Untested / Partially Tested Files Audit

Untested / Partially Tested Files Audit

Date: 2026-04-01

Priority findings (config-focused)

• _config_dev.yml — no spec coverage found for dev-only settings (incremental, livereload).
• _config_test.yml — no spec coverage found for test config overrides (destination, test url, baseurl, incremental).
• _config.yml — partially covered, but not fully tested end-to-end.
  • Existing tests validate many keys and some contracts.
  • Gaps include full exclude list assertions, source/destination assertions, full author block assertions, and full defaults coverage (especially the assets/css entry).

Additional high-confidence not-fully-tested files

• _layouts/default.html — has a spec, but no exhaustive template regression coverage.
• _includes/nav.html — no dedicated spec found.
• _includes/bugsink.html — no dedicated spec found.
• _scripts/check_required_frontmatter.rb — no dedicated unit spec found.
• _scripts/update_last_updated.rb — no dedicated unit spec found.
• _scripts/external_link_checker.rb — no dedicated unit spec found.

Notes

This is based on a quick mapping of source files to existing spec/**/* coverage and direct checks for config-related specs.
