[Surekha-tfs]

HI,
I am automating my application using win App driver
i written code like this

import unittest
from appium import webdriver

class AttuneTests(unittest.TestCase):

@classmethod

def setUpClass(self):
    desired_cap = dict(
         platformName= 'Windows', 
         platformVersion = '10',
         deviceName='WindowsPC',
        app= 'C:\\Program Files\\LifeTechnologies\\AttuneNxT\\Attune.exe'
        
    )
    self.driver = webdriver.Remote(
        command_executor='http://127.0.0.1:4723',
        desired_capabilities = desired_cap)
    self.driver.implicitly_wait(30)
    self.driver.maximize_window()
    self.driver.find_element_by_name("Attune™ Acoustic Focusing Cytometer")

def test_attunelogin(self):        
    self.driver.find_element_by_accessibility_id("1962").send_keys("admin")
    self.driver.find_element_by_accessibility_id("1963").send_keys("admin1")
    self.driver.find_element_by_accessibility_id("1964").click()
   
        
@classmethod
def tearDownClass(self):
    self.driver.quit()

if name == 'main':
suite = unittest.TestLoader().loadTestsFromTestCase(AttuneTests)
unittest.TextTestRunner(verbosity=2).run(suite)
