# 集成测试

This topic explains how to run (and extend) PX4's ROS-based integration tests.

注解

MAVSDK Integration Testing is preferred when writing new tests. Use the ROS-based integration test framework for use cases that require ROS (e.g. object avoidance).

All PX4 integraton tests are executed automatically by our Continuous Integration system.

# ROS / MAVROS 测试

# Execute Tests

To run the MAVROS tests:

cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
rostest px4 mavros_posix_tests_iris.launch

test_target is a makefile targets from the set: tests_mission, tests_mission_coverage, tests_offboard and tests_avoidance.

Test can also be executed directly by running the test scripts, located under test/:

rostest px4 mavros_posix_tests_iris.launch gui:=true headless:=false

在 launch/mavros_posix_tests_irisl.launch 中添加测试组中的新条目：

./test/rostest_px4_run.sh mavros_posix_tests_offboard_posctl.test

如上所述运行完整的测试套件。

# 开始仿真
cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
roslaunch px4 mavros_posix_sitl.launch

# 运行测试（在新的 shell 中）：
cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
rosrun px4 mavros_new_test.py

The .test files launch the corresponding Python tests defined in integrationtests/python_src/px4_it/mavros/

# Write a New MAVROS Test (Python)

This section explains how to write a new python test using ROS 1/MAVROS, test it, and add it to the PX4 test suite.

We recommend you review the existing tests as examples/inspiration (integrationtests/python_src/px4_it/mavros/ (opens new window)). The official ROS documentation also contains information on how to use unittest (opens new window) (on which this test suite is based).

To write a new test:

Create a new test script by copying the empty test skeleton below:

#!/usr/bin/env python
# [... LICENSE ...]

#
# @author Example Author <author@example.com>
#
PKG = 'px4'

import unittest
import rospy
import rosbag

from sensor_msgs.msg import NavSatFix

class MavrosNewTest(unittest.TestCase):
    """
    Test description
    """

    def setUp(self):
        rospy.init_node('test_node', anonymous=True)
        rospy.wait_for_service('mavros/cmd/arming', 30)

        rospy.Subscriber("mavros/global_position/global", NavSatFix, self.global_position_callback)
        self.rate = rospy.Rate(10) # 10hz
        self.has_global_pos = False

    def tearDown(self):
        pass

    #
    # General callback functions used in tests
    #
    def global_position_callback(self, data):
        self.has_global_pos = True

    def test_method(self):
        """Test method description"""

        # FIXME: hack to wait for simulation to be ready
        while not self.has_global_pos:
            self.rate.sleep()

        # TODO: execute test

if __name__ == '__main__':
    import rostest
    rostest.rosrun(PKG, 'mavros_new_test', MavrosNewTest)

Run the new test only

Start the simulator:

cd <PX4-Autopilot_clone>
source Tools/simulation/gazebo/setup_gazebo.bash
roslaunch launch/mavros_posix_sitl.launch

Run test (in a new shell):

cd <PX4-Autopilot_clone>
source Tools/simulation/gazebo/setup_gazebo.bash
rosrun px4 mavros_new_test.py

Add new test node to a launch file
- In test/ create a new <test_name>.test ROS launch file.
- Call the test file using one of the base scripts rostest_px4_run.sh or rostest_avoidance_run.sh
(Optional) Create a new target in the Makefile
- Open the Makefile
- Search the Testing section
- Add a new target name and call the test
For example:
```
tests_<new_test_target_name>: rostest
    @"$(SRC_DIR)"/test/rostest_px4_run.sh mavros_posix_tests_<new_test>.test
```

Run the tests as described above.
