Hmmm, all the suggested options are quite difficult to implement.
I'm quite sure they wouldn't be bothered to create one themselves,
lest they would have done so and not reject our app outright.
Is it not possible for the AdSense team to create test accounts for
such scenarios?
Perhaps one single account that everyone can use (read only) when
developing their app?
I'm pretty sure a lot of developers would find this helpful.
Thanks.
