I've started to think about what it would be like to develop the view part of a 
webapp using the Ajax concepts.
This is because you can't know whether your refactorings will break something 
without tests.
I just wanted to argue that TDD does not slow you down.
This action is now a PicoComponent, honouring constructor based dependency 
injection. And tons of code too. But claiming that I have written a book about 
Excel VBA is just plain hilarious.
But it's better than having to maintain a CheeseAction and a MockCheeseAction.
Gavin and Hibernate rock.
I'm sure you have read all the fuss about it already.
I just wanted to argue that TDD does not slow you down. How do you know whether 
that is needed or even if it's going to work?
More often than anything else it's not even about programming.
After all, the overridden saveCheese method in the "mock" calls the superclass' 
method, right? The result of this is overly complicated tests, in addition to a 
false perception of what is being tested. Post-testing and post-mocking is 
actually quite evil.
NanoContainer is also an interesting sister project that adds scripted 
configuration using a multitude of script languages, as well as integration with 
WebWork, Hibernate and much more.
This involved some simple reflection logic and was implemented in a couple of 
classes.
It tends to open up and cripple the classes even more than they were before.
Seeing this will make it harder to ignore problems related to build time.

I just wanted to argue that TDD does not slow you down. saveCheese method will 
hit the database. Paul and I started it right after I moved to London to start 
working for ThoughtWorks. Its class is generally an implementation of an 
interface or a subclass of some class, either generated dynamically or 
statically coded.
