Testing for filters.py

Hello Everyone!

I hope you are all doing well!

Description

I wrote tests for filters.py. I also added a fixture that generates per_id of job_listings, hopefully the code and comments are clear enough on that one. I tried to isolate all testing units as much as I could from each other. List any developers that will be affected or those who you had merge conflicts with.
