Integration Tests for Pmini SDK

This directory contains integration tests for the Pmini SDK Python library.

Test Structure

• conftest.py - Pytest configuration and fixtures
• test_basic.py - Basic tests that don't require simulation
• test_connection.py - Connection tests that require simulation
• run_integration_tests.py - Test runner script

Prerequisites

1. Install dependencies:

pip install pytest pytest-cov

2. Install the SDK:

pip install -e .

Running Tests

Note

For the integration testing, autopilot simulation is required. You can use this repository to start the simulation: https://gitlab.com/regislab/pathfindermini/pf_mini_gazebo

git clone [e-mail]:regislab/pathfindermini/pf_mini_gazebo.git && cd pf_mini_gazebo

Launch the simulation with the following command

make run

Basic Tests (No Simulation Required)

# Run basic tests only
python -m pytest test/test_basic.py -v

# Or use the test runner
python test/run_integration_tests.py --test-path test/test_basic.py

Connection Tests (Requires Simulation)

# Start your simulation container first, then:
python -m pytest test/test_connection.py -v

All Tests

# Run all tests
python -m pytest test/ -v

With Markers

# Run only integration tests
python -m pytest test/ -m integration

# Run only connection tests
python -m pytest test/ -m connection

# Exclude slow tests
python -m pytest test/ -m "not slow"

Test Configuration

The tests are configured to connect to a simulation running on:

• Host: 192.168.4.1
• Port: 8080
• Protocol: UDP

You can modify the connection settings in conftest.py if your simulation uses different parameters.

Test Categories

Basic Tests (test_basic.py)

• SDK import verification
• Configuration object creation
• Enum availability
• Logging setup

Connection Tests (test_connection.py)

• Connection establishment
• Connection stability
• MAVLink client functionality
• Optical flow data availability
• Connection timeout handling
• Connection recovery

Adding New Tests

1. Create a new test file: test_<feature>.py
2. Use the existing fixtures from conftest.py
3. Add appropriate markers to your tests
4. Follow the existing test patterns

Example:

import pytest
import logging

class TestNewFeature:
    @pytest.mark.integration
    def test_new_feature(self, pmini_instance, wait_for_connection):
        logger = logging.getLogger(__name__)
        logger.info("Testing new feature")
        
        # Your test logic here
        assert True
        logger.info("✅ New feature test passed")

Troubleshooting

Connection Timeout

If tests fail with connection timeout:

1. Ensure your simulation container is running
2. Check that the simulation is listening on the correct port
3. Verify network connectivity between test environment and simulation

Import Errors

If you get import errors:

1. Make sure the SDK is installed: pip install -e .
2. Check that all dependencies are installed: pip install -r requirements.txt

Test Failures

• Check the logs for detailed error messages
• Use -v flag for verbose output
• Use -s flag to see print statements
