Subject [jira] Commented: (HBASE-410) [testing] Speed up the test suite
Date Wed, 14 Oct 2009 20:12:31 GMT

    [ https://issues.apache.org/jira/browse/HBASE-410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765725#action_12765725

stack commented on HBASE-410:
-----------------------------

I'm abandoning attached patch.  Revamping our current test framework is wrong way to go. 
Instead rewrite it all in junit4 spinning up clusters at start and end rather than per test.

> The test suite takes a long time to run, and a lot of the time spent running is really
wasted on repeated startup and shutdown, waiting for asynchronous events to occur, and production-tuned
timeouts to occur. Additionally, we use a MiniDFS instead of the local filesystem. 
> We should:
>  - Make whatever changes are needed to the local DFS so that it can run on Windows and
use that as the basis of all of our tests
>  - Minimize redoing expensive setup where possible by combining tests into groups or
suites that can share common setup
>  - Create a way of running all the parts (Master, Regionserver, Client) in a single thread
and explicitly advancing through necessary states so that we can reliably and quickly get
what we need tested accomplished
>  - Use smaller test datasets where it would make a difference (TestTableIndex and TestTableMapReduce,
I'm looking at you!)
> A faster test suite means faster turnaround on new patches, faster Hudson, and a shorter
patch queue. Not to mention less annoyance on the part of the developers.
