In simple English
When you write code, you write tests to check if it works. This tool measures what part of your code those tests actually check. It runs as part of your normal test commands. It saves results as files in common formats. It costs nothing and runs on your own machine.
What it is
Coverlet is a code coverage framework for modern .NET projects. It instruments compiled code to record which execution paths run during testing.
What it is good for
Solo builders writing C# who need to ensure their tests cover all critical logic before shipping.
- Integrates directly into standard dotnet test commands.
- Supports line, branch, and method coverage metrics.
- Outputs reports in standard formats like Cobertura and JSON.
- Requires .NET 8.0 SDK or newer to run.
- Different drivers have strict incompatibility rules with specific test runners.
- Deterministic builds require manual workarounds to track coverage correctly.
