How to see a file content in shrinkWrap
Put the part reported below in your arquillian.xml, as described in the guide. This way you will be able to browse deployed test archive. ShrinkWrap on its own does not provide such inspection feature.
This is the XML you should add to your arquillian.xml file:
<engine>
<property name="deploymentExportPath">target/deployments</property>
</engine>
