It&#x27;s not actually that terrible, but then again it depends on what you&#x27;re building I suppose.<p>Where I work, I made a fairly robust image diffing utility that runs using Selenium&#x2F;WebDriver on all browsers that we support.  Combined with a robust test suite of many different scenarios, we can make changes to our stylesheets with a pretty high amount of confidence that if anything changed, it&#x27;ll fail the build.
