Steve Loughran commented on HADOOP-4901:
----------------------------------------
I've played with both of these. In some ways I prefer testng to junit4. Junit4
is a better drop-in for the ant tasks, though reporting through <junit> is a
bit degraded. Someone -and it would probalby end up being me- would have to
improve things there by having a separate antlib for junit4 that is java5+ only.
TestNG has a very complex interdependency system, all configured from XML. Its
powerful, but can get a bit confusing, and some people are against it because
its ordering stops tests being independent. I think that's a unit test purist
opinion. What they do have is some data-driven testing where a CSV file drives
the same method with different parameters; this could be interesting.
Both of them treat functional testing of a system cluster as a bit of an
afterthought, as do the standard XML->HTML reports. I've done lots of work in
testing smartforg by using it as a functional test runner itself: deploying
tests and collecting the results. That is also something hadoop's functional
tests could do, feeding the results back into the DFS for later analysis.
> Upgrade to JUnit 4
> ------------------
>
> Key: HADOOP-4901
> URL: https://issues.apache.org/jira/browse/HADOOP-4901
> Project: Hadoop Core
> Issue Type: Improvement
> Components: test
> Reporter: Tom White
> Assignee: Tom White
>
> 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.
