Yesterday afternoon workmates at Java group found a bug in our program when doing the whole system testing. We are so suprised why this bug can not
be found at the unit testing phase. For submit the product on schedule, yesterday we have to re-make the unit testing report and redo all unit experiments.
This morning I investigate the bug again. I found the reason of missing bug is the unit report lost some cases. In fact, many a case is not in the
report.
