Comment (by MrSquanchee):

 Hii, asn.
 1. `rep_hist_bw_stats_write()` gets called from
 `write_stats_file_callback` in mainloop.c.
  This function handles disk write for all the stats produced.
  So, do you want exhaustive unit-tests for `write_stats_file_callback`,
 which would test
  for all the stats ?? or should I write unit tests for
 `write_stats_file_callback`
  pertaining only to the bandwidth statistics ??
 2. Also, `rep_hist_bw_stats_write()` writes the stats to the disk, so does
 many other stat
  functions, but I haven't yet seen a unit test that tests for a directory
 and contents of
  a file maybe for some reasons I don't know or maybe I am wrong and you
 can point me to
  an appropriate test.
  Would you like to explain how I can write such a test  ??
