Test Infrastructure

Test Package

• Created linux-hello-tests package in workspace for integration tests
• Tests are organized in tests/ directory at project root

Running Tests

All Tests

cargo test

Unit Tests Only

cargo test --lib

Integration Tests

cargo test --package linux-hello-tests

Specific Test Suite

cargo test --package linux-hello-tests --test camera_test
cargo test --package linux-hello-tests --test detection_test
cargo test --package linux-hello-tests --test cli_test

Phase 1 Test Script

bash tests/phase1_test.sh

Known Limitations

1. ONNX Models: ML models are not yet integrated (waiting for ort 2.0 stable)
2. Hardware Requirements: Some tests require actual camera hardware
3. IR Emitter: IR emitter control is hardware-specific and may not work on all devices
4. Face Detection: Currently using simple placeholder algorithm, not ML-based

Next Steps (Phase 2)

1. Integrate ONNX Runtime for face detection models
2. Implement face embedding extraction
3. Add template matching and storage
4. Implement PAM-daemon communication
5. Add enrollment flow
6. Add authentication flow
