Increase test coverage from 79% to 95%

[genro]

Current Status

Test coverage has been significantly improved from 55% to 79% (+24 points).

Modules at 90%+ Coverage ✅

• config.py: 100%
• processor.py: 100%
• metadata.py: 96%
• server.py: 91%
• include.py: 90%

Remaining Work

cli.py: 55% coverage ⚠️

The main blocker is ~100 lines of interactive CLI code using input() which are difficult to test:

• Lines 189-236: Interactive refresh mode
• Lines 307-358: Interactive apikey management
• Lines 415-520: Interactive serve command setup

These sections prompt the user for input and are hard to test without complex mocking or integration tests.

Possible Approaches

1. Refactor interactive sections to separate I/O from logic (recommended)

   • Extract input/output to dedicated functions
   • Test business logic separately

2. Mock input() and print() in tests

   • Complex to maintain
   • Fragile tests

3. Add integration tests with simulated input

   • More realistic but slower
   • Requires test infrastructure

4. Accept current coverage as sufficient

   • Core logic well tested (90%+ on 5/6 modules)
   • Interactive sections are simple and unlikely to break

Recommendation

Refactor interactive sections when modifying CLI, gradually improving coverage. Current 79% coverage is acceptable for core functionality.
