The core problem is that when the same AI writes both code and tests, both share identical blind spots — tests verify what the code does, not what it should do. A six-layer testing strategy is proposed: static analysis on every save, human-written test expectations before AI implementation, AI-generated tests as supplemental coverage, adversarial review using a fresh AI context, integration/E2E tests, and production monitoring segmented by code origin. Test-first development is framed as the minimum viable workflow for AI-assisted coding, with testing investment scaled to risk level (green/yellow/red zones). The Amazon March 2026 outages are cited as a real-world example of AI code failures at scale. ## Full article daily.dev links to this article rather than hosting it.
