For every completed test in a collection, DTM performs
  the following steps:

  1. Compares the result file to the benchmark file, if
     any

  2. Saves the comparison status for the test

  3. Saves any differences in a difference file

  4. Deletes the result file if it matches the benchmark

  DTM will not automatically complete the comparison
  process if any of the following conditions exist:

  o  You chose the option not to compare when you created
     the collection

  o  A test in the collection is only partially run

  o  Some of the tests in the collection do not run

  In each of these cases, you need to manually initiate
  the comparison of test results before you can review
  the results.

1  –  man_compare

  To manually compare test results, perform the following
  steps:

  1. Pull down the Testing menu.

  2. Choose the Compare... menu item.

  The Compare dialog box enables you to choose the type
  of test comparison, the differences format, and special
  characters that DTM should ignore during a comparison.

2  –  compare_status

  DTM reports one of the following comparison states for
  a test in a view window:

                 comparison for a collection
