unit-test-running-coverage-analysis

When to Apply This Skill

• A developer asks "what am I missing?" after initial test generation
• A coverage report (coverage.py, Istanbul, JaCoCo) is available and needs interpretation
• Pre-sprint planning requires a gap estimate and effort forecast for a module
• A team wants to know exactly what it takes to reach a coverage target (e.g. 80%)
