How to test function for new entry hook?

[manueldeljesus]

Dear Chris:

I am in the process of learning Elisp and have thought to implement a content tweaking function to be able to read Dilbert's rss in elfeed. I would like to program a function to change the contents of the feed, downloading the web contents from the link that appears in the header of the rss entry.

However, I do not know how to test the function. I would like to know how may I get entries, even the ones in the database, to test my function. I am not sure on what kind of data or structure the elfeed functions return, so I would really appreciate if you could point me towards a way to analyze the values returned by the different functions.

Your help will be much appreciated.
