    What is Selenium?

    • Selenium is a suite of software tools to automate Web Browsers.

    • It is an Open source suite of tools mainly used for Functional and Regression Test Automation.

    • Selenium supports various Operating environments.

    MS Windows


    Macintosh etc...

    • Selenium supports various Browsers.

    Mozilla Firefox


    Google Chrome


    Opera etc...

    Note: Selenium IDE supports Mozilla Firefox only.

    • Selenium supports various programming environments to write programs (Test scripts)






    History of the Selenium Project

    • Selenium first came to life in 2004.

    • In 2006, Selenium WebDriver was launched at Google.

    • In 2008, the whole Selenium team decided to merge Selenium WebDriver with Selenium RC in order to form more powerful tool called Selenium 2.0
    Selenium's Tools Suite

    Selenium IDE

    It is a Firefox browser plug in, used to create and execute Test cases.

    Selenium IDE features:

    • Create Test Cases, Test suites (We can Record test cases or type Test steps using element locators and Selenese commands)

    • Edit Test Cases

    • Execute Test cases, Test suites

    • Debug Test Cases.

    • Enhance Test Cases

    • Export Test cases to other formats (java, ruby etc...)

    Note: selenium IDE Test case default format is .html
    Drawbacks of Selenium IDE

    • It supports Mozilla Firefox browser only.

    • It doesn't support Programming logic/features to enhance Test cases.

    • It doesn't support Data Driven Testing.

    • It is not suitable for complex test case design.

    • No centralized maintenance of Objects/Elements
    Selenium WebDriver

    • It is a Programming interface to create and execute Test cases.
    Selenium IDE has IDE but doesn't have Programming interface

    Selenium WebDriver has Programming interface but doesn't have IDE

    UFT/QTP has both IDE as well as Programming interface
    • Selenium WebDriver supports various programming environments to write programs.

    • Using Element/Object locators/properties and Webdriver Methods we can create and execute Test cases.

    • Selenium Webdriver supports various browsers to create and execute test case/test script/test

    Note: Browser driver varies from one browser to another.

    • Selenium WebDriver supports various operating environments

    Drawback of Selenium WebDriver

    • It doesn't generate detailed Test Reports.

    • No centralized maintenance of Object/elements
    Selenium Grid

    • Selenium Grid is used to execute tests across multiple browsers, operating environments and machines in parallel.

    • Selenium Grid 2 supports Selenium RC Tests as well as Selenium WebDriver Tests.
