Parameterized runner should name tests better than sequential numbers about junit4

[JThoennes]

How about this issue? The suggestions are good, when will you implement it / incorporate the patch?

Thanks, Jörg

See also issue 24 which talks about the same topic, but was entered by dsaff.

Any more news on when this fix might be implemented?

There appears to be some demand for this simple feature outside as well: http://stackoverflow.com/questions/650894/change-test-name-of-parameterized-tests

As an additional (simpler) suggestion, how about just changing
@OverRide protected String testName(final FrameworkMethod method) {
return String.format("%s%s", method.getName(),
Arrays.toString(fParameterList.get(fParameterSetNumber)));
}

From my deployment experience (I forked Parameterized internally to my project and extended it with similar functionality), using toString or non-static testName() functions were suboptimal, and using a fixed portion of the parameters list (either the first parameter or all of them) was also not useful. My preferred solution was to support an annotated static method that took the same arguments as the constructor and returned a string, and fall back to the test number if that didn't work.

I'm happy to get the (fairly trivial) patch open sourced if that would help solve this problem.

Thanks,

Could this patch merged into the next JUnit release, please?

And when will the next release happen?

I have released a framework that offers a solution to this problem:
http://callbackparams.org The test-class runner that will probably solve most cases where this problem arises is ...
http://callbackparams.org/project/api-javadoc/org/callbackparams/junit4/EnumRunner.html ... and for more complex cases the rest of the framework has a lot to offer.

The key feature in regard to this issue is that tests are named by the overridden method java.lang.Object#toString(), which for enum-constants happen to return the name of the constant. If the enum-constant name won't do it is of course still possible to override java.lang.Object#toString() explicitly for those constants that need more verbose test-names.

Anyhow, I think that a solution that does not rely on the toString()-method is simply not very elegant.

Cmon! Why can't you apply this Kent? You even have ready patches and the issue is ancient. Isn't good naming part of cleancode and TDD practices - or do we simply have to dump junit for testng?

I like Dave's idea of a label method. It may look like

@Label
public String labelForParameters(Object... parameters) {
  ...
}

Hopefully there's time today or tomorrow evening to implement this.

+1. We've started keeping our own version of Parameterized to fix this problem, but it would be great to have this supported from the source.

+1 we have used a fork of Parameterized to implement this feature. We have also made the TestClassRunnerForParameters protected, and it is created by a protected method to allow extension of Parameterized within another implementation of Suite.

[stefanbirkner]

The feature is implemented. See #393.

@dsaff Could you please close the issue.

[dsaff]

Done.

[java-artisan]

Many thanks indeed ! :-)
