Called by default from with_mock() to determine the environment where to update mocked functions. This function is exported to help troubleshooting.

get_mock_env(.parent = parent.frame())



the environment in which to evaluate the expressions, defaults to parent.frame(). Usually doesn't need to be changed.


This function works differently depending on testthat::is_testing().

Outside testthat, topenv(.parent) is returned. This was the default for mockr < 0.1.0 and works for many cases.

In testthat, asNamespace("<package>") for the tested package is returned. The tested package is determined via testthat::testing_package(). If this is empty (e.g. if a test_that() block is run in interactive mode), this function looks in the search path for packages loaded by pkgload::load_all().
