Coverlet Coverage for Measuring Test Effectiveness in .NET Applications

Sophie Lane 1 w

Coverlet coverage is a popular code coverage solution used in .NET projects to measure how much of an application’s code is exercised by tests. It integrates seamlessly with common .NET testing frameworks, making it a practical choice for teams that want visibility into test effectiveness without complex setup.

By using coverlet coverage, teams can generate detailed reports showing statement, branch, and line coverage. These insights help identify untested logic, highlight risk areas, and guide improvements in unit and integration tests. Coverlet coverage is often used in CI pipelines to track coverage trends over time and detect drops after code changes.

Another advantage of Coverlet coverage is its flexibility. It can be run locally during development or as part of automated builds, allowing developers to catch gaps early. The tool also supports multiple output formats, making it easy to integrate with reporting and quality dashboards.

When used thoughtfully, Coverlet coverage helps .NET teams strengthen test quality, reduce regression risk, and maintain confidence as applications evolve.
