[nabilalakhani]

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

The exception is different then the original one, is inspect able to find the elements

[nabilalakhani]

The exception is different then the original one, is inspect able to find the elements

i believe its not able to find the element since the execption throwing at below line of code while trying to find the window name

    appWindow = driver.find_element_by_name("Remote Desktop Connection")

Traceback (most recent call last): File "C:/Users/Gamer/PycharmProjects/pythonProject2/test2.py", line 25, in setUpClass appWindow = driver.find_element_by_name("Remote Desktop Connection")

also its not able to find any window handles names on below line of code

    print('Appium handles ', driver.window_handles)

output : Appium handles []

can you please suggest something on this

[nabilalakhani]

The exception is different then the original one, is inspect able to find the elements

hey so now i tried some tweaks on below code and it worked but the problem is its taking too long time like 20-30 seconds to click and sendkeys even thought i dont put waits why it takes so much time perform a action please find code below

` import subprocess 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
    global driver

    desired_caps = {}
    desired_caps["platformName"] = "Windows"
    desired_caps["app"] = "Root"
    self.driver = webdriver.Remote(
        command_executor='http://127.0.0.1:4723',
        desired_capabilities=desired_caps)

    self.driver.quit()

def getresults(self):

    displaytext = displaytext.lstrip(' ')
    return displaytext

def test_connect(self):

    self.driver.find_element_by_xpath("//Button[@ClassName=\"Button\"][@Name=\"Connect\"]").click()
    self.driver.find_element_by_xpath("//Edit[@Name=\"Password\"][starts-with(@AutomationId,\"PasswordField_\")]").send_keys("pass")
    self.driver.find_element_by_xpath("//Button[@Name=\"OK\"][@AutomationId=\"OkButton\"]").click()

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

[shoaibmansoor]

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)
