Rules Engine is a library/NuGet package for abstracting business logic/rules/policies out of a system. It provides a simple way of giving you the ability to put your rules in a store outside the core logic of the system, thus ensuring that any change in rules don't affect the core system.
Selenium is a set of different software tools each with a different approach to supporting browser automation. These tools are highly flexible, allowing many options for locating and manipulating elements within a browser, and one of its key features is the support for automating multiple browser platforms. This package contains the .NET bindings for the concise and object-based Selenium WebDriver API, which uses native OS-level events to manipulate the browser, bypassing the JavaScript sandbox, and does not require the Selenium Server to automate the browser.
