=== Background ===
- We want to use Mockito in our tests for Scout RT (Bug 409461).
- Mockito relies on hamcrest and objenesis and is distributed as fat jar distribution (mockito-all-1.9.5.jar) or as separate-jars distribution (mockito-core-1.9.5.jar + hamcrest.core-1.1.0.jar and objenesis-1.0.0.jar)
- Approved CQ 7600 allows to use mockito-core-1.9.5
- Thanks to Stephan Leicht mockito-core-1.9.5 is already available in Orbit: org.mockito_1.9.5.201306061252.jar (Integration build).
=== Problem ===
It is not possible to use the Orbit mockito, hamcrest and objenesis Bundles together in a tycho build.
See the Maven stack trace at the end of this message.
=== Possible solution ===
- Create a new bundle org.eclipse.scout.mockito-all, containing:
* mockito-core-1.9.5.jar from mockito.org (Corresponding to the CQ 0000)
* org.hamcrest.core_1.1.0.v20090501071000.jar from Eclipse Orbit
* org.objenesis_1.0.0.v201105211943.jar from Eclipse Orbit
- org.eclipse.scout.mockito-all isn't in any scout feature, it will not be distributed from the Scout project to the outside (exactly like test fragments).
- all tests fragments that requires mockito declare an additional bundle dependency
- org.eclipse.scout.mockito-all is built with the "testing-build" profile of the Scout RT build.
I have pushed this solution on my feature branch. features/jbr/mockito_bug409461
Content of the org.eclipse.scout.mockito-all Bundle:
org.eclipse.scout.mockito-all

=== Side Note 1 ===
I have tried to use the mockito version from orbit:
org.mockito-1.9.5.v201311280930.jar instead of mockito-core-1.9.5.jar
This should be the same, but with the version from Orbit, I get:
Caused by: java.lang.SecurityException: class "org.eclipse.scout.rt.client.ui.basic.cell.ICellObserver$$EnhancerByMockitoWithCGLIB$$d9869715"'s signer information does not match signer information of other classes in the same package
According to this stackoverflow question: Java SecurityException : signer information does not match, there is a problem with the cglib library.
If I unsign the Orbit jar, the SecurityException is gone.
=== Side Note 2 ===
As pointed out by Markus Keller (Bug 403676#c2) a good move could be to fix the hamcrest dendency problem in the mockito project itself.
This is something that is discussed on the mockito google group, and they have open issues that goes in this direction (for a version 2 of mockito).
=== Maven stack trace ===
Maven stacktrace if the Orbit bundle org.mockito-1.9.5.v201311280930.jar is in the target platform, without the proposed org.eclipse.scout.mockito-all bundle.

In the maven build mockito core works together with hamcrest.core and org.objenesis with the latest osgi (luna), e.g. :
<dependencies>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>1.9.5</version>
</dependency>
<dependency>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
<version>1.4</version>
</dependency>
</dependencies>
<repositories>
<repository>
<!-- Testing with Luna OSGi version -->
<id>Testing</id>
<layout>p2</layout>
<url>url to osgi from luna</url>
</repository>
</repositories>
However, if the tests are run in eclipse, the tests do not run, even if all necessary bundles are available.
Therefore we use mockito.all for the moment, even, if there might be problems with some hamcrest classes.
