Scenario-Driven Testing for AI Code Generation
Core Principle
The Iron Law: "NO FEATURE IS VALIDATED UNTIL A SCENARIO PASSES WITH REAL DEPENDENCIES"
Mocks create false confidence. Only scenarios exercising real systems validate that code works.
The Truth Hierarchy
- Scenario tests (real system, real data) = truth
- Unit tests (isolated) = human comfort only
- Mocks = lies hiding bugs
As stated in the principle: "A test that uses mocks is not testing your system. It's testing your assumptions about how dependencies behave."
When to Use This Skill
- Validating new functionality
