I’ve been exploring TDD + LLMs, and I’m excited to share my thoughts in this new blog post: marabesi.com/2025/06/22/a...
LLMs are offering exciting new possibilities for generating test code, generating data for testing, and even understanding requirements.

Working effectively with legacy code.
From a manual testing, to automated testing using Golden master and characterization testing.
From structural programming to OOP.
From an awkward dependency to dependency inversion.
