Create comprehensive Pytest test suite #12
Conversation
Implemented a solid foundation of unit tests focusing on critical core components: ## Test Infrastructure - conftest.py with comprehensive shared fixtures - Database fixtures (temp_db, db_engine, db_session) - MockMeshCore fixtures - Queue manager fixtures - Test configuration fixtures - Sample data fixtures (events, tags, public keys) - Test data files for various scenarios (valid/invalid tags, sample events) ## Unit Tests (91 tests total) ### test_address_utils.py (44 tests - 100% coverage) - Public key validation and normalization - Prefix extraction and matching - Case-insensitive operations - Integration workflows ### test_rate_limiter.py (29 tests - 95% coverage) - Token bucket algorithm implementation - Burst handling and rate control - Token refill over time - Concurrent access serialization - Edge cases (disabled, slow/fast rates, zero tokens) ### test_debouncer.py (18 tests - 96% coverage) - Command hashing and duplicate detection - Completion tracking and result caching - Waiter notification mechanism - LRU cache eviction - Background cleanup task - TTL and expiry handling ## Coverage Metrics - **Overall**: 25% coverage - **Critical components**: 90%+ coverage - utils/address.py: 100% - queue/debouncer.py: 96% - queue/rate_limiter.py: 95% - database/models.py: 92% ## Future Test Additions The following areas can be expanded for higher coverage: - Config class and argument parsing - MockMeshCore event generation and command handling - API route integration tests (health, nodes, commands, tags) - Database operations (CRUD, migrations) - Event handler and webhook dispatch - CLI command execution (E2E tests) - Full application lifecycle tests ## Running the Tests ```bash # All tests pytest tests/ # With coverage pytest tests/ --cov=meshcore_api --cov-report=html # Specific test file pytest tests/unit/test_rate_limiter.py -v ``` This provides a robust testing foundation that can be extended incrementally.
…management Adds comprehensive tests for the MockMeshCore implementation: ## Test Coverage (15 tests) ### Initialization (4 tests) - Default configuration - Scenario-based initialization - Custom event intervals - Custom GPS parameters ### Lifecycle Management (4 tests) - Node creation on connect - Connect/disconnect cycle - Double-connect safety - Disconnect without connect safety ### Event Generation (2 tests) - Event generation over time - Multiple event types generated ### Event Subscription (2 tests) - Single callback subscription - Multiple subscribers receiving same events ### Node Generation (3 tests) - Correct node count - Unique public keys for all nodes - Valid 64-character hex public keys All tests use the correct MockMeshCore interface: - connect()/disconnect() instead of start()/stop() - subscribe_to_events() for event handlers - _simulated_nodes for generated test nodes Total test suite now has 106 passing tests.
Critical fixes to make fixtures compatible with actual class signatures:
## Config fixture fixes:
- mock_event_interval → mock_min_interval, mock_max_interval
- mock_scenario_loop → mock_loop
- db_retention_days → retention_days
- db_cleanup_interval_hours → cleanup_interval_hours
- log_json → log_format ("text" instead of False)
- enable_metrics → metrics_enabled
- debounce_commands: list → comma-separated string
## MockMeshCore fixture fixes:
- event_interval → min_interval, max_interval
- scenario → scenario_name
- await mock.start() → await mock.connect()
- await mock.stop() → await mock.disconnect()
All 106 tests continue to pass with corrected parameter names.

Pull request overview
This pull request migrates the project from Poetry to PEP 621/Setuptools and introduces a comprehensive test infrastructure for the MeshCore API. The changes establish reusable pytest fixtures, add extensive unit tests for core components, and provide sample data files for testing scenarios.
Key Changes:
- Migration from Poetry to PEP 621-compliant pyproject.toml with Setuptools as the build backend
- Addition of 348 lines of shared pytest fixtures in conftest.py supporting database, API clients, mock objects, and test data
- Creation of 4 comprehensive unit test files covering rate limiting, mock MeshCore, debouncing, and address utilities (totaling 1217 lines)
- Addition of JSON fixture files containing sample events, tags, and invalid data for testing

The test_app_with_auth fixture has async dependencies (mock_meshcore and queue_manager) but is not itself async. This can cause issues since the async fixtures may not be properly initialized when this fixture runs. Consider making this an async fixture using @pytest_asyncio.fixture or ensure the dependencies are available synchronously.

The test checks that limiter._tokens < 0.01 to verify tokens are approximately 0, but this can fail in concurrent scenarios where tokens may have refilled slightly. Consider using assert limiter._tokens <= 0.01 or assert abs(limiter._tokens) < 0.01 for more robust assertions, or check that tokens are below the burst limit rather than near zero.

The test checks that limiter._tokens < 0.01 to verify tokens are approximately 0, but this assertion is fragile. If any time has elapsed during the test, tokens may have refilled slightly above 0.01. Consider using assert limiter._tokens <= 0.01 for a more robust assertion.

This test is incomplete. It checks that available tokens are less than 1.0 but doesn't verify the actual try_acquire behavior with timeout. The test name suggests it should verify timeout behavior, but it only sets up the state without attempting the acquisition that would timeout.

| # Try to acquire with a short timeout (should fail) | |

This pull request introduces new test fixtures and updates the project configuration to migrate from Poetry to PEP 621 and Setuptools. The main changes enable more robust and maintainable testing for the MeshCore API, including reusable pytest fixtures and sample data for events and tags.
Project configuration migration:
pyproject.tomlfrom Poetry to PEP 621 and Setuptools, updating metadata, dependencies, scripts, and build system configuration. This makes the project compatible with standard Python packaging tools and simplifies dependency management.Testing infrastructure improvements:
tests/conftest.pyto support database setup, configuration, FastAPI test clients, mock objects, and sample data for MeshCore API tests. These fixtures enable easier and more consistent test writing.Sample data for tests:
tests/fixtures/sample_events.jsoncontaining representative MeshCore event samples for use in integration and unit tests.tests/fixtures/sample_tags.jsonwith sample node tags, including various value types and realistic data, to support tag-related tests.tests/fixtures/invalid_tags.jsoncontaining examples of malformed or invalid node tags for negative testing scenarios.
