Josh Bleecher Snyder ffe8bce740 cmd/stress: print elapsed time, percentage failure ... Add more information to the output of stress. Prior to this change, stress printed lines like: 8288 runs so far, 2 failures After this change, stress prints lines like: 1m5s: 8288 runs so far, 2 failures (0.02%) I've found the timing information to be helpful in that it helps me anticipate how long a new stress run might take to reach some number of iterations I've deemed necessary to convince myself that a bug has been fixed. I've found the % failure to be helpful when there are multiple failures; I can use them to gauge whether I've made the test more reliable. I've been using this patch for a while and found it helpful on numerous occasions, so I figured I should upstream it.
