Selenium

Selenium is an open-source automation tool used primarily for testing web applications. It allows developers to simulate user interactions with a website, such as clicking buttons, filling out forms, or navigating through pages. Selenium supports multiple programming languages, including Python, Java, and C#, and can be used across different browsers like Chrome, Firefox, and Safari.

We typically use Selenium when we need to automate web browsers for tasks like:

• Web Scraping Dynamic Content: Scraping data from websites that rely on JavaScript for rendering content, where traditional scraping tools like Beautiful Soup or Scrapy might fail to capture the necessary information.
• Testing Web Applications: Automating functional testing to ensure web applications work as expected across different browsers and environments.
• Automating Repetitive Web Tasks: Automating routine tasks such as logging into accounts, downloading files, or filling out forms that require interaction with web elements.

Selenium is especially useful when dealing with websites that require user interactions or contain dynamically loaded content.
