Disadvantages of Visual Testing

  1. It can not detect smaller defects.
  2. It requires the minimum skills to implement. It is a little difficult for beginners.
  3. Sometimes, video recording is not so clear.
  4. Possibilities of containing the detect even though testing has been implemented.
  5. Tests only the visible or light surface.

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.

Features of Visual Testing

Testing of User Interface (UI) Elements: Visual testing confirms that all user interface (UI) components, including text fields, buttons, icons, images and other graphical elements, are presented accurately and positioned in accordance with the design. Arrangement and Coherence of Design: It guarantees that the layout of the programme remains the same on various screens, sizes, and resolutions. To keep a design solid, elements must be positioned and aligned correctly. Verification of Theme and Color: Visual testing verifies that the application’s color scheme and theme comply to the design guidelines. Testing Text and Fonts: Verifying that fonts are presented correctly, that the content is readable and that there are no problems with font size, style, or formatting are all included in this aspect....

Visual Inspection System

Automated Visual Inspection or Visual Inspection is the process of analyzing the products for the entire control of the product quality. Here, the software is developed with an image capturing algorithm and it captures the images for checking the quality of the product which matches with our requirements as is mentioned by the client or business team. It reduces the manual working and provides the best outcome regarding the result. The rate of checking the product is speed and efficient. It ensures the correctness of the product....

Working of Visual Testing

Visual tests generate, compare and analyze browser snapshots to detect if any pixels have changed. These pixel’s differences are called visual pixels....

Visual testing is done because visual errors happen more frequently than one might realize. Some of the reasons for doing visual testing are-...

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....

Tools for automated visual testing

The following are some of the tools for automated visual testing:...

Configuration – Based automated visual testing (Open Source Tools):

CSS visual test: It checks the correctness of the CSS properties with the image generated. VIFF: It finds visual differences between web pages in different environments such as developing, staging, production and browsers. GreenOnion: It checks only the UI part of the website and ensures that the designs, views, etc., are made correctly. Galen Framework: It is used to test the layout of the web application from various devices.  CSSCritic: It is to check the current layout of the web page constantly against the reference image generated early. Baskstop JS: It checks the entire layout or part of the layout of the UI and compares it with DOM screenshots....

Additional types of Visual Testing

Visual Regression Testing: It identifies unintentional visual changes by comparing the application’s current user interface (UI) to a baseline or reference image. Cross-Browser Visual Testing: It guarantees that the application will seem the same in all web browsers, including those with various versions. Responsive Design Testing: It confirms that the user interface (UI) of the programme adjusts to different screen sizes and resolutions. Visual Accessibility Testing: It analyses, if the application’s visual components follow to accessibility guidelines and are usable by people with disabilities. Localization and Internationalization Testing: It confirms that the application’s visual components appropriately adjust to various languages, locales and cultural preferences....

Advantages of Visual Testing

Increased quality of code and UI. Rapid bug detection. Control of Views on different devices and browsers. Easy to implement. Fast implementation. Automation. Reduction of Code. Efficient feedback of results during testing....

Conclusion

Visual testing concentrates on an application’s user interface and visual components, is an essential component of the software testing process. This testing technique is crucial to preserving the overall quality of the software, discovering discrepancies in the design, and guaranteeing a satisfactory user experience. It is not only a best practice but also a deliberate approach to provide software that satisfies functional and aesthetic criteria, increasing user satisfaction and fostering a positive brand perception. Visual testing should be incorporated into the development lifecycle....
