Managing browser drivers like ChromeDriver or GeckoDriver in Selenium with Python is essential to automate web browsers. These drivers act as a bridge between Selenium and the browser. Traditionally, managing them involved downloading the correct driver version manually and setting its path, but now it's easier and more efficient using tools like webdriver-manager.

1. Manual Setup (Less Preferred):

You must:

  • Download the correct driver version from the browser’s official site.

  • Set the system path or specify the path in your script.

2. Automated Setup with webdriver-manager (Recommended):

This Python package automatically downloads and manages the correct driver versions for you.

Installation:

This approach:

  • Ensures compatibility with the installed browser version

  • Reduces errors due to version mismatches

  • Simplifies code and CI/CD integration

You can use similar managers for other browsers:

  • Gecko Driver Manager for Firefox

  • Edge Chromium Driver Manager for Edge

Best Practices:

  • Always use a driver manager in dynamic environments (like Docker or CI/CD).

  • Keep drivers updated to match browser updates.
