================================================================================
CRITICAL GAPS 🔴
================================================================================

1. SEEDING INFRASTRUCTURE (400+ lines untested logic)
   Problem: Recent normalized seeding (RealtyAsset + Listing) has basic tests
            but lacks edge case coverage
   Impact:  Seeding failures go undetected until production
   Action:  ADD 15 TESTS covering:
            - Property normalization edge cases
            - Photo attachment failures & rollback
            - Locale filtering for unsupported languages
            - Transaction safety & rollback
            - Materialized view refresh failures
   Effort:  4-5 hours
   Files:   spec/libraries/pwb/seeder_spec.rb

2. SERVICES WITHOUT TESTS (3 critical services)
   Problem: EmailTemplateRenderer, MlsConnector, SignupApiService have zero tests
   Impact:  Customer notifications, property imports, provisioning at risk
   Action:  ADD 50 TESTS total:
            - EmailTemplateRenderer: 20 tests (Liquid rendering, HTML→text)
            - MlsConnector: 15 tests (RETS client, query parsing, errors)
            - SignupApiService: 15 tests (API calls, timeouts, responses)
   Effort:  10-12 hours
   Files:   spec/services/pwb/email_template_renderer_spec.rb (new)
            spec/services/pwb/mls_connector_spec.rb (new)
            spec/services/pwb/signup_api_service_spec.rb (new)

3. CONTROLLER CONCERNS - INCOMPLETE INTEGRATION
   Problem: SiteAdminIndexable & LocalizedSerializer have unit tests but lack
            integration tests verifying actual controller behavior
   Impact:  Cross-tenant data leakage, API serialization errors
   Action:  ADD 15 TESTS:
            - SiteAdminIndexable: 10 integration tests for search, isolation
            - LocalizedSerializer: 5 tests with real Mobility objects
   Effort:  3-4 hours
   Files:   spec/controllers/concerns/site_admin_indexable_spec.rb (+10)
            spec/controllers/concerns/localized_serializer_spec.rb (+5)

4. MODELS WITHOUT TEST FILES (9 models, 150+ LOC untested)
   Problem: EmailTemplate, ImportSource, SubscriptionEvent, etc. lack dedicated
            test files (though may be indirectly tested via associations)
   Impact:  Validation logic, associations untested at model level
   Action:  CREATE 9 TEST FILES with 5-10 tests each (45-50 tests total)
   Effort:  4-6 hours
   Files:   spec/models/pwb/email_template_spec.rb (new)
            spec/models/pwb/import_source_spec.rb (new)
            ... etc for each model

5. CROSS-TENANT ISOLATION - LIMITED NEGATIVE TESTS
   Problem: While multi-tenancy is used, explicit "negative tests" that verify
            one tenant CANNOT access another's data are sparse
   Impact:  Security vulnerability: data leakage between websites
   Action:  ADD 10 INTEGRATION TESTS explicitly verifying isolation:
            - Index queries scoped correctly
            - Show/edit endpoints reject cross-tenant access
            - Search results don't leak
            - Associations scoped properly
   Effort:  2-3 hours
   Files:   spec/integration/cross_tenant_isolation_spec.rb (new)

================================================================================
HIGH-PRIORITY RECOMMENDATIONS
================================================================================

PHASE 1 (CRITICAL - 1-2 weeks):
  1. EmailTemplateRenderer tests (20) - customer notifications
  2. Service tests: MlsConnector, SignupApiService (30) - integrations at risk
  3. SiteAdminIndexable isolation tests (10) - potential data leak
  4. Seeding normalization tests (15) - recent feature stability

PHASE 2 (HIGH - 2-3 weeks):
  5. Create 9 untested model test files (45-50 tests)
  6. ListingStateable edge cases (8) - state machine safety
  7. Cross-tenant isolation negative tests (10) - security
  8. LocalizedSerializer real model tests (5) - API correctness

PHASE 3 (MEDIUM - ongoing):
  9. End-to-end integration tests (10)
  10. Import workflow tests (10)
  11. Performance tests for complex queries

================================================================================

  - Controllers: 70%
  - Services: 70% (missing 3 critical)
  - Integration tests: 40%
  - Multi-tenancy isolation: 50%
  - Concerns & mixins: 45%

  - Services: 15 files (12 with tests, 3 without)
  - Controllers: 40+ files (mostly covered)
  - Concerns: 5 files (2 with tests, 3 without)

================================================================================
KEY INSIGHTS
================================================================================

1. RECENT FEATURES NEED TESTS
   The normalized property schema (RealtyAsset + SaleListing/RentalListing)
   is recent and complex. Comprehensive edge case testing is critical before
   relying on this in production.

2. EXTERNAL INTEGRATIONS AT RISK
   3 services handle external APIs/data without test coverage:
   - EmailTemplateRenderer (Liquid rendering)
   - MlsConnector (RETS client)
   - SignupApiService (provisioning)
   These should be tested FIRST as they block critical workflows.

3. MULTI-TENANCY IS ENFORCED BUT NOT DEEPLY TESTED
   30 test files mention tenancy, but explicit "negative tests" verifying
   data isolation are sparse. Recommend adding parameterized tests that
   run scenarios across multiple websites.

4. SEEDING INFRASTRUCTURE IS MATURE BUT INCOMPLETE
   The seeder/seed_runner is well-structured but edge cases around
   transaction rollback, locale filtering, and photo handling lack coverage.

5. CONTROLLER CONCERNS NEED INTEGRATION TESTING
   Unit tests exist but real request-level tests would catch:
   - Cross-tenant query leakage
   - Serialization errors with actual models
   - Search scope issues

================================================================================
HOW TO USE THESE FINDINGS
================================================================================

For Sprint Planning:
  - Critical work: 21-28 hours
  - High priority: 9-13 hours
  - Total: 30-41 hours (~1 week for full team or 2 weeks for 1 developer)

For Code Review:
  - New features should include tests from Phase 1 patterns
  - Services MUST have tests before merging
  - Multi-tenancy changes should include isolation tests

For New Team Members:
  - Read test_coverage_gap_analysis.md for context
  - Read test_implementation_quickstart.md for examples
