Chris Hansen commented on SUREFIRE-1055:
----------------------------------------
@Tibor
Thank you for the suggestion. It is something I had tried using
System.out.println(...) prior to submitting a bug. However, just now I was able
to get a consistent test count by writing the count to a file in a shutdown
hook. That means you are correct that the tests are being run, and there is a
logging issue. I think System.out.println() output is subject to the same
logging issue in question, which is why I hadn't gotten a consistent count
previously.
Is there an existing Jira issue for this (in which case I can close this one)
or shall I change this issue to describe the logging bug?
Also, thank you for your work on SUREFIRE-814, Tibor.

> Key: SUREFIRE-1055
> URL: https://jira.codehaus.org/browse/SUREFIRE-1055
> Project: Maven Surefire
> Issue Type: Bug
> Components: Junit 4.7+ (parallel) support, Maven Failsafe Plugin,
> Maven Surefire Plugin
> Affects Versions: 2.16
> Reporter: Chris Hansen
> Attachments: surefire-output.txt
>
>
> Some test methods are skipped at random with the below configuration. When
> test methods are skipped in this way, only one method in the class runs.
> Running tests repeatedly with no code change often yields a different number
> of tests with each run (e.g. see the attached surefire-output.txt). Tests
> that take longer to run are less likely to be affected. This affects version
> 2.16 of Surefire and Failsafe equally.
> Here is a simple test project which reproduces the issue:
> https://github.com/hansenc/SUREFIRE-1055
> It has a few simple test classes with a naming convention for how many test
> methods are in each class (e.g. Methods4Test has 4 test methods).
