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.

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.

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

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

How to automate a test case?
• Document the scenario and execute it manually.Visit Testlink at 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.
