In this case, the output reports Completed without error. Also notice from the additional entry in the output that the test has been run previously.

Listings 8 and 9 show running the long, or extended, offline test and viewing its output. Remember, the command just kicks off the test; the long test might take several minutes to complete. To check whether the test has completed, use the same -l selftest option as before.
