JUnit.org Resources for Test Driven Development

StrutsTestCase is an extension of the standard JUnit TestCase class that provides facilities for testing code based on the Struts framework. StrutsTestCase uses mock servlet objects to actually run the Struts ActionServlet, allowing you to test your Struts code without a running servlet engine. Because StrutsTestCase uses the ActionServlet controller to test your code, you can test not only the implementation of your Action objects, but also your mappings, form beans, and forwards declarations. And since StrutsTestCase does not require a running servlet engine, it's quick and easy to write unit test cases.
