Something like this may do:

Iterate over the package names in package.loaded.  Convert each
package name to a file name by consulting the package.path variable in
the same manner that require does so.  (For an idea of how you might
do this see http://lua-users.org/wiki/BinaryModulesLoader or
http://www.keplerproject.org/compat/ .)  Storing the inverse mapping
of this in a table allows you to determine package names(s) that map
to a given file name.

Then iterate over the table of file names.  For each file name,
convert it into a package name by consulting the map above.  Do
require(package_name) (note: calling require twice has no side-effect)
and store the return value, which is the package table.  Call the
test_function() inside it or, to find MODULENAME (which might differ
from the package name passed to require), lookup inside package.loaded
for a MODULENAME having a package table matching this package table.
