Determine testing status

Source: R/test-env.R
is_testing.Rd

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.

Usage

is_testing()

is_parallel()

is_checking()
