What is Visual Testing?

Visual testing is a sort of software testing that focuses on checking the visual features of a user interface. It entails inspecting the appearance and feel of a software application to ensure that it satisfies the design criteria and specifications.

Visual testing can be done manually or automatically by comparing screenshots or photos of the application to the desired design. This form of testing can aid in detecting issues such as inconsistent styling, layout issues, broken images or icons, and other visual flaws that may influence the user experience.

Visual regression tests can be performed manually and automatically. If we talk about automation, automated visual testing typically involves the use of specialized software tools that can capture and compare screenshots or images of an application's user interface. Here's how automated visual testing typically works:

• Test script creation: The tester writes a test script that describes the expected behavior and appearance of the application. This can include defining the locations and properties of UI elements like buttons, menus, and text fields.
• Test Execution: The automated testing tool executes the test script, interacting with the application to capture screenshots or images of the user interface.
• Image comparison: The tool compares the captured images to the expected design, highlighting any visual differences or flaws. These distinctions can be highlighted in a report for scrutiny.
• Analysis and reporting: The tester examines the automated test results and looks for discrepancies. They can then investigate the source of the problems and determine whether any changes to the application are required.
