DOMContentLoaded

This test checks when the webpage is fully loaded, meaning all content is ready, including the ad.

Why do we test it?

Ensuring the ad loads after the webpage helps provide a smooth experience for users. If the ad loads too early, it might slow down the page, leading to frustration.
