How to use Fixtures to create sample test data Discussion

Chris, thanks for all the great videos. These are super informative.

I have a question about fixtures and TDD in general.

Should I be creating a fixture for every potential variation in my model? If I've got a list of services associated with clients and statuses (active/inactive) for both the client and services, do I need to be creating fixtures for each possible variation of service type/service status/client status? How do you know when you're over engineering tests?

Thanks in advance.
