Console Errors

This test looks for errors in the JavaScript code used by the ad tag.

Why do we test it?

JavaScript errors can prevent the ad from displaying correctly or from tracking impressions and clicks. Validating that the ad is free of errors ensures it functions as expected across all browsers.
