Code generation isn't necessarily bad, but the point of the exercise it to explore what code will be generated. You don't necessarily have to test *everything*, but the point of the exercise is to explore how you would test *anything*.

So then you must have forgotten one of the following:
* no IDE allowed
* includes 60 mins for lunch
Otherwise I think this can be done in about 10mins.

Anyhow: Looking forward to a more detailed definition of kata.

Objective: To test drive a new Java web application that updates and queries a database.

Acceptance test: A WebDriver test that accesses the application to insert a “Person” object in the application and then searches for the same person.

I start by writing this test, which gives an outside-in approach. However, that means that the test will not pass before I've written and got to pass a number of lower-level tests.
