There is also a way to write C++ unit test with the catch framework and have them added to the R test suite: https://rdrr.io/cran/testthat/man/use_catch.html
Note this was originally built with integration with testthat in mind but you can call it from any R test suite (docs on doing this are on the linked to page).
