I'm not sure if there is a best practice for this, but I make a test like this:
add_test(package ${CMAKE_CPACK_COMMAND} -V -C \${CTEST_CONFIGURATION_TYPE} --config "${CMAKE_BINARY_DIR}/CPackConfig.cmake")

With it being verbose (-V), I can get extra information to show up on cdash in case there are problems.

I also have additional install commands
install(CODE/SCRIPT ...)
to check if the installation is OK.  That includes things like BundleUtilities, and a test run of the program.
