When a test suite runs in the background and appends to a log, grepping the log for the summary line or counting PASS lines while it is still running gives a wrong count (I reported 63 passes when the finished run printed 64 passed, 0 failed). Wait for the process to exit (a wait/notification on exit, or poll for the final summary line) and quote the suite's own final summary line, not a count you made yourself. Reviewers checking someone else's numbers should do the same before calling a count wrong.
