Trying to speed up the test cases that require additional kubernetes APIs. Each time a test suite or test case requires an additional API (like OpenShift Routes or Kiali CRDs), provided by k8s.io/apiextensions, a fixed 2 seconds delay is introduced. There's no way to reduce that delay by using envtest features or APIServer CLI flags. The delays are introduced by kube-aggregator, apiextensions, and others: https://github.com/kubernetes/kube-aggregator/blob/a00232cf7e758c2771b3542033bec19e69e6451a/pkg/controllers/openapiv3/controller.go#L34 https://github.com/kubernetes/apiextensions-apiserver/blob/8db5ab628dd026827c1c9677944432db70c065c3/pkg/apiserver/customresource_handler.go#L381-L394 To mitigate this, we're going to declare all CRDs used in the test in the common_test.go TestMain function. This will make sure we only have a single delay at the beginning of the entire test suite instead of per test suite or test case. The CRDs are NOT served by default. For each test suite we'll be able to enable them or disable them by using the EnvTestEnableCRD and EnvTestDisableCRD functions. These will also ensure that the API server lists the new APIs or not.

Merging, I need this as a prereq to complete #386 test improvements. |

Trying to speed up the test cases that require additional
kubernetes APIs.
Each time a test suite or test case requires an additional
API (like OpenShift Routes or Kiali CRDs), provided by
k8s.io/apiextensions, a fixed 2 seconds delay is introduced.
There's no way to reduce that delay by using envtest features
or APIServer CLI flags.
The delays are introduced by kube-aggregator, apiextensions, and others:

To mitigate this, we're going to declare all CRDs used in the test in
the common_test.go TestMain function.
This will make sure we only have a single delay at the beginning of
the entire test suite instead of per test suite or test case.
The CRDs are NOT served by default.
For each test suite we'll be able to enable them or disable them
by using the EnvTestEnableCRD and EnvTestDisableCRD functions.
These will also ensure that the API server lists the new APIs or not.
