Enter the total number of lines, functions, and branches in your code, along with how many are covered by tests. The tool will calculate coverage percentages and provide quality insights.
Understanding Test Coverage Metrics
Test coverage is a crucial quality metric that measures how much of your code is tested. Higher coverage generally indicates better code quality and fewer bugs in production.
Coverage Types Explained
- Line Coverage: Percentage of code lines executed during testing
- Function Coverage: Percentage of functions called during testing
- Branch Coverage: Percentage of conditional branches taken during testing
- Overall Coverage: Weighted average of all coverage metrics
Best Practices for Test Coverage
- Aim for at least 80% overall coverage for production applications
- Focus on critical business logic and edge cases
- Use coverage reports to identify untested code paths
- Combine with other quality metrics like code complexity

Frequently Asked Questions
Q. What's considered good test coverage?
Generally, 80%+ is excellent, 60-80% is good, 40-60% is fair, and below 40% needs improvement.
Q. Should I aim for 100% coverage?
While 100% coverage sounds ideal, it's often impractical and may not guarantee bug-free code. Focus on meaningful tests.
Q. How do I improve coverage?
Write tests for uncovered functions, add tests for edge cases, and ensure all code branches are tested.
Q. Is this tool language-specific?
No, this calculator works with coverage data from any programming language or testing framework.
