示例1: testWatchTree

func testWatchTree(t *testing.T, kv store.Store) {
	dir := "testWatchTree"

	node1 := "testWatchTree/node1"
	value1 := []byte("node1")

	node2 := "testWatchTree/node2"
	value2 := []byte("node2")

	node3 := "testWatchTree/node3"
	value3 := []byte("node3")

	err := kv.Put(node1, value1, nil)
	assert.NoError(t, err)
	err = kv.Put(node2, value2, nil)
	assert.NoError(t, err)
	err = kv.Put(node3, value3, nil)
	assert.NoError(t, err)

	stopCh := make(<-chan struct{})
	events, err := kv.WatchTree(dir, stopCh)
	assert.NoError(t, err)
	assert.NotNil(t, events)

	// Update loop
	go func() {
		timeout := time.After(500 * time.Millisecond)
		for {
			select {
			case <-timeout:
				err := kv.Delete(node3)
				assert.NoError(t, err)
				return
			}
		}
	}()

	// Check for updates
	eventCount := 1
	for {
		select {
		case event := <-events:
			assert.NotNil(t, event)
			// We received the Delete event on a child node
			// Exit test successfully
			if eventCount == 2 {
				return
			}
			eventCount++
		case <-time.After(4 * time.Second):
			t.Fatal("Timeout reached")
			return
		}
	}

示例2: testPutGetDeleteExists

func testPutGetDeleteExists(t *testing.T, kv store.Store) {
	// Get a not exist key should return ErrKeyNotFound
	pair, err := kv.Get("testPutGetDelete_not_exist_key")
	assert.Equal(t, store.ErrKeyNotFound, err)

	value := []byte("bar")
	for _, key := range []string{
		"testPutGetDeleteExists",
		"testPutGetDeleteExists/",
		"testPutGetDeleteExists/testbar/",
		"testPutGetDeleteExists/testbar/testfoobar",
	} {
		failMsg := fmt.Sprintf("Fail key %s", key)

		// Put the key
		err = kv.Put(key, value, nil)
		assert.NoError(t, err, failMsg)

		// Get should return the value and an incremented index
		pair, err = kv.Get(key)
		assert.NoError(t, err, failMsg)
		if assert.NotNil(t, pair, failMsg) {
			assert.NotNil(t, pair.Value, failMsg)
		}
		assert.Equal(t, pair.Value, value, failMsg)
		assert.NotEqual(t, pair.LastIndex, 0, failMsg)

		// Exists should return true
		exists, err := kv.Exists(key)
		assert.NoError(t, err, failMsg)
		assert.True(t, exists, failMsg)

		// Delete the key
		err = kv.Delete(key)
		assert.NoError(t, err, failMsg)

		// Get should fail
		pair, err = kv.Get(key)
		assert.Error(t, err, failMsg)
		assert.Nil(t, pair, failMsg)

		// Exists should return false
		exists, err = kv.Exists(key)
