Can you explain what you mean by "pending for a while"? Are you referring to a situation which is in created but not running? If then, job will get into running state after retry?

I meant unschedulable pods (gang scheduling).

If before the training-operator updates the job condition from Runnng=false to Running=true, this test code gets the job condition and the job condition has Running=false or doesn't have Running condition, this test unintended passes.
So, let's imagine the following situation:
Current e2e:
- Test: Deploy job with gang scheduling setting (.runPolicy.schedulingPolicy).
- Operator: Failed to set schedulerName=volcano to the job. Or create an incorrect PodGroup.
- Test: Get the job with
Running=falseor withoutRunningcondition. - Pods: Pods are immediately scheduled to Node and start since the job doesn't have appropriate gang scheduling settings.
- Operator: Update the job condition with
Running=true. - Test: Succeeded! (Unintended)

Note: This verify_unschedulable_job_e2e function verifies that gang scheduler integrations work well.

Thanks for the explanation.

@johnugeorge In fact, even though we forgot to set volcano to schedulerName in the podSpec, e2e passed in #1831.

This is necessary and it used to set the scheduler for gang-schedule e2e. I forget to changed it in last pr, sorry.

What this PR does / why we need it:
When enabling the gang-scheduling, we don't check whether jobs have been pending for a while in e2e.
So tests for the gang-scheduling will pass if jobs meet the
Created=trueandRunning=falseconditions for just a moment.I added a check that jobs have been pending for a while.
Also, I fixed a test bug that
volcanoisn't set to jobs as a schedulerName when testing for volcano integration.Note: I faced errors in #1834.
