Parallel usage results in a "socket hang up" error. systemPort have set but still have the problem.

[Underson888]

Here's my code:

python

from appium import webdriver from appium.webdriver.common.touch_action import TouchAction import threading

Device 1's configuration

desired_caps1 = { "appium:appActivity": ".Settings", "appium:appPackage": "com.android.settings", "appium:automationName": "uiautomator2", "appium:udid": "xxxx", "platformName": "Android", "appium:systemPort": 8310 }

Device 2's configuration

desired_caps2 = { "appium:appActivity": ".Settings", "appium:appPackage": "com.android.settings", "appium:automationName": "uiautomator2", "appium:udid": "192.168.137.58:5555", "platformName": "Android", "appium:systemPort": 8322 }

def run_test_on_device(desired_caps): driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps) # Corrected URL

width = driver.get_window_size()["width"]
height = driver.get_window_size()["height"]

action = TouchAction(driver)
action.tap(x=width // 2, y=height // 2).perform()

driver.quit()

Use threading for parallel execution

thread1 = threading.Thread(target=run_test_on_device, args=(desired_caps1,)) thread2 = threading.Thread(target=run_test_on_device, args=(desired_caps2,))

thread1.start() thread2.start()

thread1.join() thread2.join()

I have set the different systemPort for each devices, but I still have the problem.

How can I sove that, I'm very need to be solved, thanks.

Could you share the appium log as well? (as GIST)

Ok,bro. This is the link:https://gist.github.com/Underson888/8871bca07b3241d7aa6f810e9a7bc16c

Did they work with a single thread? The port config itself looks working

Yes,each device is controlled by a single thread,just like the code mentioned.

[Underson888]

thread1 = threading.Thread(target=run_test_on_device, args=(desired_caps1,)) thread2 = threading.Thread(target=run_test_on_device, args=(desired_caps2,))

thread1.start() thread2.start()

thread1.join() thread2.join()

Is it correct for the driver?
