[jira] [Commented] (OAK-3251) speeding up the build time

["Davide Giannella (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-3251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14702675#comment-14702675 ] 

Davide Giannella commented on OAK-3251:
---------------------------------------

When running a simple clean install, only the SEGMENT_MK is passed as
fixture. A first quick win I can thing by looking at the tests
namespaces is to adopt the {{FixtureHelper}} in

- org.apache.jackrabbit.oak.plugins.document.VersionGarbageCollectorTest
- org.apache.jackrabbit.oak.plugins.document.BasicDocumentStoreTest

by having them running only for {{DOCUMENT_*}} fixtures. This will
speed up a clean install already by roughly one minute.

On the other hand for speeding up the builds Fixtures oriented builds
on jenkins we could limit to {{SEGMENT_MK}} fixtures the tests

- org.apache.jackrabbit.oak.plugins.segment.SegmentDataStoreBlobGCTest
- org.apache.jackrabbit.oak.plugins.segment.file.FileStoreTest
- org.apache.jackrabbit.oak.plugins.segment.ExternalBlobTest
- org.apache.jackrabbit.oak.plugins.segment.CompactionAndCleanupTest

having therefore a build for {{DOCUMENT_*}} roughly 2 minutes faster.

Thoughts?
