Sourcing global variables in unit tests

Please is there any way to source a script defining global variables in unit test (%!test) and have these available in functions called within the test?

This works:

%! global dataDir = '/tmp';
%! func_using_global_dataDir();

But this does not work, dataDir is not available in func_using_global_dataDir():

%! source 'consts.m';
%! func_using_global_dataDir();

Where script consts.m contains
global dataDir = '/tmp';

Yet when consts.m is sourced from another script (in the main code, not the unit script %! section), the global vars defined in consts.m are available in the script as well as all functions called by the script.

Tested with Octave 4.2.2 in Linux.

Thanks a lot for any help or suggestion how to let a unit test source/load a script with global constants used in functions tested by that test. Otherwise the scope of unit tests would be severely limited as all global variables (constants) used in the tested functions would have to be redefined in the unit test.

With regards,
