Please can you help me writing junits for below method,
public Map<String, List<Entity>> getEntitiesUsingAncestorKey(Key ancestorKey) {
QueryResults<Entity> queryResults;
StringBuffer queryString = new StringBuffer();
queryString.append("SELECT * WHERE __key__ HAS ANCESTOR @ancestorKey");
Query<Entity> query = Query.newGqlQueryBuilder(Query.ResultType.ENTITY, queryString.toString())
.setBinding("ancestorKey", ancestorKey)
.build();
queryResults = datastore.run(query);
return StreamSupport.stream(
Spliterators.spliteratorUnknownSize(queryResults, Spliterator.ORDERED), false)
.collect(Collectors.groupingBy(entity -> entity.getKey().getKind()));
}
How to mock QueryResults..?
