### Question:
JPAEdmAssociationSet extends JPAEdmBaseViewImpl implements JPAEdmAssociationSetView { @Override public JPAEdmBuilder getBuilder() { if (builder == null) { builder = new JPAEdmAssociationSetBuilder(); } return builder; } JPAEdmAssociationSet(final JPAEdmSchemaView view); @Override JPAEdmBuilder getBuilder(); @Override List<AssociationSet> getConsistentEdmAssociationSetList(); @Override AssociationSet getEdmAssociationSet(); @Override Association getEdmAssociation();  }### Answer:
@Test public void testGetBuilder() { assertNotNull(objJPAEdmAssociationSet.getBuilder()); }
@Test public void testGetBuilderIdempotent() { JPAEdmBuilder builder1 = objJPAEdmAssociationSet.getBuilder(); JPAEdmBuilder builder2 = objJPAEdmAssociationSet.getBuilder(); assertEquals(builder1.hashCode(), builder2.hashCode()); }
