Summary: Golden test trace generation and validation
Key: YUNIKORN-3338
URL: https://issues.apache.org/jira/browse/YUNIKORN-3338
Project: Apache YuniKorn
Issue Type: Test
Components: core - common
Reporter: Dale Richardson
With some cross-cutting performance improvements, it can very useful to be able
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
activities, 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
