If you're looking specifically at DAL-generation tools you'll have a hard time integrating this with TDD. Most dal generation tools I know also generate your business objects and tightly couple them to the DAL making testing difficult.

You can look at OR-mapping tools like nHibernate and maybe Linq to sql that enable "persistance ignorance", you can define your business objects yourself and they have no links to the DAL or any other infrastructure code. This makes testing your business logic seperately from your database much easier. I found it also enables other scenario's like occasionally connected clients far better.
