Want to test your entire Web 2.0 app, from AJAX and DHTML through browser-rendered HTML into a live instance of your application and database? Most web testing frameworks have gaps in their coverage: JUnit and Test::Unit miss the client frontend; JSUnit misses the server backend; web testing frameworks miss some or all of the JavaScript. With Selenium we have a framework that can test the whole application, from browser-executed JavaScript, through a live application backend, then back to assertions on browser-rendered DOM code. Selenium RC takes this further: since you write your tests in your application language, your tests can do data setup and assertions based directly on server-side domain objects that may be inaccessible or only partially accessible from the client side. On our teams we have used and developed a series of helper methods and assertions that allow testing of AJAX and DHTML functions as well. In this tutorial we outline the architecture of Selenium RC and walk through code and examples illustrating how to do full-stack testing against a Ruby on Rails application.
