[jira] Commented: (SOLR-2175) DIH needs Mock (or real in-memory) JDBC/Mail impls for tests... especially JDBC

    [ https://issues.apache.org/jira/browse/SOLR-2175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12922594#action_12922594 ] 

Uwe Schindler commented on SOLR-2175:
-------------------------------------

we could bundle HSQLDB for an internal test-only database [if java6, Apache Derby is bundled with the JDK in some cases]. We could then use it to fill a database. Ideally we should simply provide the HSQLDB dump output in the tests/resources folder (which contains of tons of CREATE TABLE, INSERT,...) statements that on-the-fly build the database in memory. After that we run the tests and release the JDBC driver again.

> One way to improve this would be to use something like apache derby for tests to make little databases and test against.
> Additionally, looking thru JIRA there are a lot of JDBC-related issues and once something like this is setup,
> I think things could improve without introducing more bugs.
