综合测试
官网英文原文地址:http://dev.px4.io/tutorial-integration-testing.html
这是综合测试,测试会自动执行(Jenkins CI)。
ROS / MAVROS测试
前提:
- SITL仿真
- Gazebo
- ROS and MAVROS
执行测试
运行完整的MAVROS测试套件:
cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
rostest px4 mavros_posix_tests_iris.launch
或者使用GUI查看:
rostest px4 mavros_posix_tests_iris.launch gui:=true headless:=false
编写新的MAVROS测试 (Python)
目前处于早期阶段,采用了很多简化测试(helper classes/methods etc.)。
1.) 创建新的测试脚本
测试脚本位于integrationtests/python_src/px4_it/mavros/
,可以参考这些脚本文件。或者查阅ROS官方文档学习如何使用unittest。
空的测试框架:
#!/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)
2.) 只运行新的测试
# Start simulation
cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
roslaunch px4 mavros_posix_sitl.launch
# Run test (in a new shell):
cd <Firmware_clone>
source integrationtests/setup_gazebo_ros.bash $(pwd)
rosrun px4 mavros_new_test.py
3.) 添加新的测试结点到launch文件
在launch/mavros_posix_tests_irisl.launch
中的测试组中添加新的条目:
<group ns="$(arg ns)">
[...]
<test test-name="mavros_new_test" pkg="px4" type="mavros_new_test.py" />
</group>
按照前文所述方法运行完整测试套件。
