What is Python Selenium Architecture?
Selenium is a tool used to automate web browsers, and when we use it with Python, it becomes very simple and powerful. Python Selenium architecture is the way different parts work together to control the browser and perform actions like clicking buttons, entering text, or opening websites.
Here’s how it works:
First, you write your automation script using Python. This script includes commands like opening a browser, searching something on Google, or logging into a website.
These Python commands are sent to something called WebDriver. WebDriver is a middleman that connects your Python code to the actual web browser.
WebDriver then sends those commands to the browser-specific driver like ChromeDriver for Chrome or GeckoDriver for Firefox.
That driver talks to the real browser and performs the actions — just like a human would.
For example, if you write driver.get("https://google.com"), the WebDriver will open Google in the browser for you.
This setup helps in testing websites automatically without manual effort. Selenium also supports extra features like waiting for elements to load, handling alerts, clicking buttons, scrolling, etc.
Why Python Virtual Environment is Important?
Python Virtual Environment (venv) is a tool that creates a separate environment for each of your Python projects. It helps to keep things clean and avoid conflicts between different libraries or versions.
Let’s say you have two projects. One project needs an old version of Selenium, and the other needs a new one. If you install everything in your main system Python, it can get mixed up. But if you create a virtual environment for each project, each one will have its own setup, and there won’t be any confusion.
Selenium with Python helps to automate web browsers for testing.
It follows a flow: Python code → WebDriver → Browser Driver → Browser.
Python Virtual Environment helps to keep each project separate, avoid version problems, and make your setup clean and professional.
