Coverlet is a cross-platform code coverage tool for .NET that instruments bytecode to measure test coverage.
The tool solves the problem of obtaining accurate code coverage metrics across different operating systems and .NET implementations. Coverlet works by instrumenting the bytecode of your application during test execution, allowing it to track which code paths are exercised by your tests. This instrumentation-based approach enables coverage measurement without requiring source code modifications or special compiler support, making it applicable to any .NET project regardless of how it was built.
Developers should choose Coverlet if they need code coverage analysis that works consistently across Windows, Linux, and macOS environments. It suits projects using the .NET testing ecosystem where you want to integrate coverage reporting into your continuous integration pipeline. The tool is particularly valuable for teams that need coverage data without adding complexity to their build process or test infrastructure.
The project maintains steady development activity with regular updates and bug fixes. The maintainers actively respond to issues and pull requests, indicating ongoing engagement with the user community. The codebase receives consistent improvements to coverage accuracy and support for new .NET versions and features. Development focuses on maintaining cross-platform compatibility and ensuring the instrumentation mechanism remains reliable as the .NET platform evolves.
