The MailReader application for Action 1.3 is a fair example of how to approach unit testing in a web application environment. * http://svn.apache.org/dist/struts/apps/v1.3.0/ Note that this is only a test-build, not a stable release. The MailReader application uses a set of Plain Old Java Objects (POJOs) to represent the business logic. These have their own tests, and, in fact, live in a separate distribution that can be shared by multiple appications. * http://svn.apache.org/viewcvs.cgi/struts/apps/trunk/mailreader-dao/ (Right now, the MailReader business logic isn't available as a separate distribution. To get the source, you'd have to check it out of Subversion: http://struts.apache.org/downloads.html#Source_Code ). This is the key: Strongly separate your business logic so that it is clearly a separate project. Look at the web pages as a client for your business logic. Then look at the unit tests as *another* client. Design the pages, to determine the use cases, then write the business logic, test the logic in isolation (using JUnit), and then call the business logic from your web applications. All the Actions should do is gather input for your business classes, call the business classes, and analyze the result (success or failure). As you plug the business logic into Actions, you can can use tools lioke WebCanoo to test the page flow. * http://webtest.canoo.com/webtest/manual/WebTestHome.html There's also an example of doing that in the MailReader application. Not for nothing, the book JUnit in Action starts out from square one, and goes on to discuss testing some of the hairier aspects of web development, including tag libraries. * http://www.amazon.com/exec/obidos/tg/detail/-/1930110995/apachesoftwar-20/ I worked on this book with Vincent Masool, but it's really his book. And, I'm happy to say, #69 on the JavaLobby Reader Choice list. * http://www.javalobby.org/articles/5books/full.jsp In the free zone, there are several online articles on the topic of unit testing Struts applications. Here are a few links cribbed from Struts Central. * http://www.onjava.com/pub/a/onjava/2005/10/26/test-driven-development-using-strutstestcase.html * http://www-128.ibm.com/developerworks/java/library/j-stc/ * http://www.onjava.com/pub/a/onjava/2004/09/22/test-struts.html * http://www.javaworld.com/javaworld/jw-08-2004/jw-0830-testing.html * http://www.devx.com/Java/Article/20198 * http://www.devx.com/Java/Article/17908/0 * http://javaboutique.internet.com/tutorials/StrutsTestCase/ -- HTH, Ted. ** http://husted.com/ted/blog/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
