This document provides an overview and history of the Selenium automated testing tool. It discusses the need for test automation and introduces the various Selenium tools, including Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid. Selenium is an open source tool that allows automated testing of web applications across different browsers. It has increased in popularity as a testing standard due to its support for multiple programming languages and ability to find UI elements.

- 2. NEED OF TEST AUTOMATION The word “automation” is misleading. We cannot automate users. We automate some actions they perform, but users do so much more than that. Output checking can be automated, but testers do so much more than that. Automated output checking is interesting, but tools do so much more than that. Call them tools (not “test automation”).
- 3. • Developed in 2004 by Jason Huggins as a JavaScript library used to automate his manual testing routines • Selenium Core is born whose functionality underlies the Selenium RC (Remote Control) and Selenium IDE tools • The Limitation of having a JavaScript based automation engine and browser security restricted Selenium to specific functionality • Google, who has been a long time user of Selenium, had a developer named Simon Stewart who developed WebDriver. This tool circumvented Selenium’s JavaScript sandbox to allow it to communicate with the Browser and Operating System directly using native methods • In 2008, Selenium and WebDriver merged technologies and intellectual intelligence to provide the best possible test automation framework HISTORY
- 4. • Selenium is a suite of testing automation tools used for Web-Base applications: Selenium IDE, Selenium RC, Selenium WebDriver and Selenium Grid • These tools provide a rich set of testing functions specifically geared to varied testing scenarios of all types of Web applications • The operations provided by these tools are highly flexible and afford many options for comparing UI elements to expected application behavior • Selenium tests can be executed on multiple browser platforms INTRODUCTION
- 5. Increases you marketability Has a lot of Java planks Growing Industry standard Assist with the deployment of defective-free code Open source, web-based testing automation tool and cross-browser compliant Muti-language backend support (Java, Ruby, Python, C#, PHP, ect…) WHY USE/LEARN SELENIUM
- 7. • Selenium IDE • Rapid prototyping tool for building test scripts • Firefox plugin • Can be used by developers with little to no programming experience to write simple tests quickly and gain familiarity with the Selenese commands • Has a recording feature that records a user’s live actions that can be exported in one of many programming languages • Does not provide iteration or conditional statements for test scripts • Can only run tests against FireFox • Developed tests can be run against other browsers, using a simple command-line interface that invokes the Selenium RC server • Can export WebDriver or Remote Control scripts (these scripts should be in PageObject structure) • Allows you the option to select a language for saving and displaying test cases SELENIUM TOOLS
- 8. • Selenium RC aka Selenium 1 • It ‘inject’ JavaScript functions into the browser when the browser is loaded and then uses its JavaScript to drive the AUT within the browser • Mainly supported in maintenance mode • Provides support for several programming languages • Selenium WebDriver • Designed to provide a simpler, more concise programming interface in addition to addressing some limitations in the Selenium-RC API • Developed to better support dynamic web pages where elements of a page may change without the page itself being reloaded • Makes direct calls to the browser using each browser’s native support for automation. • Has the Selenium 1 (aka Selenium RC) underlying technology for flexibility and Portability • Migrating From Selenium RC to Selenium WebDriver • Not tied to any particular test framework, so it can be used equally well in unit testing or from a plain old “main” method. SELENIUM TOOLS
- 9. • Selenium Grid • Scales the Selenium RC solution for large test suites and test that must be run in multiple environments • Tests can be run in parallel with simultaneous execution (different tests on different remote machines) • It allows for running your tests in a distributed test execution environment • Used to run your tests against multiple browsers, multiple versions of browser, and browsers running on different operating systems • It reduces the time it takes for the test suite to complete a test pass SELENIUM TOOLS

Introduction of Web Technologies – HTML, XML, XPath, CSS and DOM X-Path Used for locating nodes in an XML document Elements can be located in regards to absolute terms or a relative position to an element that has a specified id or name attribute Can locate elements via attributes other than id or name Starts with “//” By DOM Can be accessed using Javascript Locator type is “document” By CSS Uses the style binding of selectors to elements in a document as a locating strategy Faster than X-Path and can find the most complicated objects in an intrinsic HTML document Locator type is “css” SELENIUM IDE
