This looks like a good approach.  I wonder if we can put some fo this logic outside of base.py.  That file is kind of growing out of control.

As we discussed on IRC on Monday, I think it makes sense to move all of the logic for mapping tests to the filesystem out of base into some sort of 'finder' or 'database' class. I decided to not do that until after I had these patches reviewed, just to avoid confusing things, though.

My current vision for base.py (and the port classes generally) is that they should be composite objects that either assemble the desired behavior from other components (like the http server and the test dabase, above) or just declare preferences (worker_model, default_child_processes, etc.)

That sounds like a good plan.  I'll read the patch again now.

Thanks!

Can we move this declaration to the top-level?  It seems like folks should just call the constructor rather than calling the virtual_suite method.

Should we make this function @memoized?

I actually thought having a member function that constructed the object provided better encapsulation and saved subclasses from having to import another symbol, but I don't feel strongly about it, so I will move this to file scope.

I'm not as big a fan of using @memoized on functions that don't take any arguments, but I can add it.
