Hi all, I started having this problem when the driver fails to interact with the app actually its an RDP i am trying to automate the RDP file is opening successfully but not able to click or interact with the RDP like clicking on connect button doesnt work

below is the code

`import unittest from time import sleep

from appium import webdriver from appium.webdriver.extensions import session

class SimpleCalculatorTests(unittest.TestCase):

@classmethod
def setUpClass(self):
    # set up appium
    desired_caps = {}
    desired_caps["app"] = r"C:\jtracker\jailtracker.rdp"
    self.driver = webdriver.Remote(
        command_executor='http://127.0.0.1:4723',
        desired_capabilities=desired_caps)

@classmethod
def tearDownClass(self):
    self.driver.quit()



def test_addition(self):
   self.driver.find_element_by_xpath("/Button[@ClassName=\"Button\"][@Name=\"Connect\"]").click()

    sleep(5)

if name == ‘main’: suite = unittest.TestLoader().loadTestsFromTestCase(SimpleCalculatorTests) unittest.TextTestRunner(verbosity=2).run(suite)

`

below is the error i m getting i console

Hi @nabilalakhani It looks, you are using desktop session directly to control the application. yes, it is slow with xpath or other types of identifiers as well.

I would suggest using desktop session for taking access to the application only, not to control the application. Use this feature to control already opened application through the desktop session. It will not be slow with xpath or any other element identifier.

Try to use this code to get access to the application

desktop_session = self.driver
element  = desktop_session.find_elements_by_xpath('XPATH_TO_SELECT_APPLICATION_HANDLE')
handle = element.get_attribute('NativeWindowHandle')
top_level_window_handle = str(hex(int(handle)))

new_desired_caps = {}
new_desired_caps['appTopLevelWindow'] = top_level_window_handle
new_desired_caps['deviceName] = 'WindowsPC'
new_desired_caps['platformName] = 'Windows'
new_desired_caps['newCommandTimeout] = 3000
self.driver = webdriver.Remote(command_executor='http://127.0.0.1:4723', desired_capabilities=new_desired_caps)

# Test code goes here

There is a known issue with slowness with xpath, better use some other method to locate elements.
