I also want to know how!

I had the same situation and solved by the following hack.

In my case, the test files are located at $(TOP)/asset, where $(TOP) is 
defined in Jamroot:

path-constant TOP : . ;

The basic idea is to pass the location of the test file by preprocessor 
definition ( <define> property).

Here is the Jamfile for the unit test. 

# $(TOP) may use '\' as a path separeter, which we cannot pass
# as <define> value. So, modify it to use '/' instead of '\'.
local path_tokens = [ regex.split $(TOP)/asset "[/\\]" ] ;
local normalized_path = [ path.join $(path_tokens) ] ;

unit-test test : 
test.cpp
/prebuilt/boost//boost_unit_test_framework
: <define>PATH_TEST_FOOTAGE=$(normalized_path) 
;

In the test.cpp, we can refer the value of PATH_TEST_FOOTAGE by:

#define STRING(s) # s
#define XSTRING(s) STRING(s)

string testFilename = XSTRING(PATH_TEST_FOOTAGE) "/test.dat";

Hope it helps.
