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