As development teams eliminate manual testing and focus only on test automation, everyone lives and dies by automated testing. It is repeatable, faster (than manual), and should be preventing bugs, right? How does your automated test coverage compare to manual testing? You have more automated tests for Unit, API, Integration, and Functional UI. But the forgotten test coverage is often Visual testing! Typically, automated testing does not extend checks for visual components of your application.
I have found that teams writing automated Functional UI tests do not understand the difference between these and visual tests. Do you understand the difference? Your functional coverage could be that you’ve identified the main workflows in the app, and visual coverage validates how specific visual components appear in the app. Or it could be more. Without a clear picture of when to use what and why, you could be missing out, or even wasting time. It is important to separate the two levels of tests. Don’t blend the two.
