Understanding the Importance of Language Verification in Selenium Tests

When working with Selenium for web automation and testing, a common requirement arises: verifying that the content of the website is displayed in the correct language. This becomes particularly crucial when localizing web applications for international users. In this guide, we will dive into a specific question: How to get the language of a website in Selenium using Python?

Setting Up Language in Selenium

Here’s how you can retrieve the language attribute from a webpage using Selenium and Python. Follow these steps to ensure you are getting the correct language settings:

Step 1: Import Required Libraries

First, make sure you have the necessary libraries installed and imported. Most notably, you will need selenium and its webdriver.
