585396 - Log how long tests take to run

Status: RESOLVED FIXED

(Testing :: Mochitest, defect)

Description

[Dave Townsend [:mossop]]

I'm hitting a problem where occasionally some tests of mine are timing out on Windows debug runs. The last time this happened it turned out that the test was just always bordering on the edge of timing out and would just randomly spill over without it being the cause of a problem. To try to figure out if that is the case with the other tests I want to see how long the tests actually take on tinderbox in passing runs. I figured the information would be useful for all tests rather than just mine.

This is a simple patch with just one niggle. Do we mark the start of the test as being when we first load the script, when we call test() or when test() completes and we wait for finish to be called. The latter is most useful for determining whether tests are close to timing out, since this is when the timeout starts, but maybe the full time makes more sense.

this looks sufficiently innocuous.

a=sdwilsh to land on mozilla-central (not that I can set that flag, but you technically need approval I think)
