[jira] [Commented] (SOLR-3430) DIH: More-realistic testing &
subsequent bug fix
[ https://issues.apache.org/jira/browse/SOLR-3430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268162#comment-13268162 ]
Mikhail Khludnev commented on SOLR-3430:
----------------------------------------
James,
I agree that DB is better than Mock. I'd like to confirm that this approach covers query repetitions issues too. In SOLR-3360 we had a bug when the same query runs many times. Blind automated tests with in-memory DB won't cover such bugs - it will just run same sql 10 times w/o any problems. Will we have a kind of utility wrapper prevents same query run again and again?
Regards

> A couple of people have mentioned on the users' list that 3.6 changes break CachedSqlEntityProcessor. Part of the problem is the current DIH tests are not realistic: they mostly test 1 class at a time and not the full end-to-end interactions between components.
> This is a test of (Cached) SqlEntityProcessor using an in-memory Derby database. This hopefully is a first step in creating a series of new, more-rigorous DIH tests, which is needed in order to make changes without worry.
> This also revealed a bug in SortedMapBackedCache, which is fixed also. I'm not sure this is the same bug causing problems for the 2 users but once committed I will post a reply on the users' list to see if they can try it.
