What is Visual Testing?
Visual testing is a testing activity that aims to verify the presentation properties of a GUI object under various conditions. Testing of GUI based systems and software consists of the validation of both the GUI visual layout and its functionality.
Visual testing provides developers with the ability to monitor what was happening at the point of software failure by presenting the data in such a way that the developer can efficiently ﬁnd this information.
For example, checking that a given object has the correct font size can be handled in isolation, while verifying that two objects are appropriately aligned will require comparing the position properties of both of them.
Why everyone should use Visual Verification in Software Testing
The concept of visual testing is showing someone a problem or test failure, rather than just describing it, which increases clarity and understanding. Testers can show the problem and the events leading up to it to developers rather than just describing it and (in many cases) there will be no need to replicate test failures. The developer can focus on the cause of the fault and how it should be fixed.
Visual testing is especially desirable for environments that utilize agile methods in their development of software as agile software testing methods require elevated communication between testers and developers and collaboration within teams.
