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() { }

}
