------------------------------------------------------------------
Some of the options are not available on 2.15 and below, but I've tried some
different configuration combinations and have not been to reproduce this issue
with 2.15. Also, I've tried different configuration combinations with 2.16 and
I've only seen this issue when parallel=classesAndMethods or parallel=all with
the rest of the above configuration.

> 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).
