Functions ¶

func AssertRequestResponseAsCBOR ¶

func AssertRequestResponseAsCBOR(t testing.TB) transport.WrapperFunc

AssertRequestResponseAsCBOR returns a transport.WrapperFunc that will report a test error if a non-empty request or response body contains data that does not appear to be CBOR-encoded.

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 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, forceCreate bool)

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 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.
