Coverlet for .NET

Use the open-source free `coverlet` toolchain for .NET code coverage. Use when a repo needs line and branch coverage, collector versus MSBuild driver selection, or CI-safe coverage commands. USE FOR: coverlet setup; CI line or branch coverage; choosing between collector and MSBuild drivers. DO NOT USE FOR: coverage report rendering by itself; repos that intentionally use a different coverage engine. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

Trigger On

  • the repo uses or wants coverlet
  • CI needs line or branch coverage for .NET tests
  • the team needs to choose between coverlet.collector, coverlet.msbuild, or coverlet.console

Workflow

  1. Choose the driver deliberately:

- coverlet.collector for VSTest dotnet test --collect - coverlet.msbuild for MSBuild property-driven runs - coverlet.console for standalone scenarios

  1. Add coverage packages only to test projects.
  2. Do not mix coverlet.collector and coverlet.msbuild in the same test project.
  3. Pair raw coverage collection with ReportGenerator only when humans need rendered reports.

Deliver

  • explicit coverage driver selection
  • reproducible coverage commands for local and CI runs

Validate

  • coverage driver matches the runner model
  • coverage files are stable and consumable by downstream reporting
