> Key: YUNIKORN-3338
> URL: https://issues.apache.org/jira/browse/YUNIKORN-3338
> Project: Apache YuniKorn
> Issue Type: Test
> Components: core - common
> Reporter: Dale Richardson
> Priority: Major
> Labels: pull-request-available
>
> With some cross-cutting performance improvements, it can very useful to be
> able to provide evidence that there has been no functional change to the
> underlying scheduling decisions made by Yunikorn.
> One way of doing this is to check in a canonical trace file of scheduling
> decisions, plus a testing harness that can remove all sources of randomness
> from the decision processes, and drives a series of set scenarios through to
> scheduling decisions. The testing can simply then be unit tests executing
> the scenario and comparing to the previous checked in trace files. Either
> the change in behaviour is deliberate, in which case an updated trace can be
> generated and checked in, or the trace file can help pinpoint an in-advertant
> change in scheduling behaviour
