App is in "Pending Developer Release" mode how do i test in app purchase and subscription?

hi all,

App is in "Pending Developer Release" mode how do i test in-app purchase and subscription?. my fear is that if it wont work than it would be a problem. in testflight i could test it with sandbox user but in pending developer release mode before release how could i test it? should i test it with testflight version submitted for release.? but in this tesflight version don't ask for real user in-app purchase thing. it shows same sandbox user and testing mode. my fear is if we release this pending developer release version app will it ask for money from our user?

how do i test and convince my business partners that it would ask real money for in app purchase when we release this pending developer release mode.i am new so dont know much i am in doubt too.

how do we access this pending developer release app before releasing to world and test it for payment related things and get confirmation to release. please help.
