Coverage-based test selection catches runtime imports vitest --changed misses.
Strengths
- •Runtime coverage mapping catches dynamic imports static analysis can't see
- •Explain command shows exactly why each test was selected
- •Works across both Jest and Vitest without configuration changes
Weaknesses
- •Requires initial mapping step before first run
- •Narrow audience—only matters for teams with slow test suites
