4. Page 4 Selenium Selenium is a free software testing framework for web applications. Selenium Remote Control - http://seleniumhq.org/projects/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.

5. 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.

6. 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

9. 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 http://wiki.openbravo.com/wiki/Acceptance_Testing http://wiki.openbravo.com/wiki/Acceptance_Testing

15. Page 15 How to automate a test case? Document the scenario and execute it manually. Visit Testlink at http://tools.openbravo.com:8891/testlink/ http://tools.openbravo.com:8891/testlink/ 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.
