From TDD to AIDD: AI-Informed Development Where Tests Co-Evolve with Implementation

The article traces the evolution from Test-Driven Development (TDD) to AI-Informed Development (AIDD), a new paradigm that integrates AI capabilities into every stage of the development lifecycle. It reviews TDD's core 'Red, Green, Refactor' cycle and its benefits, then introduces AIDD as an approach where AI augments developers by enhancing test generation, refinement, and validation. AIDD aims to enable tests and implementation to co-evolve more efficiently, leading to higher-quality software.
