Overview
Code coverage provides a rough indicator of how well your code is tested. However, high coverage does not guarantee high quality; it only means the code was executed, not that it was correctly verified.
Common Metrics
- Statement Coverage: Percentage of lines of code executed.
- Branch Coverage: Percentage of decision points (if/else) executed.
- Function Coverage: Percentage of functions called.
Best Practices
Aim for a reasonable coverage level (e.g., 80%), but focus more on writing meaningful tests that cover critical business logic and edge cases.
