The existing walk.go and conformance.txt have a few shortcomings
which we'd like to resolve:
- difficult to get the full test name due to test context nesting
- complicated AST logic and understanding necessary due to the
different ways a test can be invoked and written
This changes the AST parsing logic to be much more simple and simply
looks for the comments at/around a specific line. This file/line
information (and the full test name) is gathered by a custom ginkgo
reporter which dumps the SpecSummary data to a file.
Also, the SpecSummary dump can, itself, be potentially useful for
other post-processing and debugging tasks.

The service session affinity allows to set the maximum session
sticky timeout.
This commit adds e2e tests to check that the session is sticky
before the timeout and is not after.
Executing commands in pods is expensive in terms of time and the
execution time is unpredictable and random.
The session affinity tests send several http requests from a pod
to check that the session is sticky. Instead of executing one
http request at a time, we can execute several requests from the
pod at one time and process the output.
The image "gcr.io/authenticated-image-pulling/windows-nanoserver:v1" is not a
manifest list, and it is only useful for Windows Server 1809, which means that the
test "should be able to pull from private registry with secret" will fail for
environments with Windows Server 1903, 1909, or any other future version we might
want to test.
This commit adds the the ability to have an alternative private image to pull by
using a configurable docker config file which contains the necessary credentials
needed to pull the image.
Add a new e2e test to test multiple stacked NetworkPolicies with
Except clauses in IPBlock which overlaps with an allowed CIDR in
another NetworkPolicy. This test ensures that the order of the
creation of NetworkPolicies should not matter while evaluating
a Pods access to another Pod.
Previously, we've centralized several images into agnhost, including
test-webserver.
The Hybrid cluster network test was using the test-webserver image, and
was updated to use agnhost, but without properly making it so it behaves like
test-webserver, resulting in a failing test.
Similar functionality is required across e2e tests for RuntimeClass.
Let's create runtimeclass as part of the framework/node package.

Use bytes instead of strings, and slice in-place filter
(see https://github.com/golang/go/wiki/SliceTricks#filter-in-place)
to avoid copying strings around.
In my benchmark it shows almost 2x improvement:
BenchmarkString-8 1477207 10198 ns/op
BenchmarkBuffer-8 1561291 7622 ns/op
BenchmarkInPlace-8 2295714 5202 ns/op
String is the original implementation, Buffer is an intermediary
one that uses strings.Builder, and InPlace is the one from this commit.

Add a new e2e test to test the Except clauses in IPBlock CIDR
based NetworkPolicies. This test adds an egress rule which
allows client to connect to a CIDR which includes the
ServerPod's IP, however carves an except subnet which excludes
this ServerPod.
The test "should enforce egress policy allowing traffic to a server in a
different namespace based on PodSelector and NamespaceSelector
[Feature:NetworkPolicy]" is flaky because it doesn't wait for the server
Pod to be ready before testing traffic via its service, then even the
NetworkPolicy allows it, the SYN packets will be rejected by iptables
because the service has no endpoints at that moment.
This PR fixes it by making it wait for Pods to be ready like other
tests.
This is useful for logs from daemonset pods because for those it is
often relevant which node they ran on because they interact with
resources or other pods on the host.
To keep the log prefix short, it gets limited to a maximum length of
10 characters.
Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- resource-consumer-controller
- test-webserver
Commit 69a473be3 broke the test case (that was checking
that a file from a volume can't be read) by adding a
(wrong) assumption that error should be nil.
Fix the assumption (we do expect the error here).
Note that we were checking file contents before; now when
we check the error from read, checking the contents is
redundant.
The other issue with the test is SELinux should be in enforcing
mode for this to work, so let's check that first to avoid
false positives.
