I don't think it is specific for testthat. R CMD check sets R_TESTS when it runs the tests, so the separate R process it starts can have some special startup options.
The problem happens if you start another R process from your R test, and then R_TESTS confuses this process. (I am not sure how exactly.) A lot of packages have to work around this: https://github.com/search?q=user%3Acran+R_TESTS&type=Code Most of these use testthat, but not all of them.
