Konstantin Boudnik commented on HADOOP-4901:
--------------------------------------------
Here's a comment on JUnitExt remarks. It seems that JUnit Extension project
supports the categorization of some kind. However, it seems that the semantic
of their @Category is very different from our desire for tagging is. Here's the
excerpt from JUnitExt tutorial:
{panel:title=JUnitExt tutorial's excerpt}
How to use categories
Tests can be categorized, to sort them for different puporses. JUnitExt
provides a CategoryTextListerner, which prints out at end of test run all
categories, with status of tests listed: May be Success, Ignored, Failed. You
can plugin the category text listener using following code: (see also
org.junitext.samples package)
JUnitCore core = new JUnitCore();
// use for categories special listener, give some statistics
core.addListener(new CategoryTextListener(System.out));
core.run(SimpleTest.class);
The output when running thes tests will be:
I.
Time: 0
OK (1 test)
Category: equal tests
Success testEquals(org.junitext.samples.SimpleTest)
Category: math tests
Ignored divideByZero(org.junitext.samples.SimpleTest)
{panel}
It might be possible to extend or develop new ClassRunner which will be capable
of running only tests from a specified @Category, however it isn't provided by
JUnitExt out of the box or the documentation fails no mention it.
> Upgrade to JUnit 4
> ------------------
>
> Key: HADOOP-4901
> URL: https://issues.apache.org/jira/browse/HADOOP-4901
> Project: Hadoop Common
> Issue Type: Improvement
> Components: test
> Reporter: Tom White
> Assignee: Alex Loddengaard
>
> 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.
