      Description



      Name: kbR10066 Date: 01/15/2003


      Suppose we have two coverage items with and w/o test scale:

      Item1: (no test scale -> 1 test)
      3 1 13 0

      Item2: (test scale size is 2 -> 2 tests)
      3 1 13 7 #1

      This means that a test (say, test0) has not covered item1,
      test1 has covered item2 and test2 has not covered item2.

      If we merge files containing these (corresponding) items:

      > java com.sun.tdk.jcov.MergerMain -scale item1.jcov item2.jcov

      Then the merged item will be:
      3 1 13 7 #3
      as if all tests (test0, test1 and test2) cover this item, which is
      incorrect. Correctly merged item would look like:
      3 1 13 7 #2
      (only test1 covers this item).
