First Selenium script in Selenium Python

Introduction

Selenium helps you control a web browser automatically. This lets you test websites like a real user would.

You want to check if a website loads correctly.

You want to test if clicking a button works.

You want to fill a form and submit it automatically.

You want to check if a page shows the right text after an action.

Syntax

Selenium Python

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

# Start browser
driver = webdriver.Chrome()

# Open a website
driver.get('https://example.com')

# Find an element
element = driver.find_element(By.TAG_NAME, 'h1')

# Check text
assert element.text == 'Example Domain'

# Close browser
driver.quit()

Use webdriver.Chrome() to open Chrome browser.

Use By to find elements safely and clearly.

Examples

Open Firefox browser instead of Chrome.

Selenium Python

driver = webdriver.Firefox()
driver.get('https://example.com')

Find a button by its unique ID.

Selenium Python

element = driver.find_element(By.ID, 'submit-button')

Check if the page title contains 'Welcome'.

Selenium Python

assert 'Welcome' in driver.title

Sample Program

This script opens Chrome, goes to example.com, finds the main heading, checks its text, prints a success message, and closes the browser.

Selenium Python

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

# Open Chrome browser
driver = webdriver.Chrome()

# Go to example.com
driver.get('https://example.com')

# Find the main heading
heading = driver.find_element(By.TAG_NAME, 'h1')

# Check the heading text
assert heading.text == 'Example Domain'

print('Test passed: Heading text is correct.')

# Close the browser
driver.quit()

Important Notes

Make sure you have the correct browser driver installed (like chromedriver for Chrome).

Always close the browser with driver.quit() to free resources.

Use clear locators like By.ID or By.TAG_NAME for reliable tests.

Summary

Selenium scripts control browsers to test websites automatically.

Start with opening a browser, visiting a page, finding elements, checking text, and closing the browser.

Use assertions to confirm the website behaves as expected.
