Constants

)

Variables

var MinVerbosity = 4

MinVerbosity determines the minimum klog verbosity when running tests that involve the apiserver. This overrides the -v value from the command line, i.e. -v=0 has no effect when MinVerbosity is 4 (the default). Tests can opt out of this by setting MinVerbosity to zero before starting the control plane or choose some different minimum verbosity.

Functions

func CreateNamespaceOrDie

func CreateNamespaceOrDie(c clientset.Interface, baseName string, t testing.TB) *v1.Namespace

CreateNamespaceOrDie creates a namespace.

func DefaultEtcdOptions

func DefaultEtcdOptions() *options.EtcdOptions

DefaultEtcdOptions are the default EtcdOptions for use with integration tests.

func DefaultOpenAPIConfig

func DefaultOpenAPIConfig() *openapicommon.Config

DefaultOpenAPIConfig returns an openapicommon.Config initialized to default values.

func DefaultOpenAPIV3Config

func DefaultOpenAPIV3Config() *openapicommon.OpenAPIV3Config

DefaultOpenAPIV3Config returns an openapicommon.Config initialized to default values.

func DefaultTestServerFlags

func DefaultTestServerFlags() []string

DefaultAPIServerFlags returns the default flags used to run kube-apiserver on tests

func DeleteNamespaceOrDie

func DeleteNamespaceOrDie(c clientset.Interface, ns *v1.Namespace, t testing.TB)

DeleteNamespaceOrDie deletes a namespace.

func EtcdMain

func EtcdMain(tests func() int)

EtcdMain starts an etcd instance before running tests.

func Filter

func Filter(nodeList *v1.NodeList, fn func(node v1.Node) bool)

Filter filters nodes in NodeList in place, removing nodes that do not satisfy the given condition

func GetEtcdURL

func GetEtcdURL() string

GetEtcdURL returns the URL of the etcd instance started by EtcdMain or StartEtcd.

func GoleakCheck

func GoleakCheck(tb testing.TB, opts ...goleak.Option)

GoleakCheck sets up leak checking for a test or benchmark. The check runs as cleanup operation and records an error when goroutines were leaked.

func IgnoreBackgroundGoroutines

func IgnoreBackgroundGoroutines() []goleak.Option

IgnoreBackgroundGoroutines returns options for goleak.Find which ignore goroutines created by "go test" and init functions, like the one from go.opencensus.io/stats/view/worker.go.

Goroutines that normally get created later when using the apiserver get created already when calling this function, therefore they also get ignored.

func IsConditionSetAsExpected

func IsConditionSetAsExpected(node *v1.Node, conditionType v1.NodeConditionType, wantTrue bool) bool

IsConditionSetAsExpected returns a wantTrue value if the node has a match to the conditionType, otherwise returns an opposite value of the wantTrue with detailed logging.

func IsConditionSetAsExpectedSilent

func IsConditionSetAsExpectedSilent(node *v1.Node, conditionType v1.NodeConditionType, wantTrue bool) bool

IsConditionSetAsExpectedSilent returns a wantTrue value if the node has a match to the conditionType, otherwise returns an opposite value of the wantTrue.

func IsNodeReady

func IsNodeReady(node *v1.Node) bool

IsNodeReady returns true if: 1) it's Ready condition is set to true 2) doesn't have NetworkUnavailable condition set to true

func IsNodeSchedulable

func IsNodeSchedulable(node *v1.Node) bool

IsNodeSchedulable returns true if: 1) doesn't have "unschedulable" field set 2) it also returns true from IsNodeReady

func NewIntegrationTestNodePreparer

func NewIntegrationTestNodePreparer(client clientset.Interface, countToStrategy []testutils.CountToStrategy, nodeNamePrefix string) testutils.TestNodePreparer

NewIntegrationTestNodePreparer creates an IntegrationTestNodePreparer configured with defaults.

func NewIntegrationTestNodePreparerWithNodeSpec

func NewIntegrationTestNodePreparerWithNodeSpec(client clientset.Interface, countToStrategy []testutils.CountToStrategy, nodeSpec *v1.Node) testutils.TestNodePreparer

NewIntegrationTestNodePreparerWithNodeSpec creates an IntegrationTestNodePreparer configured with nodespec.

func NewTBWriter

func NewTBWriter(tb testing.TB) io.Writer

NewTBWriter creates an io.Writer which turns each write into a tb.Log call.

Note that no attempts are made to determine the actual call site because our caller doesn't know about the TB instance and thus cannot mark itself as helper. Therefore the code here doesn't do it either and thus shows up as call site in the testing output. To avoid that, contextual logging and ktesting have to be used.

func RedirectKlog

func RedirectKlog(tb testing.TB, output io.Writer) func()

RedirectKlog modifies the global klog logger so that it writes via the given writer. This only works when different tests run sequentially.

The returned cleanup function restores the previous state. Beware that it is not thread-safe, all goroutines which call klog must have been stopped.

func RunCustomEtcd

func RunCustomEtcd(dataDir string, customFlags []string, output io.Writer) (url string, stopFn func(), err error)

RunCustomEtcd starts a custom etcd instance for test purposes.

func SharedEtcd

func SharedEtcd() *storagebackend.Config

SharedEtcd creates a storage config for a shared etcd instance, with a unique prefix.

func StartEtcd

func StartEtcd(tb testing.TB, etcdOutput io.Writer)

StartEtcd starts an etcd instance inside a test. It will abort the test if startup fails and clean up after the test automatically. Stdout and stderr of the etcd binary go to the provided writer.

In contrast to EtcdMain, StartEtcd will not do automatic leak checking. Tests can decide if and where they want to do that.

Starting etcd multiple times per test run instead of once with EtcdMain provides better separation between different tests.

Types

type IntegrationTestNodePreparer

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

IntegrationTestNodePreparer holds configuration information for the test node preparer.

func (*IntegrationTestNodePreparer) CleanupNodes

func (p *IntegrationTestNodePreparer) CleanupNodes(ctx context.Context) error

CleanupNodes deletes existing test nodes.

func (*IntegrationTestNodePreparer) PrepareNodes

func (p *IntegrationTestNodePreparer) PrepareNodes(ctx context.Context, nextNodeIndex int) error

PrepareNodes prepares countToStrategy test nodes.

type TearDownFunc

type TearDownFunc func()

func StartTestServer

func StartTestServer(ctx context.Context, t testing.TB, setup TestServerSetup) (client.Interface, *rest.Config, TearDownFunc)

StartTestServer runs a kube-apiserver, optionally calling out to the setup.ModifyServerRunOptions and setup.ModifyServerConfig functions TODO (pohly): convert to ktesting contexts

type TestServerSetup

type TestServerSetup struct {
	ModifyServerRunOptions func(*options.ServerRunOptions)
	ModifyServerConfig     func(*controlplane.Config)
}

TestServerSetup holds configuration information for a kube-apiserver test server.
