That depends upon how you define unit tests. For purposes of unit
testing, I treat functions with internal linkage as part of the
function(s) with external linkage in the same translation unit that
(directly or indirectly) call them. If they have any feature which
cannot be properly tested through calls to those externally linked
functions, then that generally means that the feature is either
unnecessary or at least badly designed.

No, but it can dramatically increase that limit. Well-designed programs
stress your short-term memory capacity much less than poorly designed
programs, because they're easier to understand.
