### Question:
EdmAssociationSetImplProv extends EdmNamedImplProv implements EdmAssociationSet, EdmAnnotatable { @Override public EdmAssociation getAssociation() throws EdmException { EdmAssociation association = edm.getAssociation(associationSet.getAssociation().getNamespace(), associationSet.getAssociation().getName()); if (association == null) { throw new EdmException(EdmException.COMMON); } return association; } EdmAssociationSetImplProv(final EdmImplProv edm, final AssociationSet associationSet,
      final EdmEntityContainer edmEntityContainer); @Override EdmAssociation getAssociation(); @Override EdmAssociationSetEnd getEnd(final String role); @Override EdmEntityContainer getEntityContainer(); @Override EdmAnnotations getAnnotations();  }### Answer:
@Test public void testAssociationExists() throws Exception { EdmAssociationSet associationSet = edmAssociationSet; assertNotNull(associationSet.getAssociation()); }
