is_testing {testthat}

Determine testing status

Description

These functions help you determine if you code is running in a particular testing context:

• is_testing() is TRUE inside a test.

• is_snapshot() is TRUE inside a snapshot test

• is_checking() is TRUE inside of ⁠R CMD check⁠ (i.e. by test_check()).

• is_parallel() is TRUE if the tests are run in parallel.

• 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_snapshot(). 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 into a utils.R or similar.
