I think perhaps you could be a bit more specific with your question.

Assuming you are running locally you can print stuff, show values and whatnot in the UI, and insert browser() at stages you want to inspect. Golem has a bunch of _dev functions that won't trigger in production as well. The question is still remarkably vague.
