Я пытаюсь написать какой-нибудь модульный тест для одного из сервисов GRPC.
Я использую GrpcServerRule для этого.
После запуска теста кажется, что реализация службы загружена неправильно. Мне не удается выяснить, почему.
Вот код для теста.
@RunWith(JUnit4::class)
class CreateListTest {
// Workaround for public
@get:Rule val serverRule: GrpcServerRule = GrpcServerRule().directExecutor()
@Before
fun setup() {
serverRule.serviceRegistry.addService(ShopperServerImplementation())
}
@Test
fun testCreateListValidRequest() {
val request = CreateListRequest.newBuilder()
.setName("a test list")
.setAuthorId(25)
.addAuthorizedUsers(12)
.build()
val reply = ShopperServiceGrpc.newBlockingStub(serverRule.channel).createList(request)
assertEquals(45, reply.createdListId)
}
}
Вот код для реализации сервиса.
class ShopperServerImplementation : ShopperGRPCGrpc.ShopperGRPCImplBase() {
override fun createList(request: CreateListRequest, responseObserver: StreamObserver<CreateListReply>) {
val reply = CreateListReply.newBuilder().setCreatedListId(80).build()
responseObserver.onNext(reply)
responseObserver.onCompleted()
}
}
Вот журнал с результатами теста
