| How is testthat related to this? When you `R CMD INSTALL` a package,

I presume you know the other per the bottom part of the email. Following the
(very early best practive started by P Grosjean, M Maechler and others)
tests/doRUnit.R always calls out to files in inst/tests or inst/unitTests.

Which. Get. Installed.

For every user. Automatically.  A much better default.

You probably need a) the required env var set and b) the RUnit test runner to
loop over RUnit tests and c) make sure the dependent C++ files are compiled
first which is why we have a wrapper in that package.  But note that I never
claimed it currently worked -- that test setup (being able to run from tests/
and once installed) is more tricky for Rcpp due to the compilation.

I did claim that by not giving the testthat user that option you are not helping.
And I stand by that.
