  Overview History: originatedfrom TW Time Sheet application Extremely popular Open Source Web testing tool Can be used for Acceptance / Functional testing Can be used for reproducing bugs

  Architecture

  Table or driverbased? Table based approach fine for simple tests. No programming required Doesn't scale – duplication is a major issue. Driver approach better for 'Real' test suites Can develop tests in language of choice: C#, Java, Ruby, Python, Perl Easier data management via DB / Excel
• 9.
  Maintaining Test SuitesTest code is just like production code! Needs refactoring, abstraction API for the application Can build tests from API building blocks Try to maintain meaning – in test names, variable names, comments, and suite organization
• 10.
  Evolving Test SuitesDo your test suites break as the app evolves? The importance of DRY: Don't Repeat Yourself Minimize changes to test suite as app changes Avoid redoing / reworking entire test suites Avoiding duplication simpler for test code: test steps execute sequentially Methods, parametrization To some extent, Object Orientation

  Ajax support Seleniumsupports testing Web 2.0 applications Monitor the DOM for completion of Async calls waitForCondition() waitForValue()
• 13.
  Continuous Integration RunSelenium tests as part of the build Works with both Core and Driven modes (Each time a developer checks in, if necessary) Can generate HTML reports, published to entire team Helps catch bugs ASAP Addresses risk of catching bugs late in the cycle

  Limitations Most limitationsvalid if using Selenium Core: Alerts “ Same Origin Policy” File uploads
