[PYTHON] Automatic login to ServiceNow with Selenium Web Driver

◆ Overview

• I tried to log in to ServiceNow automatically using Selenium WebDriver, which is used for Web UI test automation.

◆ Operating environment

• OS: Windows10
• Python version: 3.8.0

◆ Preparation

ServiceNow instance creation

• You can create an instance for developers by registering an account from the ServiceNow Developers page.
• When the creation is completed, the instance URL and the initial information of the admin account will be displayed, so be sure to make a note of it.

Python execution environment preparation

• Download and install the installer from Python's official website.
• Make sure pip is included.

Preparing Selenium

• Install Selenium with pip.
  • > pip install selenium
• Download the driver for the browser you want to run from Selenium official website.
• This time, to run on Google Chrome, download "Google Chrome Driver".
• Place the downloaded "chromedriver.exe" in any location.

◆ Try operating ServiceNow

Launch browser

• Specify the browser as Google Chrome and start it.
• By the way, maximize the window

from selenium import webdriver

#Launch Google Chrome
driver = webdriver.Chrome(executable_path = 'Chrome Driver path')
#Maximize the window
driver.maximize_window()

Access the ServiceNow login page

• Specify the URL for each instance to access.

#Access the ServiceNow login page
driver.get('https://<ServiceNow instance name>.service-now.com/')
driver.implicitly_wait(20)

Get elements of login form

• Since the login form part is in the iframe, if you specify the id as it is, it will not be found and an error will be thrown out.
• It is necessary to get the element of iframe first and move the frame with switch_to_frame.
• When the operation is finished, use switch_to.default_content () to exit the iframe.

#Get the iframe element that contains the login form
login_iframe = driver.find_element_by_xpath("//*[@id='gsft_main']")
#Move into the specified iframe
driver.switch_to_frame(login_iframe)

#Get elements of user name form&Enter user name
user_name_form = driver.find_element_by_id('user_name')
user_name_form.send_keys("<username>")

#Get password form elements&password input
password_form = driver.find_element_by_id('user_password')
password_form.send_keys("<password>")

#Get login button elements&Click login button
login_button = driver.find_element_by_id('sysverb_login')
login_button.click()

driver.implicitly_wait(20)

#Exit the iframe
driver.switch_to.default_content()
