ReportGenerator for .NET
Use the open-source free `ReportGenerator` tool for turning .NET coverage outputs into HTML, Markdown, Cobertura, badges, and merged reports. Use when raw coverage files are not readable enough for CI or human review.
Trigger On
- the repo uses or wants
ReportGenerator - CI needs human-readable coverage reports
- multiple coverage files must be merged
Workflow
- Keep collection and rendering separate: Coverlet collects, ReportGenerator renders.
- Prefer the local or manifest-based .NET tool for reproducible CI runs.
- Choose output formats deliberately:
- HtmlSummary - Cobertura - MarkdownSummaryGithub - badges
- Merge multiple reports only when the repo really needs a consolidated view.
Deliver
- readable coverage artifacts for humans and CI systems
- explicit report-generation commands
Validate
- report inputs match the generated coverage format
- generated reports land in a stable artifact path
