Ondrej Zizka created SUREFIRE-808:
-------------------------------------
Summary: Selectable "grouping mode" for test groups - UNION or
INTERSECTION.
Key: SUREFIRE-808
URL: https://jira.codehaus.org/browse/SUREFIRE-808
Project: Maven Surefire
Issue Type: Improvement
Components: Junit 4.7+ (parallel) support, Junit 4.x support
Affects Versions: 2.11, 2.10
Reporter: Ondrej Zizka
Currently, the `groups` and `excludedGroups` work like:
{code}
( include1 OR include2 ... ) AND NOT ( exclude1 OR exclude2 OR ... )
{code}
This doesn't cover many usecases. For instance, if the groups overlap.
Example: user needs to run only EJB tests under security manager, while only
some EJB tests can run under security manager.
In such case, this is needed:
{code}
( EJB AND SecurityManager )
{code}
The suggestion is to introduce two new params:
{code}
groupingMode = union|intersection
excludeGroupingMode = union|intersection
{code}
They would switch AND and OR behavior.
Union would be the default (preserving current behavior).
Would be implemented in a filter, see:
