Nigel Daley commented on HADOOP-4901:
-------------------------------------
Or should we consider TestNG? It would be nice to be able to categorize tests
into 1 or more categories (smoke, nightly, dfs, mapred, etc). Not sure JUnit 4
can do this, but TestNG can.
On the other hand, TestNG seems to lack the nice console output controls that
JUnit provides.

> 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.
