Roadmap

This page outlines planned features and improvements for Mutagoph.

Completed

• Caching (test results, coverage data, AST parsing)
• Config file support (.mutagoph.yml)
• Inline code annotations (// mutagoph:ignore)
• Progress bar with ETA
• Configurable per-package quality gate thresholds
• Environment variables support (MUTAGOPH_*)
• Full diff of mutations in output (terminal and HTML)
• Coverage-based filtering (--coverage-filter)
• Manual CI workflow dispatch for targeted scans

High Priority (Post-v1)

• Incremental/in-memory compilation
• Performance optimizations (see ISSUES.md in Obsidian vault)
  • Cache test file hashes per directory
  • Parallel coverage gathering
  • LRU cache eviction

Medium Priority

• Suggested test cases for surviving mutants
• XML output (JUnit-style)
• SARIF output
• Configurable verbosity levels

Future / Long-term

• Distributed mutation testing
• Historical trend tracking
• AI integration for test suggestions
• Multi-language support (language-agnostic core)
• IDE integrations (VS Code, GoLand, LSP)
• Real-time feedback (IDE integration)
• SonarQube integration
• Codecov integration
• GitLab CI, Jenkins, CircleCI support
