FREQUENTLY ASKED QUESTIONS
================================================================================

Q: Where do I start if I need to fix the tests?
A: Read: backend/docs/COVERAGE_QUICK_START.md
   It has step-by-step implementation guide with code examples.

Q: How much time will this take?
A: 110 developer hours total (~3 weeks full-time, ~6 weeks part-time)
   - Week 1: Fix critical issues (38 hours)
   - Weeks 2-3: Priority 2 tests (42 hours)
   - Weeks 4-5: Priority 3 tests (30 hours)

Q: What's the most urgent thing to fix?
A: CodeIndex build failure in linker_test.go (1-2 hours to fix)
   Then Journey test failure in handler_test.go (1-2 hours to fix)
   Then begin creating tests for DocIndex (24 hours)

Q: Where are the untested functions listed?
A: TEST_COVERAGE_REPORT.md has a section for each package listing:
   - Specific functions with 0% coverage
   - Number of untested functions
   - Test scenarios needed

Q: Can I see example tests?
A: Yes! COVERAGE_QUICK_START.md includes:
