# SaltyBot Integration Test Suite (Issue #504)
# saltybot_tests — Integration Test Suite (Issue #504)
Comprehensive automated testing for the SaltyBot full stack. Verifies all nodes start, topics publish, TF tree is complete, and system remains stable.
Complete ROS2 system integration testing for SaltyBot full-stack bringup.
## What's Tested
## Test Files
### Main Test (test_launch.py)
- ✅ All critical nodes start within 30 seconds
- ✅ Required topics are advertised
- ✅ TF tree is complete
- ✅ Sensor data publishing (odometry, IMU, LIDAR, camera)
- ✅ Person detection topic available
- ✅ No immediate node crashes
- ✅ **System stability for 30 seconds** (all nodes remain alive)
| File | Description |
|------|-------------|
| `test_launch.py` | launch_testing: full stack in follow mode, 30s stability |
| `test_subsystems.py` | Sensor health, perception, navigation, rosbridge |
| `test_slam_nav2.py` | SLAM (RTAB-Map) + Nav2 lifecycle nodes (indoor mode) |
| `test_controls_pipeline.py` | cmd_vel_mux, motor protection, accel limiter, e-stop |
| `test_audio_monitoring.py` | Audio pipeline, VAD, health monitor, diagnostics, docking |
### Subsystem Tests (test_subsystems.py)
- **Sensor Health**: LIDAR scan rate, RealSense RGB/depth, IMU publishing
- **Perception**: YOLOv8 person detection node alive and publishing
- **Navigation**: Odometry continuity, TF broadcasts active
- **Communication**: Rosbridge server running, critical topics bridged
## Coverage
## Running Tests
| Subsystem | Nodes | Topics | Services |
|-----------|-------|--------|----------|
| Sensors | LIDAR, RealSense, IMU | /scan, /camera/*, /odom | — |
| SLAM | rtabmap | /rtabmap/map, /rtabmap/odom | /saltybot/save_map |
| Nav2 | planner, controller, bt_navigator | /global_costmap, /plan | /compute_path_to_pose |
| Perception | yolo_node | /person/detections | — |
| Controls | mux, accel_limiter, smoother | /cmd_vel, /e_stop | — |
| Audio | audio_pipeline, vad | /audio/state, /audio_level | — |
| Monitoring | health_monitor, watchdog | /system_health, /diagnostics | — |
| Docking | docking_node | /docking_status | /saltybot/dock, /undock |
| Comms | rosbridge_websocket | /tf, /odom bridged | — |
## Running
### Quick Test (follow mode, ~45 seconds)
```bash
cd jetson/ros2_ws
# Build
colcon build --packages-select saltybot_tests
source install/setup.bash
# Run all tests
pytest install/saltybot_tests/lib/saltybot_tests/../../../share/saltybot_tests/ -v -s
# Follow mode tests (no hardware)
ros2 launch saltybot_bringup full_stack.launch.py mode:=follow enable_bridge:=false &
sleep 15
pytest test/ -v --ignore=test/test_slam_nav2.py --tb=short
# Or directly
ros2 launch launch_testing launch_test.py ./src/saltybot_tests/test/test_launch.py
# Indoor mode tests (SLAM + Nav2)
ros2 launch saltybot_bringup full_stack.launch.py mode:=indoor enable_bridge:=false &
sleep 25
pytest test/test_slam_nav2.py -v --tb=short
# Full launch_testing suite
ros2 launch launch_testing launch_test.py test/test_launch.py
```
### Individual Test File
```bash
pytest src/saltybot_tests/test/test_launch.py -v -s
pytest src/saltybot_tests/test/test_subsystems.py -v
```
### With colcon test
```bash
colcon test --packages-select saltybot_tests --event-handlers console_direct+
```
## Test Modes
### Follow Mode (Default - Fastest)
- ✅ Sensors: RPLIDAR, RealSense D435i
- ✅ Person detection: YOLOv8n
