1.Describe Selenium Architecture in detail?

Selenium

-->Selenium is an open-source framework used to automate the testing of web applications

--> Selenium is an automation tool used for web application testing, and Python is a programming language.

Python Selenium Architecture

The Python Selenium architecture consists of several components that work together to enable the automation of web browsers. Below is a detailed description of the key elements in the Python Selenium architecture

Components of Selenium Suite

Selenium IDE

--> It is a plugin developed for web-browsers like Firefox, Chrome and Edge.
--> It helps the testers and developers to record and playback the test-scripts.
--> It is used for prototyping test-cases before you write any --> real automation testing test-cases.

Selenium WebDriver

--> It is an API which helps us to run our test-cases on the browsers by manipulating the JavScript DOM.
--> It acts as a bridge between Python Selenium framework and web-browser.
--> The current version is version-4
--> Selenium Remote Control
--> It is an outdated version removed from Selenium suite
--> It has been replaced by Selenium WebDriver
Not used today.

Selenium Grid

--> To run parallel tests on multiple machines situated at multiple locations you can use the Selenium Grid

Python Virtual Environment

Python Virtual environment is an self-contained isolated directory which contains Python and its various modules.

It is used for sand-boking different modules of Python and to test it.

Why we use Python Virtual Environment

--> It is Isolated environment for testing
--> Folder structure for your unique projects

*How it works *

--> Creating an environment

--> pip install virtualenv
--> Activating the virtual environment
--> virtual env
--> Scripts\activate
--> Install the required package modules using PIP command
--> deactivate the virtual environment
--> Scripts\deactivate
