RE: ServletUnit with Struts
http://httpunit.sourceforge.net/ I believe that it is primarily a functional testing tool. I would imagine that you could use it for load-testing... I wouldn't believe it. Our attempts to load test with HttpUnit spent more time parsing code on the client than they did generate HTTP requests. -- dIon Gillard, Multitask Consulting Work: http://www.multitask.com.au JavaNews: http://www.multitask.com.au/JavaNews - Forwarded by dIon Gillard/Multitask Consulting/AU on 31/08/2001 02:24 PM - RE: ServletUnit with Struts ServletUnit is part of the open-source HttpUnit testing framework. You can get HttpUnit from SourceForge at: http://httpunit.sourceforge.net/ I believe that it is primarily a functional testing tool. I would imagine that you could use it for load-testing... Regarding my original problem. The solution I am now pursuing, so far with success, is removing almost all of the application-specific meat from my Action subclasses. I will delegate to a simple command class from the action. The command class will take input paramaters, access the model layer to carry out the operation, and make available a logical forwarding name, result objects hash, and ActionErrors which can be accessed by the Action class following command execution. All that will be left in the Action class will be Struts frame-worky stuff. The consequence is that I can unit test the command independently with vanilla junit, without relying on a host of mock servlet / struts objects or an in-container testing framework. The only Struts object I'm going to allow the commands to work with is an ActionErrors instance. Removing that Struts dependency would be even nicer, in that you could then survive a departure from the struts framework with the vast bulk of your control layer logic unaffected. Easy to get rid of the ActionErrors and just have the command class save the keys of the errors in a collection... We'll see how this goes...

+1 = The day I became a true believe in layered Web applications was the
day I realized that the only reasonable way to Unit Test a Web
applications was to separate the business logic from the Web tier, so
tools like JUnit can be used.
Ideally, an Action should be an adapter to handle the error checking and
control flow. Everything else should be delegated to other objects, with
no HTTP dependencies, that can be used in other environments, and tested
with Junit.
The only Struts object I'm going to
allow the commands to work with is an ActionErrors instance. Removing that
Struts dependency would be even nicer, in that you could then survive a

layer logic unaffected. Easy to get rid of the ActionErrors and just have

You might consider having the command class return generic error codes,
and then map those to the ActionErrors. For (quick and dirty) example:
int error = command(something);
if (error==CommandErrors.NOT_FOUND) {
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(errors.not.found));
}

RE: ServletUnit with Struts
Jim: One of our contributors has just recently integrated Cactus with our framework, and Struts components can be tested that way as well, and we've used Junit for some time too. You may find some useful code for what you're doing that way... I know he did a lot of work getting the initialization to come up clean, so it may save you some time, if I understand what you're looking for correctly.
