Awesome Visual Testing with Percy

One type of testing that’s incredibly important but often overlooked is visual testing. Functional testing is incredibly important but the truth is that users expectthings to work but the first thing they’ll notice is things that look broken. Oftentimes your selenium and unit tests will pass despite a hideous visual regression. That’s where a service like Percy comes in — Percy makes visual regression testing easy!
