Types

type Client

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

Client is a fake implementation of an xds client. It exposes a bunch of channels to signal the occurrence of various events.

func NewClient

func NewClient() *Client

NewClient returns a new fake xds client.

func NewClientWithName

func NewClientWithName(name string) *Client

NewClientWithName returns a new fake xds client with the provided name. This is used in cases where multiple clients are created in the tests and we need to make sure the client is created for the expected balancer name.

func (*Client) Close

func (xdsC *Client) Close()

Close closes the xds client.

func (*Client) InvokeWatchClusterCallback

func (xdsC *Client) InvokeWatchClusterCallback(update xdsclient.CDSUpdate, err error)

InvokeWatchClusterCallback invokes the registered cdsWatch callback.

func (*Client) InvokeWatchEDSCallback

func (xdsC *Client) InvokeWatchEDSCallback(update *xdsclient.EDSUpdate, err error)

InvokeWatchEDSCallback invokes the registered edsWatch callback.

func (*Client) InvokeWatchServiceCallback

func (xdsC *Client) InvokeWatchServiceCallback(cluster string, err error)

InvokeWatchServiceCallback invokes the registered service watch callback.

func (*Client) Name

func (xdsC *Client) Name() string

Name returns the name of the xds client.

func (*Client) ReportLoad

func (xdsC *Client) ReportLoad(server string, clusterName string, loadStore lrs.Store) (cancel func())

ReportLoad starts reporting load about clusterName to server.

func (*Client) WaitForCancelClusterWatch

func (xdsC *Client) WaitForCancelClusterWatch() error

WaitForCancelClusterWatch waits for a CDS watch to be cancelled within a reasonable timeout, and returns testutils.ErrRecvTimeout otherwise.

func (*Client) WaitForClose

func (xdsC *Client) WaitForClose() error

WaitForClose waits for Close to be invoked on this client within a reasonable timeout, and returns testutils.ErrRecvTimeout otherwise.

func (*Client) WaitForReportLoad

func (xdsC *Client) WaitForReportLoad() (ReportLoadArgs, error)

WaitForReportLoad waits for ReportLoad to be invoked on this client within a reasonable timeout, and returns the arguments passed to it.

func (*Client) WaitForWatchCluster

func (xdsC *Client) WaitForWatchCluster() (string, error)

WaitForWatchCluster waits for WatchCluster to be invoked on this client within a reasonable timeout, and returns the clusterName being watched.

func (*Client) WaitForWatchEDS

func (xdsC *Client) WaitForWatchEDS() (string, error)

WaitForWatchEDS waits for WatchEndpoints to be invoked on this client within a reasonable timeout, and returns the clusterName being watched.

func (*Client) WaitForWatchService

func (xdsC *Client) WaitForWatchService() (string, error)

WaitForWatchService waits for WatchService to be invoked on this client within a reasonable timeout, and returns the serviceName being watched.

func (*Client) WatchCluster

func (xdsC *Client) WatchCluster(clusterName string, callback func(xdsclient.CDSUpdate, error)) func()

WatchCluster registers a CDS watch.

func (*Client) WatchEndpoints

func (xdsC *Client) WatchEndpoints(clusterName string, callback func(*xdsclient.EDSUpdate, error)) (cancel func())

WatchEndpoints registers an EDS watch for provided clusterName.

func (*Client) WatchService

func (xdsC *Client) WatchService(target string, callback func(xdsclient.ServiceUpdate, error)) func()

WatchService registers a LDS/RDS watch.

type ReportLoadArgs

type ReportLoadArgs struct {
	// Server is the name of the server to which the load is reported.
	Server string
	// Cluster is the name of the cluster for which load is reported.
	Cluster string
}

ReportLoadArgs wraps the arguments passed to ReportLoad.
