Page 4 Selenium Selenium is a free software testing framework for web applications. Selenium Remote Control - – Allows to write tests in any programming language that can make HTTP requests; using any mainstream JavaScript- enabled browser. – Consists of: A server which automatically launches and kills browsers, and acts as a HTTP proxy for web requests from them. Client libraries for Python, Ruby,.NET, Perl, Java, and PHP. – Includes Selenium Core (the test execution framework) as its engine and automatically loads it into the browser.

Page 5 Benefits The testing suites can be executed daily, to check the most recent changes. It takes less time than a manual execution. Spot errors that a human might not notice. Prevent regressions. Free staff to do other non-repetitive tasks and to look for errors that a machine can't spot.

Page 6 Other used tools Selenium IDE: a Firefox extension that allows to record, edit, debug and play back tests. Firebug: a Firefox extension that lets you inspect the HTML file of a web page on an easy way. With it you can also edit and debug the code of a page. Xpath Checker: a Firefox extension that shows the XPath of an element on a web page. In addition, you can write your own XPath expressions and see the elements that match. Ant: a software tool for automating software build processes. JUnit: a unit testing framework for the Java programming language. Eclipse: Java/JUnit development environment

Page 9 What to automate? Drivers and restrictions – Automation is a time consuming task. – Maintainability is an issue. – Only very stable flows should be automated. – Automated test cases have sense if executed at least ten times. – Only user-visible actions are performed – Javascript events could be missed by Selenium. Our pick – The Acceptance test

Page 15 How to automate a test case? Document the scenario and execute it manually. Visit Testlink at Understand the design. Read the documentation and implementation of the main classes. Look for code that you can reuse. Code missing screen definitions. Write the test controller. Test your test.
