Wrong question.
Better question: Should the test be running? My preference is for only
inside of a requireNamespace() (or equivalent) block as the package is
not
guaranteed to be present. In theory.
In practice people seem to unconditionally install it anyway, and
think that
is a good idea. I disagree on both counts but remain in the vocal
minority.
As another package maintainer, I had almost the identical question
reading the previous (long) thread, but the three answers here don't
give the same answer. My question I can make even more concrete:
I use the testthat package for my testing. I never use it in the R code
itself, and it is explicitly only used for testing. Should that be
included as "Depends" because every test requires it or "Suggests"
because no end user ever needs it?
If "Depends", then it leads to over-installation of the package by end
users who don't care about running tests locally. If "Suggests", then
all of the tests would fail (assuming that Dirk's suggestion is
implemented).
Suggests.

At a loss,
