# IMPORTANT NOTE:

#     `trace.hpp` will throw a linker error because we don't have access to
#     phosphor-logging in test ... yet.
#   - Some functions related to pdbg and dbus simply cannot be built in the test
#     environment. Instead, there are alternate implementation of those
#     functions to simulate them for testing.
