TEST mode doesnt work with GPS?

I'm following This Tutorial and I'm intrigued! It says:
To try this app, download the app backup and create a new app from it. Keep in mind that you do need to build a binary file and install it on the device for testing.

I can't test the app if a GPS is used? Why is that?
