Priority: High
Impact: Request routing reliability, provider failover
Component: Infrastructure routing
Size: 426 lines, 0% test coverage

Problem

src/infrastructure/models/router.py handles critical provider routing logic but has no test coverage. This manages:

  • Provider selection algorithms
  • Load balancing logic
  • Failover mechanisms
  • Route optimization

Untested routing = production failures.

Files

  • src/infrastructure/models/router.py (426 lines, untested)

Acceptance Criteria

  • Unit tests for routing algorithm correctness
  • Failover scenario testing
  • Load balancing verification
  • Edge cases: no providers, all providers down
  • Performance tests for route selection speed
  • Target: >85% coverage

Focus Areas

  • Provider selection under different load conditions
  • Graceful degradation when providers fail
  • Route caching and invalidation
  • Metrics collection during routing decisions

Critical for system reliability.

Implementation Instructions for Kimi

Target: Add comprehensive tests for src/infrastructure/models/router.py (426 lines, 0% coverage)

Files to Create:

  • tests/infrastructure/models/test_router.py (new file)

Test Structure Focus:

class TestProviderRouter:
    def test_select_provider_round_robin(self):
        # Test round-robin provider selection
        
    def test_select_provider_load_balanced(self):
        # Test load-based provider selection
        
    def test_failover_to_backup_provider(self):
        # Test failover when primary provider fails
        
    def test_no_providers_available(self):  
        # Test behavior with empty provider list
        
    def test_route_caching(self):
        # Test route caching and invalidation
        
    def test_metrics_collection(self):
        # Test routing metrics are collected properly

Key Test Areas:

  1. Provider Selection: Round-robin, load-balancing, priority-based
  2. Failover Logic: Provider failures, graceful degradation
  3. Edge Cases: No providers, all providers down, invalid configs
  4. Performance: Route caching, selection speed
  5. Metrics: Routing decision tracking

Mock Strategy:

  • Mock provider health checks
  • Mock load metrics
  • Mock network calls
  • Use pytest fixtures for provider setup

Commands:

# Create test file
touch tests/infrastructure/models/test_router.py

# Test specific module  
tox -e unit -k test_router

# Coverage check
pytest tests/infrastructure/models/test_router.py --cov=src/infrastructure/models/router --cov-report=term-missing

Success Criteria:

  • >85% line coverage for router.py
  • All routing algorithms tested
  • Failover scenarios covered
  • Performance edge cases tested
  • No breaking changes

Critical: Routing logic must be bulletproof. Test all failure modes.
