What is Selenium Headless and how do I use it?

Selenium Headless is a mode of Selenium that allows you to run tests without a graphical user interface. It’s useful for automated testing.

Can you give me an example of how to set it up?

Sure! You can set it up by using the following code snippet in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.headless = True

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

What are the advantages of using headless mode?

The advantages include faster execution, reduced resource consumption, and the ability to run tests on servers without a GUI.

Are there any limitations I should be aware of?

Yes, some limitations include potential differences in rendering and the inability to interact with certain UI elements that require a display.
