What is the difference between Selenium and Zelenium?

Selenium is a set of tools for automating web application testing, including WebDriver API, Selenium IDE, and Selenium Grid. It allows interaction with browsers directly through their native mechanisms or drivers.

Zelenium is a fork (development branch) of Selenium, based on Selenium RC (an outdated component of Selenium). It is mainly known for its ability to take screenshots and compare them for visual testing.

Main differences:

• Purpose: Selenium is a standardized tool for browser automation. Zelenium is an extension of Selenium RC, focused on screenshots and visual regression testing.
• Relevance: Selenium is actively supported and developed (WebDriver is the modern standard). Zelenium is based on outdated technology (Selenium RC) and is not a current solution for new projects.
• Architecture: Selenium WebDriver interacts directly with the browser. Zelenium used a proxy server approach (Selenium RC).
• Functionality: Selenium offers a wide range of capabilities for interacting with elements, navigation, and executing JavaScript. Zelenium added features for capturing and comparing screenshots.
