It is actually often not trivial at all. E.g. if you have a test with
setup/teardown, and the setup must be run before each test case, the
teardown after, and you want to run each test case in a clean
environment, this really does not play well with source-ing files.

It is definitely possible, and probably works for smaller packages
with simple tests, but imo it is not good practice.

Yes, it is trivial, but I think this is not good practice either. E.g.
testthat gives you a summary in the end, and then you would need to
look at multiple summaries. It is easy to forget about the multiple
summaries, and miss one.

I think it is way easier if you just invoke the testing once, and let
it select what to run based on where it is running, what services are
available, etc.
