Selenium Webdriver architectural diagram

In this post, you will get to know the Selenium Webdriver architectural diagram.
Before you take a look at diagram, kindly note below points.

  1. Selenium webdriver uses JSON WIRE protocol over well known HTTP protocol.
  2. Your automation code sends HTTP commands to Webdriver Server (IEDriverServer.exe or ChromeDriver.exe).
  3.  Webdriver Server (IEDriverServer.exe or ChromeDriver.exe) sends these commands to the browser under test through HTTP proxy.
  4. Browser under test executes the commands sent by Webdriver Server and sends the results back to the Webdriver Server.
  5. Webdriver server interprets the results and your automation code takes further action on those results.
