On line 277 of https://github.com/arrayfire/arrayfire/blob/bdda3b3ea454030099871319c724eec4ee205bed/test/CMakeLists.txt I see the following:

# TODO(umar): Create this executable separately
if(NOT ${backend} STREQUAL "unified" OR ${target} STREQUAL "backend_unified")
  af_add_test(${target} ${backend} ${mt_args_SERIAL})
endif()

If I comment out if and endif then the unified tests are run with ctest
