title: Are there tools for regression/sanity testing a live website?
body: <p>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.</p>
  <p>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.</p>
  <p>Is there anything like this available?  Any help would do a lot for my sanity!</p>
