Build Laboratory

Started with a Roman Numeral converter codebase to test build tools and I've expanded it to include Advent of Code solutions, where I take my time as write them as best I can.

Contains

• Some code to convert Roman numerals to numbers and back
• Some Unit tests to test the Roman Numeral conversions
• Pitest's dependencies to mutate the code and validate the unit tests
• Reports published to GitHub pages here using peaceiris/actions-gh-pages
  • JaCoCo code coverage
  • Pitest mutation testing
  • Checkstyle reports
• Checkstyle reports attached to commits via jwgmeligmeyling/checkstyle-github-action. Using a branch of this (cmelchior/checkstyle-github-action) to use a newer version (16) of node

Workflow

1. Write the failing test
2. Write the code to pass the test
3. Run Checkstyle (checkstyle:check)
4. Fix style issues
5. Run Mutation Testing (pitest:mutationCoverage)
6. Fix mutation issues

Next Up

• Pitest attached to commits, evaluating Bonajo/pitest-report-action
• Figure out why Pitest sees 100% coverage but Jacoco is much lower (6% at the time of writing)
• GitHub Actions generated badges
