How to resolve “You have not started an Objectify context” in JUnit?

Question

I\'ve got some Objectify test code running in JUnit and I\'m getting this error:

java.lang.IllegalStateException: You have not started an Objectify context.

Jeff Schnitzer answered this here: https://groups.google.com/forum/#!topic/objectify-appengine/8HinahG7irg. That link points to https://groups.google.com/forum/#!topic/objectify-appengine/O4FHC_i7EGk where Jeff suggests the following quick and dirty workaround:

• My @BeforeMethod starts an objectify context (ObjectifyService.begin())

• My @AfterMethod closes the objectify context

Jeff suggests we use ObjectifyService.run() instead but admits it's more work.

Here's how my implementation looks:

public class DownloadTaskRepositoryImplTest {
    // maximum eventual consistency (see https://cloud.google.com/appengine/docs/java/tools/localunittesting)
    private final LocalServiceTestHelper helper =
        new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig()
            .setDefaultHighRepJobPolicyUnappliedJobPercentage(100));

    private Closeable closeable;

    @Before
    public void setUp() {
        helper.setUp();
        ObjectifyRegistrar.registerDataModel();
        closeable = ObjectifyService.begin();
    }

    @After
    public void tearDown() {
        closeable.close();

        helper.tearDown();
    }
