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.

AddOrUpdateLabelOnNode adds the given label key and value to the given node or updates value.

func AddOrUpdateLabelOnNodeAndReturnOldValue ¶ added in v1.8.0

func AddOrUpdateLabelOnNodeAndReturnOldValue(c clientset.Interface, nodeName string, labelKey, labelValue string) string

AddOrUpdateLabelOnNodeAndReturnOldValue adds the given label key and value to the given node or updates value and returns the old label value.

func AllNodesReady ¶

func AllNodesReady(c clientset.Interface, timeout time.Duration) error

func AssertCleanup ¶

func AssertCleanup(ns string, selectors ...string)

AssertCleanup asserts that cleanup of a namespace wrt selectors occurred.

func BlockNetwork ¶

func BlockNetwork(from string, to string)

BlockNetwork blocks network between the given from value and the given to value. 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 CheckConnectivityToHost ¶

CreatePVCPV creates 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.

func CreatePVPVC ¶ added in v1.6.0

func CreatePVPVC(c clientset.Interface, pvConfig PersistentVolumeConfig, pvcConfig PersistentVolumeClaimConfig, ns string, preBind bool) (*v1.PersistentVolume, *v1.PersistentVolumeClaim, error)

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

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

CreatePVsPVCs creates the desired number of PVs and PVCs and returns them in separate maps. If the number of PVs != the number of PVCs then the min of those two counts is the number of PVs expected to bind. 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.

}

TestContextType contains test settings and global state. Due to historic reasons, it is a mixture of items managed by the test framework itself, cloud providers and individual tests. The goal is to move anything not required by the framework into the code which uses the settings.

The recommendation for those settings is:

They are stored in their own context structure or local variables.
The standard `flag` package is used to register them. The flag name should follow the pattern <part1>.<part2>....<partn> where the prefix is unlikely to conflict with other tests or standard packages and each part is in lower camel case. For example, test/e2e/storage/csi/context.go could define storage.csi.numIterations.
framework/config can be used to simplify the registration of multiple options with a single function call: var storageCSI { NumIterations `default:"1" usage:"number of iterations"` } _ config.AddOptions(&storageCSI, "storage.csi")
The direct use Viper in tests is possible, but discouraged because it only works in test suites which use Viper (which is not required) and the supported options cannot be discovered by a test suite user.

Test suite authors can use framework/viper to make all command line parameters also configurable via a configuration file.

var TestContext TestContextType

TestContext should be used by all tests to access common context data.

type TestDataSummary ¶

type TestDataSummary interface {
	SummaryKind() string
	PrintHumanReadable() string
	PrintJSON() string
}

TestDataSummary is an interface for managing test data.

type TimestampedSize ¶

type TimestampedSize struct {
	// contains filtered or unexported fields
}

TimestampedSize contains a size together with a time of measurement.

type UDPPokeParams ¶ added in v1.13.6

type UDPPokeParams struct {
	Timeout  time.Duration
	Response string
}

UDPPokeParams is a struct for UDP poke parameters.

type UDPPokeResult ¶ added in v1.13.6

type UDPPokeResult struct {
	Status   UDPPokeStatus
	Error    error  // if there was any error
	Response []byte // if code != 0
}

UDPPokeResult is a struct for UDP poke result.

func PokeUDP ¶ added in v1.13.6

func PokeUDP(host string, port int, request string, params *UDPPokeParams) UDPPokeResult

PokeUDP tries to connect to a host on a port and send the given request. Callers can specify additional success parameters, if desired.

The result status will be characterized as precisely as possible, given the known users of this.

The result error will be populated for any status other than Success.

The result response will be populated if the UDP transaction was completed, even if the other test params make this a failure).

type UDPPokeStatus ¶ added in v1.13.6

type UDPPokeStatus string

UDPPokeStatus is string for representing UDP poke status.

const (
	// UDPSuccess is UDP poke status which is success.
	UDPSuccess UDPPokeStatus = "Success"
	// UDPError is UDP poke status which is error.
	UDPError UDPPokeStatus = "UnknownError"
	// UDPTimeout is UDP poke status which is timeout.
	UDPTimeout UDPPokeStatus = "TimedOut"
	// UDPRefused is UDP poke status which is connection refused.
	UDPRefused UDPPokeStatus = "ConnectionRefused"
	// UDPBadResponse is UDP poke status which is bad response.
	UDPBadResponse UDPPokeStatus = "BadResponse"
)

type What ¶ added in v1.13.0

type What struct {
	Kind string `json:"kind"`
}

What is a subset of metav1.TypeMeta which (in contrast to metav1.TypeMeta itself) satisfies the runtime.Object interface.

func (*What) DeepCopy ¶ added in v1.13.0

func (in *What) DeepCopy() *What

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new What.

func (*What) DeepCopyInto ¶ added in v1.13.0

func (in *What) DeepCopyInto(out *What)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out.

func (*What) DeepCopyObject ¶ added in v1.13.0

func (in *What) DeepCopyObject() runtime.Object

DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.

func (*What) GetObjectKind ¶ added in v1.13.0

func (in *What) GetObjectKind() schema.ObjectKind

GetObjectKind returns the ObjectKind schema

type WorkItem ¶

type WorkItem struct {
	// contains filtered or unexported fields
}

WorkItem is a command for a worker that contains an IP of machine from which we want to gather data and paths to all files we're interested in.
