I don't know what you are really looking for so I will tell you two ways to do some debugging:
First one would be in the designer open the interface tool (cntl + alt + d). There on the second tab (magic wand) you will see on the right the "open debug" icon with which you can perform normal debugging.
If you on the other hand want to check the results on the analytic app on different points (after specific tools) you could add a browser to those points and check to see them on the output:
Hope this helps
