--------------------------------------
Summary: Eliminate long time.Sleep() calls from the application
test code
Key: YUNIKORN-2155
URL: https://issues.apache.org/jira/browse/YUNIKORN-2155
Project: Apache YuniKorn
Issue Type: Bug
Components: core - common, test - unit
Reporter: Peter Bacsko
{{TestResourceUsageAggregation()}} calls {{time.Sleep(3 * time.Second)}} three
times. It means this test case sleeps for 9 seconds in total.
Short sleeps can be acceptable (like the ones in {{{}TestStateTimeOut{}}}), but
this is a lot. We need a different approach here.
I recommend using a function variable like {{currentTime()}} which by default
calls {{time.Now()}} inside {{TrackedResource.AggregateTrackedResource()}}.
However, tests can change this to return an arbitrary {{time.Time}}. The
original reference of {{currentTime()}} is restored in a defer call.
{{TestFinishedTime}} also uses time.Sleep() which seems unnecessary.
