Description Jan Safranek 2020-03-09 15:48:57 UTC

Description of problem:

openshift-tests runs several tests in parallel (in a parallel suite). It is currently not possible to set the parallelism.

During CSI certification (included in openshift-tests binary) some users complain that the parallelism is too high for their small test clusters / storage backends.

Version-Release number of selected component (if applicable):
today's master, 46609de5524c18f5641e11139ae60ff5bc04260f

How reproducible:
always

Steps to Reproduce:
1. openshift-tests run openshift/csi
2. Check nr. of openshift-tests children

Actual results:
10

Expected results:
less, if user wants so

Additional info:
Looks like flag for &opt.Parallelism here would do the trick:

Merged but this is not something QE verifies.
