WHAT IS SELENIUM:

  • An open source automation testing frame work used primarily for testing web application.

  • Lets developers write tests in languages like java, python, java script.

  • Can simulate user action like clicking buttons, filling out forms, and navigating pages across different browsers ( chrome, firefox,etc).

  • Often used in CI/CD pipelines for automated testing.

USE SELENIUM FOR AUTOMATION

:

  1. CROSS BROWSER TESTING

    Selenium supports all major browsers: chrome, firefox, edge, safari,etc..

  2. MULTI LANGUAGE SUPPORT

    You can write selenium scripts in several languages like python, java, c## ......

  3. Open source:

    it's free to use with a strong community and lots of plugins/extensions.

RELEVANCEOF SELENIUM IN AUTOMATION TESTING USING PYTHON:

SELENIUM IS HIGHLY RELEVANT IN AUTOMATION TESTING WITH PYTHON DUE TO SEVERAL KEY REASONS.

  1. BROWSER AUTOMATION:

Selenium allows you to control real web browsers 9like chrome, firefox, edge) programmatically. this is essential for testing how web apps behave in a real environment.

  1. END-TOEND TESTING:

With selenium you can simulate user interaction like:

  • Clicking buttons
  • Filling form
  • navigating pages
  • Uploading files this makes it ideal for end-to-end(E2E) and functional testing of web application.

3.** PYTHON INTEGRATON**

Python is a clean readable and powerful language. Selenium's Python bindings make it easy to:

  • Write concise and readable test scripts
  • Integrate with testing framework like Pytest or unittest
  • Generate test report or logs
  1. CROSS-BROWSER TESTING

You can run the same test across different browsers to ensure compatibility.
