http://www.gcreddy.com/2016/01/introduction-to-selenium.html Introduction to Selenium tutorial explains that What is Selenium?, History of the Selenium Project and Selenium's tools suite. Selenium IDE features and Drawbacks, Selenium RC features, Selenium WebDriver features and Drawbacks, Selenium Grid features. Advantages and Disadvantages of Selenium. 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 Linux Macintosh etc... • Selenium supports various Browsers. Mozilla Firefox IE Google Chrome Safari Opera etc... Note: Selenium IDE supports Mozilla Firefox only. • Selenium supports various programming environments to write programs (Test scripts) Java C# Python Perl Ruby PHP ------------------------------------------------ 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. -------------------------------
