What is Selenium WebDriver and how do I use it for integration testing?

Selenium WebDriver is a tool for automating web applications for testing purposes. It allows you to write tests in various programming languages and interact with web elements.

Can you give me an example of a simple integration test using Selenium?

Sure! Here's a simple example in Python:

from selenium import webdriver

# Set up the WebDriver
driver = webdriver.Chrome()

# Navigate to the application
driver.get('http://example.com')

# Find an element and perform an action
button = driver.find_element_by_id('submit')
button.click()

# Verify the result
assert 'Success' in driver.page_source

# Close the browser
driver.quit()

What are some best practices for writing Selenium tests?

Some best practices include:

1. Keep tests independent.
2. Use explicit waits instead of implicit waits.
3. Organize tests into suites.
4. Use page object models for better maintainability.
