Unset R_TESTS

[gaborcsardi]

It only causes trouble, it is not actually doing anything useful.

Always, or just in test_check()?

[gaborcsardi]

why not always? to have consistent behavior?.

[hadley]

Ok, sure thing.

Will this affect #86? I am preparing drake for the upcoming testthat 2.0.0, and I rely on tests executed in subdirectories of tempdir().

[gaborcsardi]

Yes, it fixes #86.

[wlandau-lilly]

Perfect!

I used to use the presence of R_TESTS to skip certain tests which don't play well with R CMD check. Is there an alternative? I'm aware of skip_on_cran and friends.

[gaborcsardi]

@hughjonesd you can set an environment variable in tests/testthat.R. This only runs for R CMD check.

Got it. Thank you.
