I got a 15 gallon plastic barrel for free from one of my customers at work who owns a pressure washing business. I want to use it for storing ro/di water. He stored sodium hypochlorite in it which I believe is bleach. Is it safe to use? Can I test it somehow?

Let it sit completely dry for a day or two and it will be fine. Sodium hypochlorite is not stable when it is dry and will go away pretty quick. Rinse it good with water afterwards.

+1. As long as the plastic is fine for water storage the bleach will go away after that treatment. And when you are done with the water rinse give it the sniff test.

Okay cool so I'm guessing since it has been sitting dry for about three months I would be sa safe just to rinse it out and use it?

If the plastic is OK, should be fine.

What do you mean by the plastic being okay? Do you mean like dry rotted or something?

No, just some people are uncomfortable holding anything long term in things not rated for drinking water because of the fear it would leach chemicals (like if it had a bactericide in it or something of that nature). Its probly fine, but if you can confirm what it was made of it'd be ideal.

I might add some vinegar to the rinse, to help dissolve or remove anything that's remaining the container, but it likely is fine. I tend to stick to food-grade containers, though, personally.
