# Certain tests written as unit tests of fuchsia-zircon make use of other
# crates which themselves depend on fuchsia-zircon. This causes
# fuchsia_zircon::foo to be a different type from crate::foo in the context of
# those unit tests when fuchsia-zircon is built with `with_unit_tests = true`.
#
# Since those tests are really integration tests, we should either move them
# into the "other" crates so that the dependency graph flows in only one
# direction, or simply move those tests into a dedicated target and redesignate
# them as integration tests, which they appear to be.
