Answer 1

Create a global variable and pass that value in the function as shown below:

class KenLogin(unittest.TestCase):

    def globe(self):

        global driver

        driver = webdriver.Chrome(executable_path='E:\Learning\chromedriver.exe')

    def test_login(self):


        driver.maximize_window()
        driver.implicitly_wait(2000)
        driver.get("http://qa.kenzen.com")
        username = driver.find_element_by_xpath("/html/body/div[1]/div/div[2]/div/div[2]/form/div[1]/input")
        password = driver.find_element_by_xpath("/html/body/div[1]/div/div[2]/div/div[2]/form/div[2]/input")

        username.send_keys("pardeepk@clovity.com")
        password.send_keys("Kenzen@123")

        button = driver.find_element_by_xpath("/html/body/div[1]/div/div[2]/div/div[2]/form/button")

        button.send_keys(Keys.ENTER)
        print("Login Pass")
