2026 Test Coverage: From Metric Traps to Semantic-Aware, Risk-Weighted Quality Engines

The article argues traditional line coverage metrics are inadequate for 2026's AI-native and edge systems, proposing three advances: Semantic-Aware Coverage using LLMs to filter ghost paths, Dynamic Weighted Coverage prioritizing high-risk code via architecture, history, and runtime weights, and a Coverage-First paradigm embedding coverage goals into design and CI pipelines.
