[jira] [Commented] (MAHOUT-1356) Ensure unit tests fail fast when writing outside mvn target directory

["Isabel Drost-Fromm (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-1356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13821886#comment-13821886 ] 

Isabel Drost-Fromm commented on MAHOUT-1356:
--------------------------------------------

Currently all unit tests seem fine when run in parallel mode - no more directory or naming clashes. In order to stop random test failures in the future I would like to see tests fail fast in case they write to some system-global directory - even if that is called /tmp.

One thing to look into in the long run: Configure our surefire to complain when tests mis-behave and store data outside of maven's target directories. Some related documentation and examples so I don't forget it when closing the browser window:

https://svn.apache.org/repos/asf/commons/proper/lang/trunk/src/test/resources/java.policy

http://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html


First (still failing) try attached soon.
