Not just TDD. Amazon, for instance, is heading towards something between TDD and lightweight formal methods.

They are embracing property-based specifications and testing à la Haskell's QuickCheck: https://kiro.dev

Then, already in formal methods territory, refinement types (e.g. Dafny, Liquid Haskell) are great and less complex than dependent types (e.g. Lean, Agda).
