* feat: implement property-based testing with gopter
Add comprehensive property-based testing infrastructure to verify
mathematical properties and invariants of critical code paths.
**Property Tests Added:**
- String manipulation properties (normalization, cleaning, formatting)
- Permission merging properties (idempotency, YAML precedence)
- Uses statement formatting properties (structure, @ symbol presence)
- URL parsing properties (org/repo extraction, empty input handling)
**Mutation Tests Created:**
- Permission parsing mutation resistance tests
- Version validation mutation resistance tests
- String/URL parsing mutation resistance tests
Note: Mutation tests currently disabled due to go-mutesting
compatibility issues with Go 1.25+. Test code is complete
and ready for execution when tool compatibility is resolved.
**Infrastructure Updates:**
- Add gopter dependency for property-based testing
- Create Makefile targets for property tests
- Update CI workflow to run property tests
- Add test-quick target for rapid iteration
- Update CLAUDE.md with advanced testing documentation
**Test Results:**
- All unit tests passing (411 test cases across 12 packages)
- All property tests passing (5 test suites, 100+ random inputs each)
- Test coverage: 73.9% overall (above 72% threshold)
* fix: improve version cleaning property test to verify trimming
Address code review feedback: The 'non-v content is preserved' property
test now properly verifies that CleanVersionString itself trims whitespace,
rather than pre-trimming the input before testing.
Changes:
- Pass raw content directly to CleanVersionString (not pre-trimmed)
- Assert result == strings.TrimSpace(content) to verify trimming behavior
- Update generator to produce strings with various whitespace patterns:
- Plain strings
- Leading spaces
- Trailing spaces
- Both leading and trailing spaces
- Tabs and newlines
This ensures the property actually exercises untrimmed inputs and verifies
CleanVersionString's trimming behavior correctly.
* refactor: move inline YAML/JSON to fixtures for better test maintainability
- Created 9 new fixture files in testdata/yaml-fixtures/:
- 4 config fixtures (configs/)
- 3 error scenario fixtures (error-scenarios/)
- 2 JSON fixtures (json-fixtures/)
- Replaced 10 inline YAML/JSON instances across 3 test files

Documentation fixes:
- Corrected CLAUDE.md coverage threshold from 80% to 72% to match Makefile
- Updated mutation test docs to specify Go 1.22/1.23 compatibility
- Enhanced Makefile help text for mutation tests
Benefits:
- Eliminates code duplication and improves test readability
- Centralizes test data for easier maintenance and reuse
- Follows CLAUDE.md anti-pattern guidance for inline test data
- All tests passing with no regressions
* refactor: reduce test code duplication with reusable helper functions
Created targeted helper functions to consolidate repeated test patterns:
- SetupTestEnvironment for temp dir + env var setup (3 uses)
- NewTestDetector for wizard detector initialization (4 uses)
- WriteConfigFixture for config fixture writes (4 uses)
- AssertSourceEnabled/Disabled for source validation (future use)
- AssertConfigFields for field assertions (future use)
Changes reduce duplication by ~40-50 lines while improving test readability.
All 510+ tests passing with no behavioral changes.
