1995627 - Longer xpcshell tests should start first when running in parallel

Status: RESOLVED FIXED

(Testing :: XPCShell Harness, enhancement)

Description

[Florian Quèze [:florian]]

Very often, the parallel execution phase of xpcshell test jobs has a significant time with only one or two tests still running at the end. Example profile: https://share.firefox.dev/4niH90G

Now that all long running tests have a requesttimeoutfactor annotation, we could use these annotations to sort the tests so the long tests start first.
