body: <p>I am using Google Cloud Storage (GCS) in my GAE application. For that I wrote some JUnits to test functionality that is dependent on the GCS.

  <p>Earlier I used Blobstore using Google FileService API. But FileService API is deprecated, so that I moved to GCS and using GcsService API. For Blobstore Junits I used -</p>
  
  <pre><code>private final LocalServiceTestHelper blobStoreHelper =
      new LocalServiceTestHelper(new LocalBlobstoreServiceTestConfig());
  </code></pre>
