These functions help you determine if you code is running in a particular testing content:
is_testing() is TRUE when run inside a test.
is_parallel() is TRUE if the test is run in parallel.
is_checking() is TRUE when the tests run as part of R CMD check
(i.e. by test_check()).
testing_package() gives name of the package being tested.
A common use of these functions is to compute a default value for a quiet
argument with is_testing() && !is_snapshotting(). In this case, you'll
want to avoid an run-time dependency on testthat, in which case you should
just copy the implementation of these functions in a utils.R or similar.
