And not only at the time of posting even if they are testing their site layout they reload their page many times. But the point is that Google don't know about this activity and they are unaware that you are updating your site and we know that AdSense team members continuously monitors their publisher's website and if they track this request for ads from the same IP address they can penalize you for 'click fraud'.
And sometimes while testing there is a possibility of accidental clicks on our own ads. So what should we do so that we can securely test our sites without affecting the ads. So here are some tips you can try.
• You can remove the ad codes from the page you are writing and after publishing the article you can put it.
• In place of original ads you can use static images of ads which you can get here.
• You can use Adblock Plus to stop showing ads on your site. It is an extension for Chrome and Firefox.
It is under the policy of AdSense that sites showing AdSense ads must not be under construction. You can use ads only after your site is complete and actively running.
