Selenium Architecture: Here, we will learn about the overall selenium architecture. How communication happens from client library to browser and which are all the components involved between them. Architecture compromises of major four components namely Selenium Language Binding JSON Wire Protocol Browser Drivers Real Browsers 1. Selenium Language Binding: Various programming languages provide their own Rest API support for communicating to their respective browser drivers via JSON Wire protocol. python provides 'selenium ' as a client library which has all the rest API i mplementation  for communicating with browser drivers.

It has got record playback and saving tests and inbuilt reporting tool.  2. Selenium Remote Control: Selenium RC was the flagship testing framework of the whole Selenium project for a long time. This is the first automated web testing tool where it allows users to use their programming language they prefer.
