In a way , I think Mathematica obliges the developer to use more foolproof
programming.
This is what I mean:
Your symbol x is a special (default) value for a function (foo) that
only makes sense if you load testpackage. So very likely also x makes
sense only if you load testpackage (and perhaps some other accessory
package).
So x shouldn't be a Global symbol anyway (in most likely situations).
In other words: x , like foo, should be defined in testpackage.
So add

x::usage=.....

But if x is defined in some other AuxPackage or is really something
very general whch is defined in the Global context, then include this
other package or the Global context in the context path, using the
approrpiate BeginPackage[.....] declaration. Something like:

BeginPackage["context`",{"Global`","AuxPackage`",...}]
