How to use "Google AdSense" in test mode

Although it is common to try to create a test environment before running a blog or web service, I think that there are times when I'm at a loss as to whether AdSense can be pasted in that test environment. The reason is mainly because if you accidentally click on yourself, it will be a very bad thing.

It is unknown whether it is for such a case, but the test mode of "Google AdSense" is mainly used overseas. As long as I use it, I do not count it even if I click it.

Details are as follows.

Easy to use, first add the following line to the generated code.

Google_adtest = "on";

Finally change "google_ad_client" as follows.

Google_ad_client = "ca-test";

It seems that it becomes a code of the test mode which does not count even if clicked. However, in the contract, it is supposed not to modify the generated code, but I do not quite understand what will happen around that ... ....
