (Junit4, TestNg, Data driven, Keyword driven, Hybrid, etc)

Can be used for Functional, Regression & Browser compatibility testing

Selenium IDE (Integrated Development Environment)

The IDE is a record and playback tool with built-in debugger and editor

The IDE is an add-on for Mozilla Firefox only, works only on Firefox.

The IDE automatically creates test scripts in the Selenese HTML table format

The IDE can generate code into a wide variety of languages and test frameworks. Such as HTML Selenese, C#, Java, Perl, PHP, Python, Ruby, Bromine, JUnit, NUnit, RSpec, Test::Unit, TestNG, etc.

Selenium RC


Selenium WebDriver

WebDriver is designed to providing an simpler, more concise programming interface along with addressing some limitations in the Selenium-RC API (Application Program Interface).

Selenium-WebDriver was developed to better support dynamic web pages.

Selenium-WebDriver makes direct calls to the browser using each browser’s native support for automation.

You may, or may not, need the Selenium Server, depending on how you intend to use Selenium-WebDriver.

Selenium Grid• The Grid distributes your tests on multiple machines so that you can

run your tests in parallel– Tests can be ran in parallel for reduced execution time– Test can be ran on various browser and operating system

combinations– Generates a collated report from all test machines

• The Grid can be run on a server farm or in the Cloud– The tests are distributed by the Hub server to multiple Selenium

RC machines– The tests can be ran by various Cloud computing services such

as Amazon EC2, Sauce Labs, BrowserMob, and PushToTest– The Grid is written in Java for portability and is executed from

the command line


Selenium Grid


Selenium Grid - Concept

Selenium Grid can be used to run multiple instances on various operating system and browser configurations.



• The Selenium client libraries can be imported into most popular language IDE’s– Eclipse, NetBeans, Visual Studio .NET, etc.– Reuses existing unit testing frameworks– Integrated into Fitnesse frameworks

• Used by QA test teams for functional, regression, and user acceptance testing (UAT)

• Integration into the build process has made it easy to deploy into Continuous Integration Environments

• Used by Developers for test driven development (TDD) in the Agile and extreme programming (XP) community



• Expanded usage by Developers into other areas– Conversion into production monitoring and load testing– Extended hooks into Flash, Flex, and other popular technologies

• Strong support for AJAX technologies

• Cross platform browser and operating system comparison testing

• Run tests in parallel– Using the Grid tests can be run in parallel across multiple RC

(agent) machines from a single Hub machine– Saves time, and runs faster


Why choose Selenium?• Selenium is FREE!

– No licensing costs, so it can be deployed to as many machines as needed in a lab or for local development

– No maintenance renewal costs

• Use Cloud computing services– If hardware is a limited, then opt to have a remote test lab in the

Cloud as needed– Amazon EC2 (functional, regression testing)– Sauce Labs (functional, regression testing)– BrowserMob (production monitoring, load testing)– PushToTest (production monitoring, functional testing, load testing)
