Explore the world of automated web testing with Selenium in Python. This script demonstrates how to navigate to a web page, input login credentials, and verify the appearance of a product title. Get started with Selenium by installing it and dive deeper into web testing using the WebDriver API. For quick reference and commands, check out the Selenium Cheatsheet. WebDriver API documentation can be found here: Selenium WebDriver API.

Install Selenium

pip3 install selenium

(This post uses selenium 4.14.0)

Test Code

• Open https://www.saucedemo.com/
• Input user name and password
• Click the log-in button
• Verify show product title

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()

# Maximize the browser window
driver.maximize_window()

driver.get('https://www.saucedemo.com/')

# Check if the webpage title contains 'Swag Labs'
assert 'Swag Labs' in driver.title

driver.implicitly_wait(2)
logo = driver.find_element(By.CLASS_NAME, "login_logo")
login_button = driver.find_element(By.CLASS_NAME, "btn_action")

# Print the inner HTML of the logo (you can uncomment this for debugging)
# print(logo.get_attribute('innerHTML'))

# Assert that 'Swag Labs' is present in the page source
assert 'Swag Labs' in driver.page_source

# Find the username and password text fields by their IDs
username_textfield = driver.find_element(By.ID, 'user-name')
password_textfield = driver.find_element(By.ID, 'password')

# Clear the username and password text fields and input values
username_textfield.clear()
username_textfield.send_keys('standard_user')

password_textfield.clear()
password_textfield.send_keys('secret_sauce')

login_button.click()

time.sleep(2)
title = driver.find_element(By.CSS_SELECTOR, '.title')
