func AfterTest

func AfterTest(t *testing.T)

AfterTest is meant to run in a defer that executes after a test completes. It will detect common goroutine leaks, retrying in case there are goroutines not synchronously torn down, and fail the test if any goroutines are stuck.

func AssertEqual

func AssertEqual(t *testing.T, e, a interface{}, msg ...string)

func AssertFalse

func AssertFalse(t *testing.T, v bool, msg ...string)

func AssertNil

func AssertNil(t *testing.T, v interface{})

func AssertNotNil

func AssertNotNil(t *testing.T, v interface{})

func AssertTrue

func AssertTrue(t *testing.T, v bool, msg ...string)

func CheckAfterTest

func CheckAfterTest(d time.Duration) error

CheckAfterTest returns an error if AfterTest would fail with an error.

func CheckLeakedGoroutine

func CheckLeakedGoroutine() bool

CheckLeakedGoroutine verifies tests do not leave any leaky goroutines. It returns true when there are goroutines still running(leaking) after all tests.

import "go.etcd.io/etcd/pkg/testutil"

func TestMain(m *testing.M) {
	v := m.Run()
	if v == 0 && testutil.CheckLeakedGoroutine() {

func TestSample(t *testing.T) {
	defer testutil.AfterTest(t)

func FatalStack

func FatalStack(t *testing.T, s string)

FatalStack helps to fatal the test and print out the stacks of all running goroutines.

func MustNewURL

func MustNewURL(t *testing.T, s string) *url.URL

func MustNewURLs

func MustNewURLs(t *testing.T, urls []string) []url.URL

func Poll

func Poll(interval time.Duration, timeout time.Duration, condition ConditionFunc) (bool, error)

Poll calls a condition function repeatedly on a polling interval until it returns true, returns an error or the timeout is reached. If the condition function returns true or an error before the timeout, Poll immediately returns with the true value or the error. If the timeout is exceeded, Poll returns false.

func WaitSchedule

func WaitSchedule()

WaitSchedule briefly sleeps in order to invoke the go scheduler. TODO: improve this when we are able to know the schedule or status of target go-routine.


type Action

type Action struct {
	Name   string
	Params []interface{}

type ConditionFunc

type ConditionFunc func() (bool, error)

ConditionFunc returns true when a condition is met.

type PauseableHandler

type PauseableHandler struct {
	Next http.Handler
	// contains filtered or unexported fields

func (*PauseableHandler) Pause

func (ph *PauseableHandler) Pause()

func (*PauseableHandler) Resume

func (ph *PauseableHandler) Resume()

func (*PauseableHandler) ServeHTTP

func (ph *PauseableHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Recorder

type Recorder interface {
	// Record publishes an Action (e.g., function call) which will
	// be reflected by Wait() or Chan()
	Record(a Action)
	// Wait waits until at least n Actions are available or returns with error
	Wait(n int) ([]Action, error)
	// Action returns immediately available Actions
	Action() []Action
	// Chan returns the channel for actions published by Record
	Chan() <-chan Action

func NewRecorderStream

func NewRecorderStream() Recorder

type RecorderBuffered

type RecorderBuffered struct {
	// contains filtered or unexported fields

RecorderBuffered appends all Actions to a slice

func (*RecorderBuffered) Action

func (r *RecorderBuffered) Action() []Action

func (*RecorderBuffered) Chan

func (r *RecorderBuffered) Chan() <-chan Action

func (*RecorderBuffered) Record

func (r *RecorderBuffered) Record(a Action)

func (*RecorderBuffered) Wait

func (r *RecorderBuffered) Wait(n int) (acts []Action, err error)
