Package dev.restate.sdk.testing

Class RestateRunner

  • All Implemented Interfaces:
    org.junit.jupiter.api.extension.BeforeAllCallback, org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.ParameterResolver
    public class RestateRunner
extends java.lang.Object
implements org.junit.jupiter.api.extension.BeforeAllCallback
    Restate runner for JUnit 5. Example: 
    
 {@literal @}RegisterExtension
 private final static RestateRunner restateRunner = RestateRunnerBuilder.create()
         .withService(new MyService())
         .buildRunner();

    The runner will deploy the services locally, execute Restate as container using testcontainers, and register the services.

    This extension is scoped per test class, meaning that the restate runner will be shared among test methods.

    Use the annotations RestateGrpcChannel, RestateURL and RestateAdminClient to interact with the deployed runtime: 

    
 {@literal @}Test
 void testGreet({@literal @}RestateGrpcChannel ManagedChannel channel) {
     CounterGrpc.CounterBlockingStub client = CounterGrpc.newBlockingStub(channel);
     // Use client
 }
