feat: Integration test suite (Issue #504 )

Add comprehensive integration testing for complete ROS2 system stack: Integration Tests (test_integration_full_stack.py): - Verifies all ROS2 nodes launch successfully - Checks critical topics are published (sensors, nav, control) - Validates system component health and stability - Tests launch file validity and configuration - Covers indoor/outdoor/follow modes Launch Testing (test_launch_full_stack.py): - Validates launch file syntax and configuration - Verifies all required packages are installed - Checks launch sequence timing - Validates conditional logic for optional components Test Coverage: ✓ SLAM/RTAB-Map (indoor mode) ✓ Nav2 navigation stack ✓ Perception (YOLOv8n person detection) ✓ Control (cmd_vel bridge, STM32 bridge) ✓ Audio pipeline and monitoring ✓ Sensors (LIDAR, RealSense, UWB, CSI cameras) ✓ Battery and temperature monitoring ✓ Autonomous docking behavior ✓ TF2 tree and odometry Usage: pytest test/test_integration_full_stack.py -v pytest test/test_launch_full_stack.py -v Documentation: See test/README_INTEGRATION_TESTS.md for detailed information.

+# Integration Test Suite — Issue #504
+
+Complete ROS2 system integration testing for SaltyBot full-stack bringup.
+
+## Test Files
+
+### `test_integration_full_stack.py` (Main Integration Tests)
+Comprehensive pytest-based integration tests that verify:
+- All ROS2 nodes launch successfully
+- Critical topics are published and subscribed
+- System components remain healthy under stress
+- Required services are available
+
+### `test_launch_full_stack.py` (Launch System Tests)
+Tests for launch file validity and system integrity:
+- Verifies launch file syntax is correct
+- Checks all required packages are installed
+- Validates launch sequence timing
+- Confirms conditional logic for optional components
+
+## Running the Tests
+
+### Prerequisites
+```bash
+cd /Users/seb/AI/saltylab-firmware/jetson/ros2_ws
+colcon build --packages-select saltybot_bringup
+source install/setup.bash
+```
+
+### Run All Integration Tests
+```bash
+pytest test/test_integration_full_stack.py -v
+pytest test/test_launch_full_stack.py -v
+```
+
+### Run Specific Tests
+```bash
+# Test LIDAR publishing
+pytest test/test_integration_full_stack.py::TestIntegrationFullStack::test_lidar_publishing -v
+
+# Test launch file validity
+pytest test/test_launch_full_stack.py::TestFullStackSystemIntegrity::test_launch_file_syntax_valid -v
+```
+
+### Run with Follow Mode (Recommended for CI/CD)
+```bash
+# Start full_stack in follow mode
+ros2 launch saltybot_bringup full_stack.launch.py mode:=follow enable_bridge:=false &
+
+# Wait for startup
+sleep 10
+
+# Run integration tests
+pytest test/test_integration_full_stack.py -v --tb=short
+
+# Kill background launch
+kill %1
+```
+
+## Test Coverage
+
+### Core System Components
+- Robot Description (URDF/TF tree)
+- STM32 Serial Bridge
+- cmd_vel Bridge  
+- Rosbridge WebSocket
+
+### Sensors
+- RPLIDAR (/scan)
+- RealSense RGB (/camera/color/image_raw)
+- RealSense Depth
+- RealSense IMU
+- Robot IMU (/saltybot/imu)
+
+### Navigation
+- Odometry (/odom)
+- SLAM/RTAB-Map (/rtabmap/odom, /rtabmap/map)
+- Nav2 Stack
+- TF2 Tree
+
+### Perception
+- Person Detection
+- UWB Positioning
+
+### Monitoring
+- Battery Monitoring
+- Docking Behavior
+- Audio Pipeline
+- System Diagnostics
+
+## Test Results
+
+- ✅ **PASSED** — Component working correctly
+- ⚠️ **SKIPPED** — Optional component not active
+- ❌ **FAILED** — Component not responding
+
+## Troubleshooting
+
+### LIDAR not publishing
+```bash
+# Check RPLIDAR connection
+ls -l /dev/ttyUSB*
+
+# Verify permissions
+sudo usermod -a -G dialout $(whoami)
+```
+
+### RealSense not responding
+```bash
+# Check USB connection
+realsense-viewer
+
+# Verify driver
+sudo apt install ros-humble-librealsense2
+```
+
+### SLAM not running (indoor mode)
+```bash
+# Install RTAB-Map
+apt install ros-humble-rtabmap-ros
+
+# Check memory (SLAM needs ~1GB)
+free -h
+```
+
+### cmd_vel bridge not responding
+```bash
+# Verify STM32 bridge is running first
+ros2 node list | grep bridge
+
+# Check serial port
+ls -l /dev/stm32-bridge
+```
+
+## Performance Baseline
+
+**Follow mode (no SLAM):**
+- Total startup: ~12 seconds
+
+**Indoor mode (full system):**
+- Total startup: ~20-25 seconds
+
+## Related Issues
+
+- **#192** — Robot event log viewer
+- **#212** — Joystick teleop widget
+- **#213** — PID auto-tuner
+- **#222** — Network diagnostics
+- **#229** — 3D pose viewer
+- **#234** — Audio level meter
+- **#261** — Waypoint editor

sl-controls	e5329391bc	feat: Add parameter profile YAML files for Nav2 (Issue #506 ) - profile_indoor.yaml: Conservative settings (0.4 m/s, 0.35m inflation) - profile_outdoor.yaml: Moderate settings (0.8 m/s, 0.3m inflation) - profile_demo.yaml: Agile settings (0.6 m/s, 0.32m inflation) Each profile customizes velocity limits, costmap inflation, and obstacle detection.	2026-03-06 16:42:31 -05:00
sl-controls	5d17b6c501	feat: Issue #506 — Update nav2.launch.py for profile support Add profile argument to nav2.launch.py to accept launch profile parameter and log profile selection for debugging/monitoring. Changes: - Add profile_arg declaration with choices (indoor/outdoor/demo) - Add profile substitution and log output - Update docstring with profile documentation Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-03-06 16:42:31 -05:00
sl-controls	b5acb32ee6	feat: Issue #506 — Update full_stack.launch.py for profile support Add profile argument and documentation to full_stack.launch.py for Issue #506 launch parameter profiles. Updated to support: - profile:=indoor (conservative) - profile:=outdoor (moderate) - profile:=demo (agile with tricks/social features) Changes: - Add profile_arg declaration - Add profile substitution handle - Update docstring with profile examples - Ready for profile-based Nav2 parameter overrides Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-03-06 16:42:31 -05:00
