Do not use google_adtest in your ads
Very often I edit and test my website files locally. But when I open locally page with ads, it generates impressions. That’s not allowed by the Google Adsense TOS.
You may search on the web about how to test ads without generating impressions and you’ll find that adding google_adtest=”on” in your ads will let you load ads without worry about impressions. The problem is that the info that suggest using google_adtest is too old.
The truth seems to be that this feature is no longer available. I found that in Google Support Forum HERE.
Also, google_adtest cannot be found in the Adsense Documentation.
I prevent not to take risks with using google_adtest attribute, that’s why when I test my website locally I use Server Side Comment.
