Overview

Package framework contains provider-independent helper code for building and running E2E tests with Ginkgo. The actual Ginkgo test suites gets assembled by combining this framework, the optional provider support code and specific tests via a separate .go file like Kubernetes' test/e2e.go.

func BlockNetwork

func BlockNetwork(from string, to string)

The following helper functions can block/unblock network from source host to destination host by manipulating iptable rules. This function assumes it can ssh to the source host.

Caution: Recommend to input IP instead of hostnames. Using hostnames will cause iptables to do a DNS lookup to resolve the name to an IP address, which will slow down the test and cause it to fail if DNS is absent or broken.

Suggested usage pattern:

func foo() {
	...
	defer UnblockNetwork(from, to)
	BlockNetwork(from, to)
	...
}

func CreatePVC added in v1.6.0

create the PVC resource. Fails test on error.

func CreatePVCPV added in v1.6.0

Create a PVC followed by the PV based on the passed in nfs-server ip and namespace. If the "preBind" bool is true then pre-bind the PV to the PVC via the PV's ClaimRef. Return the pv and pvc to reflect the created objects. Note: in the pre-bind case the real PVC name, which is generated, is not

known until after the PVC is instantiated. This is why the pvc is created
before the pv.

If a Create error occurs, the returned maps may contain pv and pvc entries for the resources that were successfully created. In other words, when the caller sees an error returned, it needs to decide what to do about entries in the maps. Note: when the test suite deletes the namespace orphaned pvcs and pods are deleted. However,

orphaned pvs are not deleted and will remain after the suite completes.

Also, it ensures that at least minPods are running and ready. It has separate behavior from other 'wait for' pods functions in that it requests the list of pods on every iteration. This is useful, for example, in cluster startup, because the number of pods increases while waiting. All pods that are in SUCCESS state are not counted.

Cleaning up after a test can be triggered in two ways:

  • the test invokes the returned cleanup function, usually in an AfterEach
  • the test suite terminates, potentially after skipping the test's AfterEach (https://github.com/onsi/ginkgo/issues/222)

PatchItems has the some limitations as LoadFromManifests: - only some common items are supported, unknown ones trigger an error - only the latest stable API version for each item is supported

LoadFromManifests loads .yaml or .json manifest files and returns all items that it finds in them. It supports all items for which there is a factory registered in Factories and .yaml files with multiple items separated by "---". Files are accessed via the "testfiles" package, which means they can come from a file system or be built into the binary.

LoadFromManifests has some limitations:

  • aliases are not supported (i.e. use serviceAccountName instead of the deprecated serviceAccount, https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.11/#podspec-v1-core) and silently ignored
  • the latest stable API version for each item is used, regardless of what is specified in the manifest files

This is done by: - creating namespaced items inside the test's namespace - changing the name of non-namespaced items like ClusterRole

PatchItems has some limitations: - only some common items are supported, unknown ones trigger an error - only the latest stable API version for each item is supported

func (*Framework) PatchName added in v1.13.0
