Test automation involves using software to set test preconditions, control test execution, compare outcomes to predictions, and report results. Selenium is an open source test automation tool that supports cross-browser testing through scripts in languages like Java and Python. Selenium IDE allows recording and playing back tests in Firefox, while Selenium RC allows running tests on multiple browsers through a server.

- 2. Test Automation Test automation is the use of software To set test preconditions. To control the execution of tests. To compare the actual outcomes to predicted outcomes. To report the Execution Status. Commonly, test automation involves automating a manual process already in place that uses a formalized testing process.

- 4. Selenium Selenium is a robust set of tools that supports rapid development of test automation for web-based applications. Selenium provides a rich set of testing functions specifically geared to the needs of testing of a web application. Selenium operations are highly flexible, allowing many options for locating UI elements and comparing expected test results against actual application behavior.
- 5. Selenium Features Supports Cross Browser Testing. The Selenium tests can be run on multiple browsers. Allows scripting in several languages like Java, C#, PHP and Python. Assertion statements provide an efficient way of comparing expected and actual results. Inbuilt reporting mechanism.

- 7. Selenium IDE Selenium IDE is an integrated development environment for Selenium tests. It is implemented as a Firefox extension, and allows you to record, edit, and replay the test in firefox Selenium IDE allows you to save tests as HTML, Java, Ruby scripts, or any other format It allows you to automatically add assertions to all the pages. Allows you to add selenese commands as and when required
- 8. Selenium IDE Installation Using Firefox, first, download the IDE from the SeleniumHQ downloads page When downloading from Firefox, you’ll be presented with the Window A. (See Next Slide) Select Install Now. The Firefox Add-ons window pops up, first showing a progress bar, and when the download is complete, displays the Window B. (See Next Slide) Restart Firefox. After Firefox reboots you will find the Selenium-IDE listed under the Firefox Tools menu. Selenium Installation Selenium IDE - UI Selenium Options Recoding a Selenium Test Case General Selenium Commands Selenium Script Running Creating a Test Suite Test Runner & Running options Verification Commands
- 9. Selenium WaitFor Commands waitForPageToLoad This command will make the script to wait till the page loads. Syntax is waitForPageToLoad(timeout); Time out is the maximum time the script will wait for the page to load.
- 10. Limitations of Selenium IDE Can run the test only on Firefox No Programming login (like loops, conditional statements) can be applied Selenium IDE can execute scripts created in Selenese only. It is difficult to use Selenium IDE for checking complex test cases involving dynamic contents
- 11. Selenium RC A solution to cross browser testing. A server, written in Java and so available on all the platforms. Acts as a proxy for web requests from them. Client libraries for many popular languages. Bundles Selenium Core and automatically loads into the browser
- 12. Installing Selenium RC Software Required Selenium Test Automation Process How Selenium Works Process of Developing Selenium Java Scripts. Recorded script into Java Eclipse IDE Scrip ViewPackage Explorer console
- 13. Script View
- 14. Some Java Basics Java Data Types Int, float, String, char, Boolean and double Declarations String s = “Selenium”; Int i = 20; float cur = 3.35; Operators * ,/ ,% ,+, - are the mathematical operators * ,/, %, have a higher precedence than + or -
- 15. Relational Operators == Equal (careful) != Not equal >= Greater than or equal <= Less than or equal > Greater than < Less than
- 16. Programming Elements If Condition if (name != “selenium”) { System.out.print(“Tool Changed”); } Else { System.out.print(“Tool is ok”); } Loop n times for ( i = 0; i < n; n++ ) { // this code body will execute n times // I from 0 to n-1 }
- 17. Selenium-Grid Selenium-Grid allows the Selenium-RC solution to scale for test suites or test suites to be run in multiple environments. • With Selenium-Grid multiple instances of Selenium-RC are running on various operating system and browser configurations, each of these when launching register with a hub. When tests are sent to the hub they are then redirected to an available Selenium- RC, which will launch the browser and run the test. • This allows for running tests in parallel, with the entire test suite theoretically taking only as long to run as the longest individual test.
- 18. What's good? Relatively easy to automate web UI tests Record/Replay for regression tests RC allows integration with CI and JUnit/FitNesse tests
