How do I make a Mac App Store app that validates receipts?

I've made an app that validates its receipt using the ValidateStoreReceipt code on GitHub according to the Apple documentation. The docs say to sign your app, make a package (with signing), and then install it via command line. Then run the app, see there is no receipt, return code 173, and it'll prompt you for a test account login (which it does). I supply the test account (from setting up a test user on iTunesConnect). Then, nothing happens. It should then download a receipt into the app bundle and relaunch the application, but it does neither. The Console says only this:

My post build script looks like this:

codesign -f -s "3rd Party Mac Developer Application: MYCOMPANYNAME" -v build/Release/AppStoreTest.app    
cd build/Release
productbuild --component AppStoreTest.app /Applications --sign "3rd Party Mac Developer Installer: MYCOMPANYNAME"  AppStoreTest.pkg

Am I doing something wrong??

I think I found the answer! It looks like you have to actually set up your whole app on itunesconnect, all the way up to the point where you're going to upload it, before it'll work. Just having the bundle ID is not enough; it has to be pending upload. Just thought I'd throw that out there in case anybody else runs into this.
