Provider controller integration tests

[alexgeorgousis]

Overview

We want to add integration tests (running in minikube) for the Provider controller. Specifically we want to test that the Provider controller manages the provider service Deployment correctly in every stage of the Provider resource lifecycle.

We're raising a dedicated issue to do this since we don't have any integration tests for any of our controllers, so we'll need to add quite a bit of scaffolding to introduce them for the first time.

Test cases

• Provider resource Create | Update | Delete:
  • Create Provider -> Assert SynchronizationState = Creating -> Assert Deployment and Service eventually created and healthy -> Assert SynchronizationState = Succeeded
  • Update Provider -> Assert SynchronizationState = Updating -> Assert Deployment and Service eventually updated and healthy -> Assert SynchronizationState = Succeeded
  • Delete Provider -> Assert SynchronizationState = Deleting -> Assert Deployment and Service eventually deleted
• Deployment resource Update | Delete:
  • Update Deployment -> Assert Provider SynchronizationState = Updating -> Assert Deployment eventually rolled back and healthy -> Assert Provider SynchronizationState = Succeeded
  • Delete Deployment -> Assert Provider SynchronizationState = Creating -> Assert Deployment eventually rolled back and healthy -> Assert Provider SynchronizationState = Succeeded
• Service resource Update | Delete:
  • Identical to Deployment above
