Coverage thresholds prevent code quality from degrading over time by failing builds when test coverage drops below safe levels.
Review this project's test coverage configuration to ensure minimum thresholds are set and enforced in CI/CD.
Configure coverage thresholds in Jest, Vitest, or your testing framework, and add coverage checks to CI/CD.
Explain how to set up test coverage thresholds and what coverage levels are appropriate for different types of code.
Review tests, CI workflows, and enforcement points related to Maintain test coverage thresholds. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.
For full implementation details, code examples, and framework-specific guidance, see references/rule.md.
