[R-pkg-devel] R CMD Check: Tests running infinite
A lot of packages have to work around this: https://github.com/search?q=user%3Acran+R_TESTS&type=Code
I wonder if those are mostly there because of cut'n'paste behavior.
It's not something I've ever advocated; I didn't realise there were so many people unsetting it. (devtools does it for you)
Most of these use testthat, but not all of them.
My interest in this issue is because I haven't yet experienced this myself and I run lots and lots of package tests in future that utilizes the parallel package. In doFuture I do similar tests, which is on top of the foreach package. I don't use testthat and I also don't use doParallel in my testing.
The motivation for unsetting in in devtools is to avoid problems when you run R CMD check from inside another R CMD check. I think it affects some behaviour deep inside R, not just fancy quoting. Hadley
