问题：同一套代码，如何同时在不同的手机上执行，测下app在不同手机上兼容性？

解决方法：在一个脚本中同时启动多个Appium服务，让多个设备同时执行。

准备多个设备的capabilities参数

desired_caps = {
    ‘Nokia‘: {
        ‘platformName‘: ‘Android‘,
        ‘appPackage‘: ‘com.XXXX.XXXX‘,
        ‘appActivity‘: ‘.MainActivity‘,
        ‘noReset‘: True,  
        ‘deviceName‘: ‘Nokia 7‘,
        ‘resetKeyboard‘: True,  　　
    },
    ‘Honor‘: {
        ‘platformName‘: ‘Android‘,
        ‘appPackage‘: ‘com.XXXX.XXXX‘,
        ‘appActivity‘: ‘.MainActivity‘,
        ‘noReset‘: True,  
        ‘deviceName‘: ‘Honor 10‘,
        ‘resetKeyboard‘: True  
    },
}

设定Appium服务端口和Bootstrap端口及设备的对应关系

device_info = {
    ‘Nokia‘: {
        ‘port‘: ‘4723‘,
        ‘bpport‘: ‘4750‘,
        ‘uuid‘: ‘xxxxxxxx‘
    },
    ‘Honor‘: {
        ‘port‘: ‘4725‘,
        ‘bpport‘: ‘4752‘,
        ‘uuid‘: ‘xxxxxxxx2‘
    }
}

Mac环境下根据端口杀死进程

需确保appium服务的端口没被占用

def check_port(port):
    a = os.popen("lsof -i tcp:%s"%port)
    t = a.read()
    print(t)
    if port and ‘LISTEN‘ in t:
        b = os.popen("lsof -i tcp:%s |grep -v COMMAND | awk ‘{print $2}‘"%port)
        time.sleep(2)
        pid = b.read()
        os.kill(int(pid),signal.SIGKILL)
        print("Kill pid:%s"%pid)
    else:
        print(‘Port %s is available!‘ % (port))

启动Appium服务

import subprocess
def appium_start(port,bpport,device):
    ‘‘‘appium驱动方法‘‘‘
    host = ‘127.0.0.1‘
    check_port(port)
    time.sleep(3)
    cmd = ‘nohup appium -a ‘ + host + ‘ -p ‘ + str(port) + ‘ -bp ‘ + str(bpport) + ‘ -U‘ + str(device) + ‘ &‘
    print("%s at %s" % (cmd, ctime()))
    ‘‘‘保存Appium日志‘‘‘
    subprocess.Popen(cmd, shell=True, stdout=open(‘./appium_log/‘ + str(port) + ‘.log‘, ‘a‘), stderr=subprocess.STDOUT)

测试用例脚本

def run_app(device, desired):
    port = str(device[‘port‘])
    driver: webdriver = webdriver.Remote(‘http://localhost:%s/wd/hub‘ % port, desired)
    time.sleep(10)
    for i in range(10):
        driver.find_element_by_xpath(‘//android.widget.TextView[@text="XXXX"]‘).click()
        time.sleep(3)
        driver.find_element_by_xpath(‘//android.widget.TextView[@text="XXXX"]‘).click()
        time.sleep(3)

多设备执行

import multiprocessing

device_list = [‘Nokia‘, ‘Honor‘]

appium_starts = []
for i in device_list:
    appium = multiprocessing.Process(target=appium_start, args=(device_info[i][‘port‘],device_info[i][‘bpport‘],device_info[i][‘uuid‘]))
    appium_starts.append(appium)

desired_process = []
for i in device_list:
    desired = multiprocessing.Process(target=run_app, args=(device_info[i], desired_caps[i]))
    desired_process.append(desired)

if __name__ == ‘__main__‘:
    for appium in appium_starts:
        appium.start()
    for appium in appium_starts:
        # 执行进程
        appium.join()
    time.sleep(5)
    for i in desired_process:
        i.start()

Appium多设备并行
