老师，多线程启动脚本，只有一个app会找到页面元素，另一个就找不到页面元素了

Question

我启动后两个都可以打开慕课网进入登陆界面

模拟器1输入账号密码登录模拟器2就报错说找不到页面元素没法输入账号密码
有时两个反过来模拟器2找得到模拟器1找不到

这是base_driver的代码

class BaseDriver():
def android_driver(self, i):
ini = ReadIni(node=“server_port”, file_name=r"D:\测试\自动化测试\App自动化测试\Appnium\config\userconfig.ini")
deviceName = ini.get_value(“devices” + str(i))
port = ini.get_value(“appium_port” + str(i))
capabilities = {
“platformName”: “Android”,
“automationName”: “UiAutomator2”,
“deviceName”: deviceName,
“app”: “D:\测试\APPnium\mukewang.apk”,
“noReset”: “true”
}
driver = webdriver.Remote(“127.0.0.1:” + port +"/wd/hub", capabilities)
time.sleep(5)
return driver

这是case页面的代码

class ParamTestCase(unittest.TestCase):
def init(self, methodName=‘runTest’, param=None):
super(ParamTestCase, self).init(methodName)
self.param = param
global params
params = param

class LoginCaseTest(ParamTestCase):

@classmethod
def setUpClass(cls):
    base_driver = BaseDriver()
    cls.driver = base_driver.android_driver(params)
    time.sleep(10)
    cls.login_business = LoginBusiness(cls.driver)

def test_login_pass(self):
    self.login_business.login_pass()

def get_suite(i):
suite = unittest.TestSuite()
# for name in testnames:
suite.addTest(LoginCaseTest(“test_login_pass”, param=i))
unittest.TextTestRunner().run(suite)

if name == “main”:
se = Server()
se.start_server_thread()
threads = []
for i in range(2):
t = threading.Thread(target=get_suite, args=(i,))
threads.append(t)
for j in threads:
j.start()

老师，我手动打开的2个appium服务，还是报这个错

selenium.common.exceptions.StaleElementReferenceException: Message: The element 'By.id: cn.com.open.mooc:id/login_lable' does not exist in DOM anymore

他还是找不到元素啊，你看，右边的模拟器成功登录，左边的报错

import multiprocessing
import time
from appium import webdriver


def base_driver(i):
   if i == 0:
       capabilities = {
           "platformName": "Android",
           # "automationName": "UiAutomator2",
           "deviceName": "62001",
           "app": "D:\\测试\\APPnium\\mukewang.apk",
           "noReset": "true"
       }
       driver = webdriver.Remote("127.0.0.1:4700/wd/hub", capabilities)
   else:
       capabilities = {
           "platformName": "Android",
           # "automationName": "UiAutomator2",
           "deviceName": "62025",
           "app": "D:\\测试\\APPnium\\mukewang.apk",
           "noReset": "true"
       }
       driver = webdriver.Remote("127.0.0.1:4701/wd/hub", capabilities)
   time.sleep(5)
   return driver


def test_case01(i):
   driver = base_driver(i)
   time.sleep(10)
   driver.find_element_by_id("cn.com.open.mooc:id/account_edit").send_keys('15226499639')
   driver.find_element_by_id("cn.com.open.mooc:id/password_edit").send_keys('qwer123456')
   driver.find_element_by_id("cn.com.open.mooc:id/login_lable").click()


if __name__ == "__main__":
   threads = []
   for i in range(2):
       t = multiprocessing.Process(target=test_case01, args=(i,))
       threads.append(t)
   for j in threads:
       j.start()

这就是全部代码，没有导入其他文件了，还是报错，我也不知道怎么回事，请老师指点

定位元素失败定位方式是:(‘id’, ‘cn.com.open.mooc:id/account_edit’) 1、这个后面又讲解多进程执行，你先往后看。

• 提问者 weixin_慕雪2209780 #1

  老师，我往后面看了，多进程也一样的，但是模拟器我关了前面的，就可以同时运行两个模拟器，但是最多10分钟，又会报错，早不到元素，我又得新开一个模拟器

• Mushishi 回复 提问者 weixin_慕雪2209780 #2

  我猜测还是你得传递参数那里混淆了，我建议你先用两个最简单得driver生成了，然后就手动启动俩服务端口，然后通过多进程直接去跑 生成得driver然后去定位元素。然后去看是否报错

• 提问者 weixin_慕雪2209780 回复 Mushishi #3

  试了试，还是报错，没得用，找不到原因
