-
-`default-can-be-prefix-*.cpp` verifies the effect of `Interest::setDefaultCanBePrefix`.
-They are written as integration tests because ndn-cxx unit tests are prohibited from calling `Interest::setDefaultCanBePrefix`.
-
-Manual verification steps:
-
-1. `default-can-be-prefix-unset` program should print a "CanBePrefix unset" warning to stderr.
-2. `default-can-be-prefix-0` and `default-can-be-prefix-1` test cases should not print that warning.
