PYTHON SELENIUM ARCHITECTURE

As we all know, Selenium is an automation tool used for web application testing, and Python is a programming language. Selenium scripts can be written using only programming languages; the most commonly used programming languages are Java and Python.Pyhton and Selenium work together to create automation scripts and code that are used for interactions with web browsers.

This python code sets up a selenium automation script to open a chrome browser and navigate to a specified URL.

"""
This script is a basic example of how to use Selenium with Python to automate web browser action like opening a web page
"""

# Importing the selenium webdriver module to automate web browser interactions.
from selenium import webdriver
#Importing chromedrivermanager to automatically download and manage the chrome driver binary.
from webdriver_manager.chrome import ChromeDriverManager
#Importing the service class from the chrome module of selenium.
from selenium.webdriver.chrome.service import Service


class jay:


    def __init__(self, url):
        self.url = url
        self.driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))


    def start(self):
        self.driver.maximize_window()
        self.driver.get(self.url)


# executing main function
if __name__ == "__main__":
    url = "https://www.hotstar.com/in/home?ref=%2Fin"
    jay = jay(url)
    jay.start()

PYTHON VIRTUAL ENVIRONMENTS

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 ENVIROMENT?

It is Isolated environment for testing
Folder structure for your unique projects
Python virtual environments are essential for maintaining clean and reproducible development environments, managing dependencies effectively, and avoiding common issues related to package management and compatibility.

WHY DO WE NEED A VIRTUAL ENVIROMENT?

Imagine a scenario where you are working on two web-based Python projects one of them uses TATAPOWER 4.9 and the other uses TATAPOWER 4.15 (check for the latest ECOPOWER versions and so on). In such situations, we need to create a virtual environment in Python that can be really useful to maintain the dependencies of both projects.

HOW IT'S 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
