feat: Set up comprehensive Python testing infrastructure

[llbbl]

Add Complete Python Testing Infrastructure

Summary

This PR sets up a comprehensive testing infrastructure for the Python project, migrating from basic requirements.txt to a full Poetry-managed environment with extensive testing capabilities.

Changes Made

Package Management

• ✅ Poetry Setup: Added complete pyproject.toml with Poetry configuration
• ✅ Dependency Migration: Migrated all dependencies from requirements.txt to Poetry
• ✅ Development Dependencies: Added testing-specific dependencies as dev-only packages

Testing Framework

• ✅ Pytest Configuration: Complete pytest setup with discovery patterns and strict options
• ✅ Coverage Reporting: Configured 80% coverage threshold with HTML, XML, and terminal reports
• ✅ Custom Markers: Added unit, integration, and slow test markers for organization

Test Dependencies Added

pytest = "^7.4.0"          # Main testing framework
pytest-cov = "^4.1.0"      # Coverage reporting
pytest-mock = "^3.11.1"    # Mocking utilities

Directory Structure

tests/
├── __init__.py
├── conftest.py           # Shared fixtures
├── unit/
│   └── __init__.py
├── integration/
│   └── __init__.py
└── test_infrastructure.py  # Validation tests

Shared Fixtures

Created comprehensive conftest.py with fixtures for:

• temp_dir - Temporary directory management
• mock_config - Mock configuration objects
• mock_request/mock_response - Flask testing utilities
• mock_websocket - WebSocket connection mocking
• sample_data - Common test data structures

Configuration Highlights

• Coverage: 80% threshold, excludes test files and common patterns
• Test Discovery: Automatic discovery of test_*.py and *_test.py files
• Strict Mode: Enabled strict markers and configuration validation
• Output: Verbose reporting with missing coverage lines highlighted

How to Use

Running Tests

# Install dependencies
poetry install

# Run all tests
poetry run pytest

# Run tests with coverage
poetry run pytest --cov

# Run specific test types
poetry run pytest -m unit
poetry run pytest -m integration
poetry run pytest -m slow

# Run tests in specific directories
poetry run pytest tests/unit/
poetry run pytest tests/integration/

Alternative Commands

Both poetry run test and poetry run tests are configured as shortcuts.

Coverage Reports

• Terminal: Displayed after each test run
• HTML: Generated in htmlcov/ directory
• XML: Generated as coverage.xml for CI/CD integration

Development Notes

Dependencies Management

• Production dependencies are in main [tool.poetry.dependencies]
• Testing dependencies are in [tool.poetry.group.test.dependencies]
• Lock file (poetry.lock) should be committed to ensure reproducible builds

Git Configuration

Updated .gitignore to exclude:

• Testing artifacts (.pytest_cache/, htmlcov/, coverage.xml)
• Development environments and IDE files
• Claude Code settings (.claude/*)

Validation

The infrastructure includes validation tests (test_infrastructure.py) that verify:

• ✅ Pytest is working correctly
• ✅ Python version compatibility (3.8+)
• ✅ Project structure is correct
• ✅ All fixtures are available and functional
• ✅ Test markers are properly configured

Ready for Development

The testing infrastructure is now complete and ready for developers to:

1. Write unit tests in tests/unit/
2. Write integration tests in tests/integration/
3. Use shared fixtures from conftest.py
4. Run tests with comprehensive coverage reporting
5. Organize tests using custom markers

All validation tests pass, confirming the infrastructure is properly configured and functional.

sir did u just throw an LLM at this

trying to get testing setup for all public repos. I built a wrapper around CC to do the setup. keeping track of what gets merged. haven't decided on phase 2 (writing the tests) yet.
