Subject [jira] (SUREFIRE-952) Incompatibility with future release 4.12 of junit (Categories)
Date Thu, 31 Jan 2013 19:37:13 GMT


Andreas Gudian commented on SUREFIRE-952:

First of all, thanks for the example. But I still don't really get what the remaining problem

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,
* 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 ;).

>From where I'm standing, I see no action to take in Surefire. Did I miss something? Do
you have an other opinion?

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. :)

> 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 (
Unfortuneately the version seems to be incompatible.

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
