Peter Lynch created SUREFIRE-917:
------------------------------------
Summary: [junit] category simple name matching fails throwing
ClassNotFoundException
Key: SUREFIRE-917
URL: https://jira.codehaus.org/browse/SUREFIRE-917
Project: Maven Surefire
Issue Type: Bug
Components: Junit 4.x support
Affects Versions: 2.12.4
Reporter: Peter Lynch
Attachments: fix_support_for_junit_simple_group_name_matching.patch
According to a [unit test I
found|https://git-wip-us.apache.org/repos/asf?p=maven-surefire.git;a=blob;f=surefire-grouper/src/test/java/org/apache/maven/surefire/group/parse/GroupMatcherParserTest.java;h=e92595a09de1eb706f54c70b8efe8df592e40ec5;hb=HEAD#l134]
JUnit categories/group support should allow matching groups by the category
interface simple name along with the fully qualified name.
Example , given category interfaces:
{noformat}
category.Fast
category.Slow
{noformat}
The following commands should be equivalent:
{noformat}
mvn test -Dgroups="Slow,Fast"
mvn test -Dgroups="category.Slow,category.Fast"
mvn test -Dgroups="category.Slow.class,category.Fast.class"
{noformat}
In my testing, the first command does not work. Instead I get the following
exception:
{noformat}

{noformat}
It seems like if a category name cannot be loaded, it should just be ignored.
I added an integration test that proves the failure and supplied a patch which
avoids the problem to allow specifying the simple class name for matching.
It would be great to have this working to allow a developer to easily run
specific groups of tests in a concise manner.
