So I've run a successful test in the Dev Console. One of the columns visible on that tab is duration. My result is "0:28". I'm not sure if that is 28 seconds, .28 seconds or 28 milliseconds. Any ideas? BTW, the log shows the test starting at:


and ending at


which appears to be a total duration of just under 23 seconds for everything. That suggests 28 seconds is not the answer, but I'd like to know what the units are for sure.

Yes those are milliseconds. You can see them talking about this topic here: https://developer.salesforce.com/page/Troubleshooting_Apex_Performance_Problems (Where there are 0.2 'duration' gaps which are milliseconds in between each case)

in your case that will be 280 milliseconds

  • Thanks! That link has reminded me that I can also wrap key line(s) with system.debug() statements to get more specific.

  • I usually wait a day or two before adding the check (encourages other answers), but I don't think there's much more to say on this one.
