### Question:
BlobPuller implements RegistryEndpointProvider<Void> { @Override public List<String> getAccept() { return Collections.emptyList(); } BlobPuller(
      RegistryEndpointRequestProperties registryEndpointRequestProperties,
      DescriptorDigest blobDigest,
      OutputStream destinationOutputStream,
      Consumer<Long> blobSizeListener,
      Consumer<Long> writtenByteCountListener); @Override Void handleResponse(Response response); @Override @Nullable BlobHttpContent getContent(); @Override List<String> getAccept(); @Override URL getApiRoute(String apiRouteBase); @Override String getHttpMethod(); @Override String getActionDescription(); @Override Void handleHttpResponseException(ResponseException responseException);  }### Answer:
@Test public void testGetAccept() { Assert.assertEquals(0, testBlobPuller.getAccept().size()); }
