Building a XPages App with Maven and running Junit Tests - maven

Question

I have an Domino XPages Application which is already built from an OnDiskProject into an .nsf by maven.
The pom.xml for that step is ok and running.
Now, I wanted to include the maven-surefire-plugin (or any other) to execute the Junit Tests. But maven told me, that there are no tests found.
I use the Packaging Type domino-nsf from frostillic.us, which works fine for compiling and deploying.
The plugin definition is as follows:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12.4</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit4</artifactId>
<version>2.8</version>
</dependency>
</dependencies>
<executions>
<execution>
<id>test</id>
<phase>test</phase>
<configuration>
<includes>
<include>**/*Test.java</include>
</includes>
</configuration>
<goals>
<goal>test</goal>
</goals>
</execution>
</executions>
</plugin>
We use the https://www.openntf.org/main.nsf/project.xsp?r=project/org.openntf.junit.xsp plugin to develop tests. The tests are running in the browser with no problem (calling an Xpage with Junit tests).
May be I have to create a separate module for testing, but I did not have success with that approach. Any help or hints are appreciated and welcome.
I tried it with the maven-surefire-plugin and also with tycho-surefire-plugin. But both didn't work. The tycho-surefire-plugin don't work with the domino-nsf packaging type.
Update:
Here is the complete pom.xml:
