In this video, Marco covers: ✔️ What code coverage is (branches, functions, statements & lines) ✔️ How to configure collectCoverageFrom properly ✔️ Setting global coverage thresholds (80% and beyond) ✔️ Enforcing 100% coverage for specific files ✔️ Generating and reading HTML coverage reports ✔️ Identifying untested code paths (if/else branches) ✔️ Why 100% coverage does NOT guarantee test quality By the end of this lesson, you’ll know how to confidently measure your test effectiveness and strengthen your test suite the right way. #Jest #CodeCoverage #JavaScriptTesting #UnitTesting #TestAutomation #SoftwareTesting #FrontendTesting #QualityEngineering
