### Question:
GraphProjection implements Queries.Projection { @Override public Queries.Projection includeAttributes(Attribute.Family namespace) { getTerminal().include(namespace); return this; } @Inject  GraphProjection(GraphVisitor repository,
            OperationPipeline aPipeline); @Override Queries.Projection includeAttribute(Attribute.Name name); @Override Queries.Projection includeAttributes(Attribute.Family namespace); @Override Query ready();  }### Answer:
@Test public void testIncludeAttributesFamily(){ GraphVisitor repository = new MockGraphVisitor(); GraphProjection graphProjection = new GraphProjection(repository, new OperationPipeline()); Projection includeAttributes = graphProjection.includeAttributes(TartanImplTestConstants.ATTR_DUMMY_FAMILY); assertNotNull(includeAttributes); }
