Python+Appium UI自动化代码获取Android多设备信息以及包名

　　使用appium运行UI自动化代码时，若在脚本中固定写死设备信息，那么每次更换测试设备，就需要在脚本中修改很多东西，比较麻烦，

以下代码可以通过脚本自动获取设备信息：devicesid、deviceName、platformVersion（包含获取单个或多个设备信息）以及包名，具体代码图如下：

import os, re
import subprocess

# 项目根路径
BaseDIr = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))

def get_app_devicesId():
# 获取一个设备的devicesid
readDeviceId = list(os.popen('adb devices').readlines())
deviceId = re.findall(r'^\w*\b', readDeviceId[1])[0]
return deviceId

def get_app_devices():
# 获取多个设备devicesId
lists = os.popen('adb devices').read()
devices = lists.strip().split('\n')
devices_list = []
for i in range(1, len(devices)):
device = (devices[i].split('\t')[0])
devices_list.append(device)
return devices_list

def get_devices_version():
# 获取单个系统版本号
cmd1 = 'adb shell getprop ro.build.version.release'
deviceAndroidVersion = list(os.popen(cmd1).readlines())
deviceVersion = re.findall(r'^\w*\b', deviceAndroidVersion[0])[0]
return deviceVersion

def get_devices_info(devices_uuid):
# 获取多设备信息
devices_info = []
cmd1 = 'adb -s {} shell getprop ro.product.model'
cmd2 = 'adb -s {} shell getprop ro.build.version.release'
if devices_uuid:
for de in devices_uuid:
device_model = os.popen(cmd1.format(de)).read()
deviceos_version = os.popen(cmd2.format(de)).read()
devices_info.append((de, device_model.strip('\n'), deviceos_version.strip('\n')))
return devices_info

# 获取测试的包的package
def get_appPackage(apkPath):
appLocation = BaseDIr + apkPath
if os.path.exists(appLocation):
appPackageAdb = list(os.popen('aapt dump badging ' + appLocation).readlines())
appPackage = re.findall(r'\'com\w*.*?\'', appPackageAdb[0])[0]
return appPackage

if __name__ == '__main__':
# 打印设备信息
devices_uuid = get_app_devices()
print(get_devices_info(devices_uuid))

　　执行结果

[('c1e5c96', 'ONEPLUS A6013', '10')]
'com.wm.dmall'

　　引包写入desiredCaps中，代码考虑多设备情况：

from common import get_android_infos as andriod_devices

if __name__ == '__main__':

devices_list = andriod_devices.get_app_devices()  # 获取设备devices List
devices_info = andriod_devices.get_devices_info(devices_list)  # 获取设备信息
appPackage = andriod_devices.get_appPackage("/app_package/D.apk")    # 获取appPackage

# 根据获取到的设备信息开始写入desiredCaps中，以字典的形式写入
desiredCaps = {}
if devices_info:
for de in devices_info:
desiredCaps = {
'platformName': 'Android',
'platformVersion': '{}'.format(de[2]),
'deviceName': '{}'.format(de[1]),
'udid': '{}'.format(de[0]),
'automationName': 'UiAutomator2',
'appPackage': 'com.wm.dmall',
'appActivity': 'com.wm.dmall.LaunchActivity',
'noReset': 'False'
}
