ktesting.TContext combines several different interfaces. This makes the code
simpler because less parameters need to be passed around.
An intentional side effect is that the apiextensions client interface becomes
available, which makes it possible to use CRDs. This will be needed for future
DRA tests.
Support for CRDs depends on starting the apiserver via
k8s.io/kubernetes/cmd/kube-apiserver/app/testing because only that enables the
CRD extensions. As discussed on Slack, the long-term goal is to replace the
in-tree StartTestServer with the one in staging, so this is going in the right
direction.
The new TContext interface combines a normal context and the testing interface,
then adds some helper methods. The context gets canceled when the test is done,
but that can also be requested earlier via Cancel.
The intended usage is to pass a single `tCtx ktesting.TContext` parameter
around in all helper functions that get called by a unit or integration test.
Logging is also more useful: Log[f] and Fatal[f] output is prefixed with
"[FATAL] ERROR: " to make it stand out more from regular log output.
If this approach turns out to be useful, it could be extended further (for
example, with a per-test timeout) and might get moved to a staging repository
to enable usage of it in other staging repositories.
To allow other implementations besides testing.T and testing.B, a custom
ktesting.TB interface gets defined with the methods expected from the
actual implementation. One such implementation can be ginkgo.GinkgoT().
Currently published image version doesn't include latest code changes,
for example CDI support.
Manifests include different and outdated image versions
snuck in there while I was working on the test, but is ultimately not necessary to test the functionality.
skipping healthz check resulted in leaking goroutines from poststarthooks.
Don't implement interfaces that trigger tests with in-line and
pre-provisioned vSphere volumes.
With cloud provider removal, the in-tree vSphere tests won't be able to
create a volume in vSphere and thus test in-line volumes in Pods and
pre-provisioned PVs. Only dynamically provisioned volumes can be used for
testing, because they're provisioned by the vSphere CSI driver.
Refactor the code related to creating an internal type load balancer in the e2e tests for network load balancers. The modification removes the check for the "azure" provider and updates it to only check for "gke" and "gce" providers. This change ensures that the test only runs when the cluster is using "gke" or "gce" as the provider. The counterpart test is in the out-of-tree cloud provider azure.
