Some test cases can make nodes not ready and use DeferCleanup to bring
nodes back online. Checking if all nodes are online would fail
in such cases as AfterEach runs before DeferCleanup.
Scheduling nodes readines check to DeferCleanup should solve this
issue as nodes would be brought back to a `Ready` state before the
check.
- test/e2e/framework/*.go should have very minimal dependencies.
We can enforce that via import-boss.
- What each test/e2e/framework/* sub-package uses is less relevant,
although ideally it also should be as minimal as possible in each case.
Enforcing this via import-boss ensures that new dependencies get flagged as
problem and thus will get additional scrutiny. It might be okay to add them,
but it needs to be considered.
The recently introduced failure handling in ExpectNoError depends on error
wrapping: if an error prefix gets added with `fmt.Errorf("foo: %v", err)`, then
ExpectNoError cannot detect that the root cause is an assertion failure and
then will add another useless "unexpected error" prefix and will not dump the
additional failure information (currently the backtrace inside the E2E
framework).
Instead of manually deciding on a case-by-case basis where %w is needed, all
error wrapping was updated automatically with
sed -i "s/fmt.Errorf\(.*\): '*\(%s\|%v\)'*\",\(.* err)\)/fmt.Errorf\1: %w\",\3/" $(git grep -l 'fmt.Errorf' test/e2e*)
This may be unnecessary in some cases, but it's not wrong.
In the `NodeSupportsPreconfiguredRuntimeClassHandler`, update the check
for the runtime handler to return a failure if the
`/etc/containerd/config.toml` or `/etc/crio/crio.conf` config files do
not exist. If an error is returned, then the underlying test will be
skipped.
Test manually with starting a kind cluster and moving the containerd
config file and verifying that the test is skipped:
```
$ docker exec -it kind-worker /bin/bash
root@kind-worker:/# mv /etc/containerd/config.toml /etc/containerd/config.toml.bak
```
```
make WHAT="test/e2e/e2e.test"
$ ./_output/bin/e2e.test -kubeconfig /tmp/kubeconfig_kind -ginkgo.focus=".*should run a Pod requesting a RuntimeClass with a configured handler.*" --num-nodes=1 2>&1 -ginkgo.v=1 | tee -i "/tmp/build-log.txt"

There are two runtime class tests which required the container runtime
config to include explicit configuration for `test-handler`. The current
logic skips these tests in non GCE environments. This skip is too strict
since the test is skipped in node e2e environments and in other
environments such as kind, which support running the test and also
configure `test-handler`.
Instead of skipping based on provider, add a new function
`NodeSupportsPreconfiguredRuntimeClassHandler` which examines the
underlying container runtime config and checks if the config includes
`test-handler`. The check is a bit brittle since it assumes container
runtime config paths, but it is a net improvement over skipping the test
entirely on non GCE environments.
This results in the test working in the common test environments, namely
GCE kube-up, node e2e, and kind.

All code must use the context from Ginkgo when doing API calls or polling for a
change, otherwise the code would not return immediately when the test gets
aborted.
This addresses a problem caused by
https://github.com/kubernetes/kubernetes/pull/112043: because the AfterEach
which invokes AllNodesReady always runs, including tests that skipped early,
those tests ran into a nil pointer access. This increased the size of log
files. The tests still worked.
The "todo" packages were necessary while moving code around to avoid hitting
cyclic dependencies. Now that any sub package can depend on the framework, they
are no longer needed and the code can be moved into the normal sub packages.
- update all the import statements
- run hack/pin-dependency.sh to change pinned dependency versions
- run hack/update-vendor.sh to update go.mod files and the vendor directory
- update the method signatures for custom reporters

Because these tests don't run in the CI, the test did not quite match the
actual code anymore. Apparently a retry mechanism was added after the test was
written.
Now, internalStaticIP is hard-coded to "10.240.11.11". Such IP works
for aks-engine cluster but not for CAPZ ones (node-subnet 10.1.0.0/16)

Tests "Multi-AZ Cluster Volumes" should consider only nodes that are
schedulable and *untainted* when computing AZ where to run the tests.
GetReadySchedulableNodes() already filters schedulable + untainted nodes,
no need to do it again in GetSchedulableClusterZones().
Ensure resources are created in zone with schedulable
nodes. For example, if we have 4 zones with 3 zones
having worker nodes and 1 zone having master nodes(unscheduable
for workloads), we should not create resources like PV, PVC or
pods in that zone.
A number of e2e tests are useful to run after the system has been
disrupted or is in the progress of being disrupted, but the current
suite and test logic blocks progress waiting for all nodes to be
healthy.
By passing -1 to --minStartupPods or --allowed-not-ready-nodes flags
the caller can bypass wait logic before and after test suites that
would prevent running e2e during disruption. This allows use of parts
of the e2e suite during cluster duress to verify that controllers or
components still function.
Dual stack services can have two ClusterIPs, we already have tests that
exercise the connectivity from different scenarios to the first
ClusterIP of the service.
This PR adds a new functionality to the e2e network utils to enable
DualStack services, and replicate the same tests but using the
secondary ClusterIP, so we cover the connectivity to both cluster IPs.
We hardcode the index number in the KubeProxy/Conntrack e2es and
CollectAddresses returns 4 mixed IP Family addresses in a dualstack
cluster. This change ensures that the serverNodeInfo.nodeIP has only
valid addresses for the expected IPFamily per test case.
