In order to both maintain control of test env data, as
well as ensure open-source users are able to run the
integration tests on personal account data, the test
user must be derived from the test configuration, rather
than hardcoded within the tests.
The alias of testing to ctesting prevented auto-importing
of the testing library. This change (arbitrarily) renames
the package so that it doesn't collide with the core pkg
for "testing".
