public class DatastoreEmulator extends DatastoreAn extension to Datastore that provides lifecycle management for a datastore emulator.

static DatastoreEmulator datastore;
@BeforeClass public static void startEmulator() throws DatastoreEmulatorException { DatastoreOptions options = new DatastoreOptions.Builder() .localHost("localhost:8080") .projectId("my-project-id") .build(); datastore = DatastoreEmulatorFactory.get().create(options); datastore.start("/usr/local/cloud-datastore-emulator", "my-project-id"); }
@Before public void setUp() throws DatastoreEmulatorException { datastore.clear(); }
@AfterClass public static void stopEmulator() throws DatastoreEmulatorException { datastore.stop(); }
@Test public void testFoo1() { }
@Test public void testFoo2() { }
