ReportGenerator

What ReportGenerator is

ReportGenerator converts code coverage reports into readable reports in multiple formats and visualizes covered source lines. This command-line tool accepts reports from coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov, and lcov. Its reports show line and branch coverage; method coverage is a PRO feature. A history chart follows coverage over time, and the summary table offers filtering and sorting. Risk hotspot analysis can use cyclomatic complexity, NPath complexity, and CRAP score when available, with configurable warning thresholds. Output formats include HTML, Clover, Cobertura, OpenCover, SonarQube, lcov, TeamCity summary, XML, Markdown, JSON, CSV, and text. The maker states that GitHub Actions and Azure DevOps are supported. ReportGenerator runs on Windows, Linux, and macOS, and the project is open source under the Apache License. The Free plan costs nothing and provides basic features. PRO options are available on lifetime licenses: Individual is $79, paid once, Team is $249, paid once for up to 10 developers, and Enterprise is $599, paid once for unlimited developers.
