  30 /* Tests to see if the routine to read a secondary lease file
  31  * for the DUID works properly.  The tests:
  32  * Test file x:
  33  * no test file - should result in no duid
  34  * Test filx 0:
  35  * A test file but no DUID def, no duid
  36  * Test file 1:
  37  * Can it read a single DUID in the file?
  38  * Test file 2:
  39  * Can it find a second DUID in the file after a good lease and
  40  * a badly formatted lease?
  41  * Test file 3:
  42  * Can it find a later DUID after a good one and a bad one?
  43  * and to give a bit more coverage test file 1 should use LLT
  44  * test file 2 should use LL and test file 3 should use LL for
  45  * the first one and LLT for the third one.
