A coverage tool instruments the code, runs the tests, and reports which lines never executed — highlighting untested paths. It's useful as a spotlight on blind spots: code with 0% coverage is code no test has ever run. But coverage is easy to game and a poor target on its own — 100% coverage doesn't mean the tests assert anything meaningful, and chasing a number can produce tests that execute code without checking behavior. For AI\u002FSaaS builders the pragmatic use is directional: watch that coverage doesn't drop on critical modules, and use coverage reports to find genuinely untested logic, rather than treating a high percentage as proof of quality. Practical note: enforce a floor on important paths in CI, but judge tests by whether they'd catch a real bug, not by the coverage badge.","Code coverage measures how much of your source code your tests actually execute — useful for finding untested branches, misleading as a quality target.",null,[11,14,17,20],{"slug":12,"name":13},"ci-cd","Continuous Integration \u002F Continuous Deployment (CI\u002FCD)",{"slug":15,"name":16},"end-to-end-testing","End-to-End Testing",{"slug":18,"name":19},"regression-testing","Regression Testing",{"slug":21,"name":22},"unit-test","Unit Test",[24,28,31,35,38,41,44,47,50,51,54,57],{"slug":25,"category":5,"name":26,"updated_at":27},"agent","Agent","2026-08-24T02:46:36+00:00",{"slug":29,"category":5,"name":30,"updated_at":27},"ai-code-assistant","AI Coding Assistant",{"slug":32,"category":5,"name":33,"updated_at":34},"api-gateway","API Gateway","2026-08-24T02:46:37+00:00",{"slug":36,"category":5,"name":37,"updated_at":34},"api-versioning","API Versioning",{"slug":39,"category":5,"name":40,"updated_at":27},"autonomous-agent","Autonomous Agent",{"slug":42,"category":5,"name":43,"updated_at":34},"blue-green-deployment","Blue-Green Deployment",{"slug":45,"category":5,"name":46,"updated_at":34},"canary-deployment","Canary Deployment",{"slug":48,"category":5,"name":49,"updated_at":34},"chaos-engineering","Chaos Engineering",{"slug":12,"category":5,"name":13,"updated_at":27},{"slug":52,"category":5,"name":53,"updated_at":34},"circuit-breaker","Circuit Breaker",{"slug":55,"category":5,"name":56,"updated_at":34},"cli","Command-Line Interface (CLI)",{"slug":58,"category":5,"name":59,"updated_at":34},"cloud-development-environment","Cloud Development Environment (CDE)"]
