Sourcing global variables in unit tests

[Pavel Hofman]

Hi,

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:

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

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


%!test
%! 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,

Pavel.
