How do you set up GeckoDriver for Firefox in Selenium with Python?

Download the GeckoDriver executable, place it in a known folder, and specify its path in your Selenium script using: <br><code>from selenium.webdriver.firefox.service import Service<br>from selenium import webdriver<br>driver = webdriver.Firefox(service=Service(executable_path='path/to/geckodriver'))</code>

Why is it important to match the WebDriver version with the browser version?

Because WebDriver controls the browser, if their versions don't match, commands may fail or behave unexpectedly. Matching versions ensures smooth communication and reliable test execution.

What is the role of the PATH environment variable in WebDriver setup?

Adding the WebDriver executable (like chromedriver.exe) to the PATH lets Selenium find it automatically without specifying the full path in code, making setup easier and cleaner.

Show a simple Python code snippet to start Chrome browser using ChromeDriver in Selenium.

from selenium import webdriver

# Assuming chromedriver is in PATH
driver = webdriver.Chrome()
driver.get('https://example.com')
driver.quit()

This opens Chrome, goes to example.com, then closes the browser.

What must you do before using ChromeDriver in Selenium tests?

A Download ChromeDriver and ensure it matches your Chrome browser version

B Install Firefox browser

C Write tests in JavaScript

D Disable browser security settings

You need to download ChromeDriver and make sure its version matches your Chrome browser for Selenium to control it properly.

Which WebDriver is used to automate Firefox browser?

A EdgeDriver

B GeckoDriver

C ChromeDriver

D SafariDriver

GeckoDriver is the WebDriver used to automate Firefox browser.

How can Selenium find the WebDriver executable without specifying its full path in code?

A By installing Selenium globally

B By using a special Selenium command

C By adding the WebDriver to the system PATH environment variable

D By renaming the WebDriver file

Adding the WebDriver executable to the PATH environment variable allows Selenium to find it automatically.

What happens if the WebDriver version does not match the browser version?

A Tests run faster

B Browser updates automatically

C No effect on tests

D Selenium commands may fail or behave unexpectedly

Mismatch between WebDriver and browser versions can cause Selenium commands to fail or behave incorrectly.

Which Python import is needed to use WebDriver for Chrome?

A from selenium import webdriver

B from selenium.webdriver.chrome import ChromeDriver

C import chromedriver

D import requests

You import webdriver from selenium to use ChromeDriver in Python.

Explain the steps to set up ChromeDriver for Selenium testing in Python.

Think about downloading, version matching, environment setup, and code usage.

Why is it important to keep WebDriver and browser versions compatible?

Consider how communication between WebDriver and browser works.
