FoundationDB is peak testing-driven development.
The entire thing is designed to run in a reproducible simulator.
TDD is not my thing I'll admit, I suppose more BDD. I think anytime you refuse to acknowledge the forest regularly during development it becomes a limiting factor, but I guess it heavily depends on the project. A database design has a pretty fixed high level architecture theses days.
