SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps you measure and interpret code coverage for .NET projects to ensure testing quality.

Core Features & Use Cases

  • Integrates with Coverlet to collect coverage data during tests.
  • Generates and analyzes coverage reports (line, branch, method) and highlights risk areas.
  • CI/CD ready: provides guidance for automating coverage checks and reporting across Windows and Linux.

Quick Start

  • Run tests with coverage: dotnet test --collect:"XPlat Code Coverage"
  • Generate HTML report: dotnet tool install -g dotnet-reportgenerator-globaltool
  • reportgenerator -reports:"**/coverage.cobertura.xml" -targetdir: coverage -reporttypes:Html
  • Open the report at coverage/index.html

Frequently Asked Questions about dotnet-testing-code-coverage-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I measure .NET code coverage for unit and integration tests?▼

You can measure .NET code coverage by running tests with the built-in XPlat Code Coverage collector using dotnet test, which generates a coverage.cobertura.xml file for unit and integration test analysis.

How do I generate an HTML code coverage report from Coverlet output in .NET?▼

Install the dotnet-reportgenerator-globaltool and run reportgenerator against the coverage.cobertura.xml file to produce a detailed HTML coverage report for local development analysis.

What is the difference between line, branch, and method coverage in .NET testing?▼

Line, branch, and method coverage are metrics interpreted from Coverlet data to highlight risk areas in .NET solutions, showing how thoroughly tests execute individual statements, execution paths, and entire functions.

Can I automate .NET code coverage checks in a CI/CD pipeline across Windows and Linux?▼

Yes, you can integrate Coverlet and ReportGenerator into CI/CD pipelines across Windows and Linux to automate coverage data collection, generate reports, and enforce testing quality gates.

What's the best way to interpret code coverage data to guide test improvements?▼

Interpreting code coverage data involves analyzing line, branch, and method metrics from the ReportGenerator output to identify untested risk areas and guide specific test improvements in .NET solutions.