- ✅ Person follower controller
- ✅ UWB positioning
- ✅ Rosbridge WebSocket
- ❌ SLAM (not required)
- ❌ Nav2 (not required)
- **Startup time**: ~30 seconds
- **Best for**: Quick CI/CD validation
### Indoor Mode (Full Stack)
- Everything in follow mode +
- ✅ SLAM: RTAB-Map with RGB-D + LIDAR
- ✅ Nav2 navigation stack
- **Startup time**: ~45 seconds
- **Best for**: Complete system validation
## Test Output
### Success Example
```
test_launch.py::TestSaltyBotStackLaunch::test_01_critical_nodes_start PASSED
test_launch.py::TestSaltyBotStackLaunch::test_02_required_topics_advertised PASSED
test_launch.py::TestSaltyBotStackLaunch::test_03_tf_tree_complete PASSED
test_launch.py::TestSaltyBotStackLaunch::test_04_odometry_publishing PASSED
test_launch.py::TestSaltyBotStackLaunch::test_05_sensors_publishing PASSED
test_launch.py::TestSaltyBotStackLaunch::test_06_person_detection_advertised PASSED
test_launch.py::TestSaltyBotStackLaunch::test_07_no_immediate_crashes PASSED
test_launch.py::TestSaltyBotStackLaunch::test_08_system_stability_30s PASSED
```
### Failure Example
```
FAILED test_launch.py::TestSaltyBotStackLaunch::test_02_required_topics_advertised
AssertionError: Required topics not advertised: ['/uwb/target', '/person/detections']
Advertised: ['/camera/color/image_raw', '/scan', ...]
```
## CI Integration
Add to your CI/CD pipeline:
```yaml
- name: Run Integration Tests
run: |
source /opt/ros/humble/setup.bash
colcon build --packages-select saltybot_tests
colcon test --packages-select saltybot_tests --event-handlers console_direct+
```
## Troubleshooting
### Nodes Don't Start
- Check hardware connections: RPLIDAR, RealSense, UWB anchors
- Review full_stack.launch.py for required serial ports
- Check logs: `ros2 run rqt_graph rqt_graph`
### Topics Missing
- Verify nodes are alive: `ros2 node list`
- Check topic list: `ros2 topic list`
- Inspect topics: `ros2 topic echo /scan` (first 10 messages)
### TF Tree Incomplete
- Verify robot_description is loaded
- Check URDF: `ros2 param get /robot_state_publisher robot_description`
- Monitor transforms: `ros2 run tf2_tools view_frames.py`
### Sensor Data Not Publishing
- **RPLIDAR**: Check `/dev/ttyUSB0` permissions
- **RealSense**: Check USB connection, device list: `rs-enumerate-devices`
- **IMU**: Verify RealSense firmware is current
### Test Timeout
- Integration tests default to 120s per test
- Increase timeout in `conftest.py` if needed
- Check system load: `top` or `htop`

## Key Features
### NodeChecker
Waits for nodes to appear in the ROS graph. Useful for verifying startup sequence.
### TFChecker
Ensures TF tree is complete (all required frame transforms exist).
### TopicMonitor
Tracks message counts and publishing rates for sensors.
## Contributing
Add new integration tests in `test/`:
1. Create `test_feature.py` with `unittest.TestCase` subclass
2. Use `NodeChecker`, `TFChecker`, `TopicMonitor` helpers
3. Follow test naming: `test_01_critical_functionality`
4. Run locally: `pytest test/test_feature.py -v -s`
## Performance Targets
| Component | Startup | Rate | Status |
|-----------|---------|------|--------|
| Robot description | <1s | N/A | ✅ |
| RPLIDAR driver | <2s | 10 Hz | ✅ |
| RealSense | <2s | 30 Hz | ✅ |
| Person detection | <6s | 5 Hz | ✅ |
| Follower | <9s | 10 Hz | ✅ |
| Rosbridge | <17s | N/A | ✅ |
| Full stack stable | 30s | N/A | ✅ |
