# Navigate to the web page you want to test

driver.get(‘https://example.com’)

# Capture a screenshot of the entire page

percySnapshot(driver, ‘Homepage’)

# Perform actions (e.g., clicking buttons, filling out forms)

# Capture another screenshot after the actions

percySnapshot(driver, ‘Homepage with Actions’)

# Close the browser

driver.quit()

In this example, we navigate to the desired web page after initializing the Selenium WebDriver. Next, we take screenshots at various points in our test script using the percySnapshot function from the Percy library. For easy visual comparison, these screenshots are automatically uploaded to the Percy platform.
