'Are there tools for regression/sanity testing a live website?

At work we're being asked to manually eyeball tableau visualizations to check that they meet a bunch of particular sanity checks after they have been deployed.

As a developer I find the idea of manually checking someone else's stuff tedious, error prone, and boring as fuck. I'm hoping there is perhaps some tool or browser extension or something, that I can use to maybe select an element and apply some sort of rule to it that can be pass/failed.

Is there anything like this available? Any help would do a lot for my sanity!
