Subject [jira] Commented: (HADOOP-4901) Upgrade to JUnit 4
Date Fri, 29 May 2009 16:44:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714502#action_12714502

Philip Zeyliger commented on HADOOP-4901:
-----------------------------------------

I believe one of our goals is to be able to "label" tests as "smoke", "fast", "slow", etc.
 One way to approach this, even with JUnit3, is to use Java annotations, and then query for
them with something like http://developer.android.com/reference/android/test/suitebuilder/TestSuiteBuilder.html
.  We could easily cook up something similar.

> 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.
