Provide a predicate for skipping tests when running via test_local().

[krivit]

One of my packages (https://github.com/statnet/ergm) uses R's documentation system in some unusual ways, and a consequence of this is that some tests that pass on CRAN or locally when invoked via test_check() fail when run via test_local(). Is there a way to configure the tests to skip if invoked via test_local()?

Unfortunately this feels very esoteric to me; I'd suggest figuring out another way to do skipping.

Replying here in case someone else has a similar problem.

testthat has a predicate is_checking() that returns TRUE if the code is being run through test_check() and FALSE otherwise, so skip_if_not(is_checking()) should skip the tests when run interactively.
