i would like to know if it is possible to create a test fixture that will run a series test on PCB's and is controlled by an arduino uno
Yes, it's possible.
You might find this interesting:
BTW, using a title appropriate to the topic of your post is a good idea. Yours is definitely not unless you really only want answers from Nick Gammon, who was last seen on this forum >3 weeks ago.
If you edit your Original Post you can change the title to describe what you want help with - perhaps "How to create PCB test fixture"
