-class TestDifflibLongestMatch(unittest.TestCase):
-    # From Patch #1678339:
-    # The find_longest_match method in the difflib's SequenceMatcher has a bug.
-
-    # The bug is in turn caused by a problem with creating a b2j mapping which
-    # should contain a list of indices for each of the list elements in b.
-    # However, when the b2j mapping is being created (this is being done in
-    # __chain_b method in the SequenceMatcher) the mapping becomes broken. The
-    # cause of this is that for the frequently used elements the list of indices
-    # is removed and the element is being enlisted in the populardict mapping.
-
-    # The test case tries to match two strings like:
-    # abbbbbb.... and ...bbbbbbc
-
-    # The number of b is equal and the find_longest_match should have returned
-    # the proper amount. However, in case the number of "b"s is large enough, the
-    # method reports that the length of the longest common substring is 0. It
-    # simply can't find it.
-
-    # A bug was raised some time ago on this matter. It's ID is 1528074.
