I was thinking more of looking for unstated dependencies in code effectively used by the package, though indirectly. I guess it is only relevant if distributing shiny apps alongisde packages becomes common practice. I am not sure how trendy it is yet, but wouldn't be surprised to see it become increasingly frequent.

Your test function can test whatever interests you.  If you want to test
for dependencies, just do it.  You can see how R implements those tests
by looking in the tools package, and either use them directly, or modify
them to your needs.
