[jira] [Commented] (OAK-856) Use in-memory MongoMK instead of MicroKernelImpl for tests

["Thomas Mueller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13675823#comment-13675823 ] 

Thomas Mueller commented on OAK-856:
------------------------------------

There seem to be a few issues to be fixed before switching.

The following oak-core test failure seems to be related to branch/merge in the MongoMK:
{code}
rebaseWithMove(org.apache.jackrabbit.oak.core.RootImplTest): expected:<2> but was:<3>
rebaseWithCopy(org.apache.jackrabbit.oak.core.RootImplTest): expected:<3> but was:<4>
{code}

Also, org.apache.jackrabbit.oak.core.TreeImplTest#largeChildList failed for me with "Java heap space" error; this might be related to the background thread in the MongoMK that keeps a reference to the storage (the tests don't dispose the MicroKernel; there is no dispose method).

> Currently, most tests are run against the (in-memory) MicroKernelImpl.
> To improve test coverage of the MongoMK, we should use the MongoMK instead by default.
