Browser Drivers – In order to run Selenium scripts on a particular browser, we need to pass the command to the respective browser.

JSON Wire Protocol over HTTP – The JSON or JavaScript Object Notation protocol wire protocol provides the capability of transferring data between the client and server over the internet.Selenium Client – Selenium Client Library or the language bindings allows us to write the Selenium automation scripts in the language of our choice – Java, Python, C#, Ruby, Javascript, etc.The Selenium WebDriver architecture comprises of four components. In order to understand the working of web UI automation on different browsers using Selenium, we need to understand its architecture. Python is an interpreted language that makes debugging of Python code very easy.It also has a very active and large community support backed by companies like Google, Facebook, and Amazon. There are various open-source Python libraries and frameworks available.Also, allows running the same code on different platforms without the need for re-compilation. The code written in Python is considered much faster and reliable as compared to most of the modern programming languages.Due to this, it is easy to write and maintain Python code. It is easy to learn and has fairly readable code.It is one of the fastest-growing programming languages in the world right now. Python is a high-level, interpreted, object-oriented programming language.

So, we can safely exclude it from this Selenium WebDriver with Python tutorial. There is one more component of Selenium – Selenium RC (Remote Control).

Selenium Grid – Selenium Grid is the Selenium component that is used to run Selenium tests in parallel across different browsers and operating systems.

It interacts with the different browsers using browser drivers like – ChromeDriver, FirefoxDriver, InternetExplorerDriver, SafariDriver, etc.

Selenium WebDriver – This is the most widely used component of Selenium.

But using this we can not create a full-fledged test automation suite. Using this we can quickly automate a simple workflow.

Selenium IDE – It is a record and playback tool.

Out of which both Java and Python are widely used and have the major market share.

For example – Python, Java, Ruby, C#, JavaScript, etc. It supports all the widely used programming languages.Can work seamlessly with all the popular platforms – Windows, Linux, Mac. Some of these are – Chrome, Firefox, Internet Explorer, Microsoft Edge, Safari, Opera, etc.
