Your Ultimate Guide To Automated Visual Testing
Visual testing compares the visible output of an app or website against a baseline image, automatically. It helps prevent visual discrepancies that go to production because functional testing often misses them. This blog post will explain why you should run visual tests.
What is Visual Testing?
Visual testing is a software testing method that determines the behavior and visual functionality of an application's user interface (UI) or graphical user interface (GUI). Also known as snapshot testing, visual testing in its most basic form compares differences in an image by looking at pixel variations.
Why We Need Visual Testing?
When it comes to visual testing, appearance and behavior of the UI is king. Visual issues like pixel to pixel comparison, rendering, alignment, layout, font change, and overlap are all things that functional testing cannot identify.
Think of the two types of testing as the what (visual) and the how (functional).
Functional testing is designed to see if the software is working as needed. This method focuses on verifying the app is working based on specific functional requirements and meets business needs. Functional testing validates the software's capabilities, features and communication with various components.
Visual testing should be integrated into your existing test scripts and thus your existing CI/CD process. Visual testing helps ensure the UI of your app is working as intended for your users. Several benefits of visual testing include:
