Subject [jira] Commented: (HADOOP-4901) Upgrade to JUnit 4
Date Fri, 29 May 2009 17:08:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714514#action_12714514

Konstantin Boudnik commented on HADOOP-4901:

Or we can start using testng to run JUnit tests natively and migrate them to 
'native' TestNG format eventually. There's a couple of benefits which JUnit 
doesn't have. E.g.
   - parallel tests execution
   - sameVM execution (without forking)
   - absence of mandatory TestCase's inheritance which limits the options of 
test developers.

With regards,

> Amongst other things, JUnit 4 has better support for class-wide set up and tear down
(via @BeforeClass and @AfterClass annotations), and more flexible assertions (http://junit.sourceforge.net/doc/ReleaseNotes4.4.html).
It would be nice to be able to take advantage of these features in tests we write.
> JUnit 4 can run tests written for JUnit 3.8.1 without any changes.
