How to Use Selenium with Python for Web Scraping and Testing

The internet is filled with valuable data, and automation has become essential for developers, testers, and data analysts. Selenium with Python is a powerful combination for web scraping and automated testing. Whether you want to extract data from websites or automate browser actions, this Selenium with Python Tutorial will guide you through the process.

In this Selenium tutorial, we’ll explore how to set up Selenium with Python, perform web scraping, and conduct automated testing. By the end, you’ll be equipped with the skills to automate repetitive web tasks and streamline testing workflows.

What is Selenium?

Selenium is an open-source automation tool primarily used for testing web applications. It allows you to control web browsers programmatically, enabling tasks like filling forms, clicking buttons, and navigating pages. Selenium supports multiple programming languages, but Python is one of the most popular choices due to its simplicity and rich ecosystem of libraries.

Why Use Selenium with Python?

1. Automation – Automate repetitive web tasks, such as form submissions and logins.
2. Web Scraping – Extract data from websites efficiently.
3. Cross-Browser Testing – Run tests on multiple browsers, including Chrome, Firefox, and Edge.
4. Headless Browsing – Perform actions without displaying the browser UI for faster execution.
5. Integration with Other Python Libraries – Use Selenium with BeautifulSoup, Pandas, or Scrapy for advanced data extraction.

Setting Up Selenium with Python

Before using Selenium, you need to install the necessary components.

Step 1: Install Selenium

Use the following command to install Selenium:

pip install selenium

Step 2: Download WebDriver

Selenium requires a browser-specific WebDriver to interact with web pages. Download the appropriate driver for your browser:

• Chrome
• Firefox

After downloading, place the driver in a known directory and update the system path.

Step 3: Launch a Browser

Here’s how you can open a webpage using Selenium:

from selenium import webdriver

driver = webdriver.Chrome()  # Initialize Chrome browser
driver.get("https://example.com")  # Open a website
print(driver.title)  # Print page title
driver.quit()  # Close browser

Web Scraping with Selenium

Unlike static HTML pages, some websites use JavaScript to load data dynamically. Selenium can interact with such pages, making it ideal for web scraping.

Example: Extracting Text from a Website

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

driver = webdriver.Chrome()
driver.get("https://example.com")

# Extracting page content
element = driver.find_element(By.TAG_NAME, "h1")
print(element.text)  # Print heading text

driver.quit()

Handling Dynamic Content

For pages that load content dynamically, use explicit waits to ensure elements are available before interacting with them.

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get("https://example.com")

# Wait for an element to load
element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "dynamicElement"))
)

print(element.text)
driver.quit()

Automated Testing with Selenium

Selenium is widely used for automated testing to ensure web applications function correctly.

Example: Login Test Automation

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

driver = webdriver.Chrome()
driver.get("https://example.com/login")

# Enter username and password
driver.find_element(By.NAME, "username").send_keys("testuser")
driver.find_element(By.NAME, "password").send_keys("password123" + Keys.RETURN)

# Verify login success
assert "Dashboard" in driver.title

driver.quit()

Running Headless Tests

To speed up tests, run Selenium in headless mode (without a visible browser window).

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("--headless")

driver = webdriver.Chrome(options=options)
driver.get("https://example.com")
print(driver.title)
driver.quit()
