Se² vs. Se³

What's the Difference?

Se² and Se³ are both chemical compounds of selenium, but they differ in their molecular structures and properties. Se² is a diatomic molecule consisting of two selenium atoms bonded together, while Se³ is a polyatomic molecule consisting of three selenium atoms bonded together. Se² is typically more stable and less reactive than Se³, which is known for its higher reactivity and ability to form a wider range of compounds. Overall, Se² is more commonly found in nature and is used in various industrial applications, while Se³ is less common and primarily used in research and specialized chemical processes.

Further Detail


Selenium is a popular open-source tool for automating web browsers. It provides a suite of tools for web application testing across different platforms and browsers. Two commonly used versions of Selenium are Se² and Se³. In this article, we will compare the attributes of Se² and Se³ to help users understand the differences between the two versions.


Se² is compatible with Selenium WebDriver 2.x, while Se³ is compatible with Selenium WebDriver 3.x. This means that Se² may not work with newer versions of Selenium WebDriver, which could limit its functionality. On the other hand, Se³ is designed to work seamlessly with the latest versions of Selenium WebDriver, ensuring better compatibility and performance.


Se² offers a basic set of features for automating web browsers, including the ability to interact with web elements, perform actions like clicking and typing, and navigate through web pages. Se³, on the other hand, comes with advanced features such as the ability to run tests in parallel, take screenshots during test execution, and integrate with third-party tools for reporting and monitoring.


When it comes to performance, Se³ outshines Se² due to its improved architecture and optimized codebase. Se³ is faster and more reliable than Se², making it a preferred choice for users who prioritize speed and efficiency in their test automation projects. Additionally, Se³ offers better support for modern web technologies, ensuring smoother test execution across different browsers and platforms.

Community Support

Both Se² and Se³ have active communities of users and developers who contribute to the projects and provide support to fellow users. However, Se³ has a larger and more vibrant community compared to Se², which means that users are more likely to find help and resources for Se³. The larger community also leads to more frequent updates and enhancements for Se³, ensuring that users have access to the latest features and improvements.


Documentation is crucial for users to understand how to use Selenium effectively. Se² and Se³ both have comprehensive documentation that covers the basics of test automation with Selenium, as well as advanced topics like handling dynamic web elements and working with different browsers. However, Se³'s documentation is more up-to-date and detailed compared to Se², making it easier for users to find answers to their questions and troubleshoot issues.


In conclusion, Se² and Se³ are both powerful tools for automating web browsers, but they have distinct attributes that set them apart. Se² is a reliable choice for users who are comfortable with older versions of Selenium WebDriver and do not require advanced features. On the other hand, Se³ is a more modern and feature-rich option that offers better performance, compatibility, and community support. Ultimately, the choice between Se² and Se³ depends on the specific needs and preferences of the user.
