This is what works for me:

<?xml version="1.0"?>
<module>
  <!-- Define a location for storing dojo modules. The "path" value is relative to the ClientResources physical folder. The "name" value acts as an alias for that location. -->
  <dojoModules>
    <add name="app" path="Scripts" />
  </dojoModules>
</module>

Then if you are using this for something like an editor descriptor, it would look like this:

ClientEditingClass = "app/Editors/MyEditor;

And the path to that dojo module would be at "/ClientResources/Scripts/Editors/MyEditor.js"

Thanks, that gave me a tip and with this settings it works:

<?xml version="1.0" encoding="utf-8"?>
<module>  	
	<clientModule initializer="Testing/Initializer">
		<moduleDependencies>
			<add dependency="CMS" type="RunAfter" />
		</moduleDependencies>
	</clientModule>
  <dojo>
    <paths>
      <add name="Testing" path="Scripts" />
    </paths>
  </dojo>
</module>

Just removed ClientResources from path. I think I tried that but probably not...

Thanks again!
