I ran into some interesting limitations when trying to test a friend's trip tracking application.

I can record a sequence of events that includes just about anything the phone can do: lat/long changes, speed, orientation, changes in motion state (idle, walking, driving, etc), geofencing, bluetooth state changes, wifi state changes, etc. Everything timestamped.

But, how do you play this sequence back in a way that makes the app think you're taking the same trip again? I was hoping the OS (iOS and/or Android) would provide a mechanism for this. And it does, but only lat/long. Nothing else.

The missing information is very important when trying to debug what's going on in my application on any particular trip. Now, I know I can create my own version of CLLocation that will generate these events whenever I want them, but I was hoping to find a solution that didn't require changing application code to support. I would like to take my findings and create a product that can help people do this sort of testing and requiring them to switch out CLLocation everywhere it's used in their application is a difficult sell.
