-#' * `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`

+#' * `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.
