public unowned string get_filename (FileType file_type, string path_segments)
Gets the pathname to a data file that is required for a test.
This is the same as build_filename with two differences. The first difference is that you must only use this function from within a testcase function. The second difference is that you need not free the return value — it will be automatically freed when the testcase finishes running.
It is safe to use this function from a thread inside of a testcase but you must ensure that all such uses occur before the main testcase function returns (ie: it is best to ensure that all threads have been joined).
