Test Infrastructure Improvement Summary

Objective

Eliminate skipped tests that were dependent on Redis/PostgreSQL by automatically provisioning test infrastructure.

Problem

  • Before: 24 tests skipped due to missing Redis/PostgreSQL dependencies
  • Tests contained pytest.skip() calls that checked for service availability
  • Manual service setup required before running tests

Solution Implemented

1. Docker Compose Test Configuration

File: docker-compose.test.yml

Created a lightweight Docker Compose configuration specifically for testing: - Redis: Using redis:7-alpine with optimized settings for tests - No persistence (appendonly=no, save="") - Health checks - Exposed on port 6379

  • PostgreSQL: Using postgres:16-alpine
  • Test database: fiml_test
  • Test user/password: fiml_test/fiml_test_password
  • Health checks
  • In-memory storage (tmpfs) for speed
  • Exposed on port 5432

2. Pytest Configuration Updates

File: tests/conftest.py

Implemented automatic container lifecycle management: - Environment Setup: Set test-specific environment variables at module load time - Docker Service Fixture: - Automatically starts Redis & PostgreSQL containers before tests - Waits for services to be healthy (with timeout) - Cleans up containers after test session - Supports --no-docker flag for environments where services are already running - Settings Reload: Clears configuration cache to ensure test settings are used

3. Test Code Cleanup

Script: scripts/remove_test_skips.py

Automated removal of conditional skip patterns: - Removed try/except/pytest.skip() blocks from test files - Tests now expect services to be available - Updated files: - tests/test_cache.py - tests/test_integration.py - tests/test_cache_improved.py

4. Dependencies Added

File: pyproject.toml

Added test dependencies for container management: - psycopg2-binary>=2.9.9 - For PostgreSQL connection testing in fixtures

Results

Before

Skipped: 24 (Redis/PostgreSQL dependent)

After

Skipped: 5 (Ray/Live system dependent - not Redis/PostgreSQL)
- 2 Ray-dependent tests (multi-agent orchestration)
- 2 Live system tests  
- 1 WebSocket provider test

Passed: 260
Failed: 7 (actual test bugs, not infrastructure issues)

Impact

  • 79% reduction in skipped tests (24 → 5)
  • All 19 Redis/PostgreSQL-dependent tests now execute automatically
  • Zero manual setup required for developers
  • Consistent test environment across all machines
  • Faster CI/CD feedback (no more "skipped due to missing service" confusion)

Usage

Run Tests Normally (Auto-starts containers)

pytest tests/

Run Tests with Existing Services

pytest tests/ --no-docker

Test Specific Module

pytest tests/test_cache.py -v

Containersstartup Output

🐳 Starting test containers (Redis & PostgreSQL)...
⏳ Waiting for Redis to be ready...
✅ Redis is ready
⏳ Waiting for PostgreSQL to be ready...
✅ PostgreSQL is ready
✅ All test services are ready

Known Issues

L2Cache Test Failures

6 L2Cache tests fail because the test code expects generic set()/get() methods, but the L2Cache implementation uses domain-specific methods like set_price(), get_price(), set_fundamentals(), etc.

Not a infrastructure issue - these are test code bugs that need to be fixed separately.

Remaining Skipped Tests

5 tests still skipped for valid reasons: - Ray tests (2): Require Ray cluster - different infrastructure - Live system tests (2): Require external API keys/services - WebSocket provider test (1): Requires live market data providers

Future Improvements

  1. Add Ray container to docker-compose.test.yml to eliminate remaining Ray skips
  2. Fix L2Cache test expectations to match actual API
  3. Add mock providers for websocket tests
  4. Consider pytest-docker plugin for more advanced container management
