This document provides an overview of test automation using Selenium. It discusses what test automation is, the benefits of automation, and when it should be used. It then describes several automation tools, focusing on the features of Selenium. The core components of Selenium are outlined, including Selenium IDE, Selenium Remote Control, WebDriver, and Grid. Examples of using Selenium IDE to retrieve values from a list box and check for a specific value are also provided.

- 2. Softsmith Infotech 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.
- 3. Softsmith Infotech 3 Why and When To Automate? • Frequent regression testing • Repeated test case Execution is required • User Acceptance Tests • Faster Feedback to the developers • Reduce the Human Effort • Test same application on multiple environments

- 5. Softsmith Infotech 5 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.
- 6. Softsmith Infotech 6 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. Softsmith Infotech 7 Selenium Components • Selenium IDE • Selenium Remote Control • Selenium WebDriver • Selenium Grid
- 8. Softsmith Infotech 8 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

- 10. Softsmith Infotech 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. Softsmith Infotech 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. Softsmith Infotech 12 How Selenium Works
- 13. Softsmith Infotech 13 Client Drivers Enables communication with Selenium Remote Control Server. Functionality of Selenium is exposed via these drivers. Available in Ruby, Python, Java, C-Sharp …and so on. Give access to the rich features and libraries of the language, including their unit testing framework. Makes it possible to develop automated scripts in the same language as product. Which one you should use? Whatever make sense in your context. Most Popular is java and for the training we will use java

- 15. Softsmith Infotech 15 Script View
- 16. Softsmith Infotech 16 Example 1 – Get the values from the list box and check if the value “HTML” is present in it Implementation Steps 1) First get the values from the list box 2) To get the values from the list box or any other HTML element we need to know its Xpath. (use Xpath checker) 3) The values taken from the list box are stored in a variable. 4) Use the indexOf method to find if “HTML” is present in the extracted variable.

- 18. Softsmith Infotech 18 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.
- 20. Best practices • Use Selenium to verify workflow and session • Don't put Selenium tests in your main development build – run them overnight • Have dedicated machines that run tests • DON'T THINK OF THIS AS A REPLACEMENT FOR EXPLORATORY TESTING!!!
