Index File Check

This checks if the ZIP package contains an index.html file, the default entry point for most HTML5 ads.

Why do we test it?

Having an index.html file is critical, as ad servers expect it to serve as the starting point for rendering the ad. If missing, the ad might not render properly, leading to campaign failures or rejected placements.
