framework.SIGDescribe is better because:
- Ginkgo uses the source code location of the test, not of the wrapper,
when reporting progress.
- Additional annotations can be passed.
To make this a drop-in replacement, framework.SIGDescribe generates a function
that can be used instead of the former SIGDescribe functions.
windows.SIGDescribe contained some additional code to ensure that tests are
skipped when not running with a suitable node OS. This gets moved into a
separate wrapper generator, to allow using framework.SIGDescribe as intended.
To ensure that all callers were modified, the windows.sigDescribe isn't
exported anymore (wasn't necessary in the first place!).
These wrapper functions set labels in addition to injecting the annotation into
the test text. It then becomes possible to select tests in different ways:
ginkgo -v --focus="should respect internalTrafficPolicy.*\[FeatureGate:ServiceInternalTrafficPolicy\]"
ginkgo -v --label-filter="FeatureGate:ServiceInternalTrafficPolicy"
ginkgo -v --label-filter="Beta"
When a test runs, ginkgo shows it as:
[It] should respect internalTrafficPolicy=Local Pod to Pod [FeatureGate:ServiceInternalTrafficPolicy] [Beta] [FeatureGate:ServiceInternalTrafficPolicy, Beta]
The test name and the labels at the end are in different colors. Embedding the
annotations inside the text is redundant and only done because users of the e2e
suite might expect it. Also, our tooling that consumes test results currently
doesn't know about ginkgo labels.
Environments, features and node features as described by
https://github.com/kubernetes/enhancements/tree/master/keps/sig-testing/3041-node-conformance-and-features
are also supported.
The framework and thus (at the moment) test/e2e do not have any pre-defined
environments and features. Adding those and modifying tests will follow in
a separate commit.
If something goes wrong during the test registration phase, the only solution
so far was to panic. This is not user-friendly and only allows to report one
problem at a time.
If initialization can continue, then a better solution is to record a bug,
continue, and then report all bugs together.
This also works when just listing tests. The new verify-e2e-suites.sh uses that
to check all test suites (identified as "packages that call
framework.AfterReadingAllFlags", with some exceptions) as part of
pull-kubernetes-verify.
Example output for a fake
framework.RecordBug(framework.NewBug("fake bug during SIGDescribe", 0))
in test/e2e/storage/volume_metrics.go:
```
$ hack/verify-e2e-suites.sh
go version go1.21.1 linux/amd64
ERROR: E2E test suite invocation failed for test/e2e.
ERROR: E2E suite initialization was faulty, these errors must be fixed:
ERROR: test/e2e/storage/volume_metrics.go:49: fake bug during SIGDescribe
E2E suite test/e2e_kubeadm passed.
E2E suite test/e2e_node passed.
```
-list-tests is a more concise alternative for `ginkgo --dry-run` with one line
per test. In contrast to `--dry-run`, it really lists all tests. `--dry-run`
without additional parameters uses the default skip expression from the E2E
context, which filters out flaky and feature-gated tests. The output includes
the source code location where each test is defined. It is sorted by test
name (not source code location) because that order is independent of
reorganizing the source code and ordering by location can be achieved with
"sort".
-list-labels has no corresponding feature in Ginkgo.
One possible usage is to figure out what values might make sense for
-focus/skip/label-filter.
Unit tests will follow in a future commit.
Always printing "Enabling in-tree volume drivers" whenever the E2E suite is
initializing doesn't provide any useful information and makes output of the
upcoming -list-tests look weird.
This field is not needed, IPAddresses are unique and
the name is canonicalized to avoid duplicates.

The use of "Endpoint" vs "Endpoints" in these type names is tricky
because it doesn't always make sense to use the same singular/plural
convention as the corresonding service-related types, since often the
service-related type is referring to a single service while the
endpoint-related type is referring to multiple endpoint IPs.
The "endpointsInfo" types in the iptables and winkernel proxiers are
now "endpointInfo" because they describe a single endpoint IP (and
wrap proxy.BaseEndpointInfo).
"UpdateEndpointMapResult" is now "UpdateEndpointsMapResult", because
it is the result of EndpointsMap.Update (and it's clearly correct for
EndpointsMap to have plural "Endpoints" because it's a map to an array
of proxy.Endpoint objects.)
"EndpointChangeTracker" is now "EndpointsChangeTracker" because it
tracks changes to the full set of endpoints for a particular service
(and the new name matches the existing "endpointsChange" type and
"Proxier.endpointsChanges" fields.)
Instead of invoking verify-golangci-lint.sh directly from Prow jobs,
those Prow jobs should use "make verify WHAT=...". The advantage is
that the common code for running verify targets will be used, which
includes producing JUnit files.
Providing simple wrappers for strict linting of PRs (=
verify-golangci-lint-pr.sh) and event stricter linting of PRs with hints
enabled (= verify-golangci-lint-pr-hints.sh) enables those WHAT targets.
Include number of requested and available CPUs in the error message
when the assignment of CPUs fails because there are less available
CPUs than requested.
