Visual Testing refers to testing the visual aspects of an application.

Visual bugs can be an unpleasant experience to users even though your app is functionally stable. So, it is important to ensure they do not slip through.

Would functional testing not suffice, you ask?

While it’s possible to test for visual elements using traditional functional tests, oftentimes, they are difficult to maintain considering it involves more locators and test code. Almost like using a sledgehammer to crack a nut! 🥜

Now that we have some context, here are some helpful recommendations.
