ADR-006: All functionality must be tested with pytest

Category: development Provenance: guided-ai

Decision

Every feature, handler, and reconciliation logic must have pytest test coverage. No untested code in production.

Rationale

Quality assurance: Tests catch regressions and validate behavior. pytest ecosystem: Rich plugin ecosystem (pytest-asyncio, pytest-kubernetes, coverage). AI-friendly: Test-driven development works well with LLM assistance. Refactoring confidence: Comprehensive tests enable safe code changes.

Agent Instructions

When implementing features, write tests first or alongside implementation. Unit tests required for all reconcilers and utility functions. Integration tests required for all CRD operations. Refuse to merge code without tests. Run 'make test-pre-commit' before committing.
