Testing Standards and Coverage Requirements

This rule enforces comprehensive testing practices including unit test isolation, coverage thresholds, test tagging, and quality gates to ensure reliable, maintainable software.

Unit Test Isolation and Coverage

Description

Each business class or function MUST include deterministic unit tests covering at least 80% of its logic branches. The goal is to validate correctness at the unit level, independently from external systems.

Purpose

To catch regressions early, improve maintainability, and ensure every class's logic behaves as expected under varied inputs. This contributes to secure, reliable software that aligns with SDLC testing practices and auditability.
