It depends. If F and G are both public functions that are part of 
the API, then one can't. Otherwise I'd just test F since G is an 
implementation detail.

I consider keeping tests around for implementation details an 
anti-pattern. Sometimes it's useful to write the tests if doing 
TDD or debugging, but afterwards I delete them.
