[R-pkg-devel] Skipping tests on CRAN

[Mark van der Loo]

Hi Ott,

There is no documented way to detect whether you are running on CRAN. So
there is nothing to rely on, on that side.

You can only make your own machine detectable by the test code. For example
by setting an environment variable that identifies your machine and make
test execution depend on the value of that environment variable. This is
what tinytest does under the hood.

Best,
Mark
