You’ll learn what code coverage really means, how to configure coverage thresholds, generate HTML reports, and enforce 100% coverage for critical files, all step by step.
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.
