test_cross_browser_compatibility()This script tests the website https://example.com on three browsers: Chrome, Firefox, and Edge.
We use webdriver_manager to automatically download and manage browser drivers, so no manual setup is needed.
For each browser, the script:
- Starts the browser
- Navigates to the URL
- Waits explicitly until the page title matches the expected title
- Asserts the page title is exactly 'Example Domain'
- Closes the browser to free resources
This ensures the website works correctly on all three browsers, demonstrating cross-browser compatibility.
Using explicit waits avoids flaky tests by waiting for the page to load fully before checking the title.
Try-finally ensures browsers close even if assertions fail, preventing leftover browser processes.
