Functions

func RegisterServiceServerOption

func RegisterServiceServerOption(f func(*grpc.Server)) grpc.ServerOption

RegisterServiceServerOption returns a ServerOption that will run f() in Start or StartServer with the grpc.Server created before serving. This allows other services to be registered on the test server (e.g. ORCA, health, or reflection).

Types

type StubServer

type StubServer struct {
	// Guarantees we satisfy this interface; panics if unimplemented methods are called.
	testgrpc.TestServiceServer

	// Customizable implementations of server handlers.
	EmptyCallF      func(ctx context.Context, in *testpb.Empty) (*testpb.Empty, error)
	UnaryCallF      func(ctx context.Context, in *testpb.SimpleRequest) (*testpb.SimpleResponse, error)
	FullDuplexCallF func(stream testgrpc.TestService_FullDuplexCallServer) error

	// A client connected to this service the test may use.  Created in Start().
	Client testgrpc.TestServiceClient
	CC     *grpc.ClientConn
	S      *grpc.Server

	// Parameters for Listen and Dial. Defaults will be used if these are empty
	// before Start.
	Network string
	Address string
	Target  string

	// Set automatically if Target == ""
	R *manual.Resolver
	// contains filtered or unexported fields
}

StubServer is a server that is easy to customize within individual test cases.

func StartTestService

func StartTestService(t *testing.T, server *StubServer) *StubServer

StartTestService spins up a stub server exposing the TestService on a local port. If the passed in server is nil, a stub server that implements only the EmptyCall and UnaryCall RPCs is started.

func (*StubServer) EmptyCall

func (ss *StubServer) EmptyCall(ctx context.Context, in *testpb.Empty) (*testpb.Empty, error)

EmptyCall is the handler for testpb.EmptyCall

func (*StubServer) FullDuplexCall

func (ss *StubServer) FullDuplexCall(stream testgrpc.TestService_FullDuplexCallServer) error

FullDuplexCall is the handler for testpb.FullDuplexCall

func (*StubServer) NewServiceConfig

func (ss *StubServer) NewServiceConfig(sc string)

NewServiceConfig applies sc to ss.Client using the resolver (if present).

func (*StubServer) Start

func (ss *StubServer) Start(sopts []grpc.ServerOption, dopts ...grpc.DialOption) error

Start starts the server and creates a client connected to it.

func (*StubServer) StartClient

func (ss *StubServer) StartClient(dopts ...grpc.DialOption) error

StartClient creates a client connected to this service that the test may use. The newly created client will be available in the Client field of StubServer.

func (*StubServer) StartServer

func (ss *StubServer) StartServer(sopts ...grpc.ServerOption) error

StartServer only starts the server. It does not create a client to it.

func (*StubServer) Stop

func (ss *StubServer) Stop()

Stop stops ss and cleans up all resources it consumed.

func (*StubServer) UnaryCall

UnaryCall is the handler for testpb.UnaryCall
