Andreas Gudian commented on SUREFIRE-952:
-----------------------------------------
First of all, thanks for the example. But I still don't really get what the
remaining problem is.
This is what I tried with your demo projects (I changed the junit-dependencies
to junit:junit:4.12-SNAPSHOT and removed the junitArtifactName-property):
* Groups and excludedGroups work as expected with the dummy test class and the
@Category annotation on the super class. *No problem observed* (Which is what
you meant with your first comment, right?)
* Leaving the groups-setting in the parent pom, but removing the
junit-dependency in the module that does not contain any tests worked as
expected (no tests were executed, no error was shown). *No problem observed*
So, I did some digging into the code and tried around a bit more: When using
groups/excludedGroups, the artifacts of either {{testNGArtifactName}} or
{{junitArtifactName}} (manually overwritten or default values) need to be on
the classpath. Surefire will ignore that only if not "target/test-classes"
directory was created by the build, which is typically the case when you have
nothing within your src/test/java directory. That sounds somewhat reasonable to
me, I guess it is not in violation of the documentation, and it is not that
hard to accomplish (in my project, when I configure surefire in a parent pom, I
also add the test-scope dependency for junit right away). So, I see *no real
problem* here, too.
I tried Surefire 2.12.2 (what you included in the pom), 2.13 (the current
release) and 2.14-SNAPSHOT (which will be released within the next very few
weeks). I did not try 2.3 - too old for my taste ;).

Btw, since 2.13 we do not try to compute the outcome of the JUnit
{{@Category}}-filtering anymore and leave it to the JUnit implementation
itself. :)
> Incompatibility with future release 4.12 of junit (Categories)

> Key: SUREFIRE-952
> URL: https://jira.codehaus.org/browse/SUREFIRE-952
> Project: Maven Surefire
> Issue Type: Bug
> Components: Junit 4.x support
> Affects Versions: 2.12.2, 2.12.4
> Reporter: Henning Gross
> Priority: Blocker
> Attachments: surefire-952.zip

>
> Junit is introducing some interesting new features on Categories in 4.12.
> @Category will become @Inherited and @ExcludeCategory/@IncludeCategory will
> accept a class-array instead of just a single class. As we need these
> urgently we are currently testing with the current snapshot of junit
> (https://oss.sonatype.org/content/repositories/snapshots/junit/junit/4.12-SNAPSHOT/).
> Unfortuneately the version seems to be incompatible.
> All tests are executed always. Regardless of the settings in <groups> or
> <excludedgroups>. Using 4.11 works fine. I do not know why this happens and
> therefore cannot provide a patch but I would love to see it fixed. If someone
> points me at the cause I will happily find a solution.
