Introduction to Selenium Automation
- 1. Introduction to Selenium Automation Presenter: Saurabh Sharma Manu Parashar 12/18/2013 Mindfire Solutions
- 2. Agenda ď What is Automation and its need ď Selenium History and Backgound ď Features of Selenium ď Architecture of Selenium RC ď Difference between RC and WebDriver ď Basics of IDE and type of locators Presenter: Saurabh & Manu, Mindfire Solutions
- 3. Automation ?? When to Automate? When not to Automate Benefits- Automation ToolsQTP Selenium Jmeter LoadRunner SilkTest etc. -Stable Application -Manual Efforts are high -Regression comes frequently -We have plenty of time for testing One Time effort Saves Time Saves Money Better Outputs - Application changes frequently - Testing time is stipulated - Budget does not allow us Presenter: Saurabh & Manu, Mindfire Solutions
- 4. Selenium Selenium is a set of different software tools each with a different approach to supporting test automation. Different tools under Selenium's Tool Suite are: ďŹ ďŹ ďŹ ďŹ Selenium 2 (aka. Selenium Webdriver) Selenium 1 (aka. Selenium RC or Remote Control) Selenium IDE Selenium-Grid Presenter: Saurabh & Manu, Mindfire Solutions
- 5. Selenium History Selenium -> 2004 -> Jason Huggins -> ThoughtWorks A smart bored-to-the-core guy preferred automating the task to avoid redundant manual effort... ...And hence came SELENIUM Created Javascript library, that became Selenium Core Selenium Core --> Selenium RC + Selenium IDE And finally in 2008, Selenium and Webdriver got merged. Presenter: Saurabh & Manu, Mindfire Solutions
- 6. Features of Selenium ďŹ Open Source Tool ďŹ Multiple browsers and Operating Systems ďŹ Multiple languages for scripting ďŹ Record and playback ďŹ Highly Flexible ďŹ Active Forums/support available Presenter: Saurabh & Manu, Mindfire Solutions
- 7. Selenium RC Selenium RC components are: The Selenium Server which launches and kills browsers, interprets and runs the Selenese commands passed from the test program, and acts as an HTTP proxy, intercepting and verifying HTTP messages passed between the browser and the AUT. Client libraries which provide the interface between each programming language and the Selenium RC Server.
- 8. Selenium RC Architecture Same Origin Policy This security restriction is applied by every browser Objective is to ensure that a siteâs content will never be accessible by a script from another site Proxy Injection The first method Selenium used to avoid the The Same Origin Policy was Proxy Injection It then masks the AUT under a fictional URL
- 10. Selenium RC and Webdriver Webdriver support dynamic web pages where elements of a page change without the page itself being reloaded Has well-designed object-oriented API Webdriver makes direct calls to the browser using each browserâs native support for automation whereas RC âinjectedâ javascript functions into the browser when the browser was loaded and then used its javascript to drive the AUT within the browser. Selenium 2 still runs Selenium 1âs Selenium RC interface for backwards compatibility. Presenter: Saurabh & Manu, Mindfire Solutions
- 11. Selenium IDE (Integrated Development Environment) ďŹ Tool you use to develop your Selenium test cases ďŹ Itâs an easy-to-use Firefox plug-in ďŹ IDE has a recording feature, which records user actions as they are performed and then exports them as a reusable script in one of many programming languages that can be later executed. ďŹ It's a prototyping test script tool ďŹ Can be downloaded from seleniumhq.org
