Try to access the page on a slow network. Get a bad broadband connection with slow internet speed and load the page. It'll take some time to load the page and in the mean while if the page loader displays have celebrations with your team otherwise report a bug.
You can also try connecting your mobile data to your laptop via hotspot or even via Bluetooth (if you have a Bluetooth enabled laptop or a dongle for it). That might help you with a slow net speed. You can call the customer care of your mobile carrier for settings to share your mobile internet with your laptop.
Here are some points to consider when testing waiting/progress indicators:
- Verify that the indicator displays when the page is loading and disappears once the page has finished loading.
- Test the indicator on different browsers and devices to ensure it is visible and functional across all platforms.
- Test the indicator with slow or unreliable internet connections to verify that it displays appropriately during extended loading times.
- Verify that the indicator does not block or interfere with user interaction with the page.
- Test the indicator in different scenarios, such as during AJAX calls or when submitting a form, to ensure it displays and behaves as expected.
- Verify that the indicator is not displayed unnecessarily, such as when navigating between pages on the same site or when interacting with elements that do not require loading.
- Test the indicator with different types of content, such as images, videos, and complex HTML, to ensure it displays appropriately during longer loading times.
