### Question:
JPAEdmSchema extends JPAEdmBaseViewImpl implements JPAEdmSchemaView { @Override public void clean() { super.clean(); schema = null; } JPAEdmSchema(final JPAEdmModelView modelView); @Override Schema getEdmSchema(); @Override JPAEdmEntityContainerView getJPAEdmEntityContainerView(); @Override JPAEdmComplexTypeView getJPAEdmComplexTypeView(); @Override JPAEdmBuilder getBuilder(); @Override void clean(); @Override final JPAEdmAssociationView getJPAEdmAssociationView(); @Override void registerOperations(final Class<?> customClass, final String[] methodNames); @Override HashMap<Class<?>, String[]> getRegisteredOperations();  }### Answer:
@Test public void testClean() { assertTrue(objJPAEdmSchema.isConsistent()); objJPAEdmSchema.clean(); assertFalse(objJPAEdmSchema.isConsistent()); }
@Test public void testIsConsistent() { assertTrue(objJPAEdmSchema.isConsistent()); objJPAEdmSchema.clean(); assertFalse(objJPAEdmSchema.isConsistent()); }
