User Story

As an odo dev I want, the integration tests related to binding error out immediately if the OLM is not installed on the cluster, or if there are situations we know for sure the operator does not exist on the cluster, So that, tests can fail quickly.

Acceptance Criteria

• [ ] It should error out immediately if OLM is not installed (perhaps by checking the csv resource)
• [ ] It should error out immediately if subscriptions resource returns nothing within a few seconds, because a csv might take some time, but subscriptions is quick to appear once the operator installation script is applied.
