Why Functional Testing Can’t Cover Visual Testing?
Visual bugs are rendering issues. Rendering validation is not caught by functional testing tools. Functional testing measures functional behavior. But, if there is a requirement to check the functionality of the website, in that case, function testing works properly and ensures the same. If the visualization of the website is very messy as not expected then it will not be detected by functional testing.
Example: While creating a website the submit button is placed at the center but after the entire process by mistake if it is moved to the right side of the browser page then during the functional testing it will not catch or find that defect that the submit button is wrongly placed. Because it checks whether the submit button functionality is working properly or not. Here, it can’t cover the visual testing.
In the case of visual testing implementation, it compares the various snapshots with the baseline snapshots and will detect the defect that the submit button is wrongly placed. It helps the tester to find the defect with minimum test runs.
Visual Testing – Software Testing
Visual Testing is also called Visual UI Testing. It validates whether the developed software user interface (UI) is compatible with the user’s view. It ensures that the developed web design is correctly following the spaces, sizes, shapes, and positions of UI elements. It also ensures that the elements are working properly with various devices and browsers. Visual testing validates how multiple devices, browsers, operating systems, etc., affect the software.
