Class InProcessServerBuilder

java.lang.Object
io.grpc.ServerBuilder<InProcessServerBuilder>
io.grpc.ForwardingServerBuilder<InProcessServerBuilder>
io.grpc.inprocess.InProcessServerBuilder
@ExperimentalApi("https://github.com/grpc/grpc-java/issues/1783") public final class InProcessServerBuilder extends ForwardingServerBuilder<InProcessServerBuilder>
Builder for a server that services in-process requests. Clients identify the in-process server by its name.

The server is intended to be fully-featured, high performance, and useful in testing.

Using JUnit TestRule

The class "GrpcServerRule" (from "grpc-java/testing") is a JUnit TestRule that creates a InProcessServer and a ManagedChannel. This test rule contains the boilerplate code shown below. The classes "HelloWorldServerTest" and "HelloWorldClientTest" (from "grpc-java/examples") demonstrate basic usage.

Usage example

Server and client channel setup

  String uniqueName = InProcessServerBuilder.generateName();
  Server server = InProcessServerBuilder.forName(uniqueName)
      .directExecutor() // directExecutor is fine for unit tests
      .addService(/* your code here */)
      .build().start();
  ManagedChannel channel = InProcessChannelBuilder.forName(uniqueName)
      .directExecutor()
      .build();

Usage in tests

The channel can be used normally. A blocking stub example: 
  TestServiceGrpc.TestServiceBlockingStub blockingStub =
      TestServiceGrpc.newBlockingStub(channel);
