UI Testing / Visual Testing
Definition, Types, and Advantages

UI Testing and Visual Testing are critical components of market research. Integrating crowd participants for testing is an emerging trend that offers researchers a diverse set of perspectives and real-world testing conditions to ensure that the UI is user-friendly and functions correctly.

UI Testing or Visual Testing refers to the process of assessing the user interface (UI) and its functionality to ensure it is consistent, error-free, and meets the expectations of the end-users.

What is UI Testing / Visual Testing?

UI testing or user interface testing, also known as visual testing, is done to check how smoothly the interface of a website/application works. In short, it is done to improve the user experience of a given application, software, or website. It pertains to validating the user interface with fewer sites or application abandonment. Users tend to leave a website or uninstall an application when they experience poor interface or navigation or find the visuals unacceptable.

Visual testing aims to ensure the visual elements of the application or website, like colors, fonts, images, layouts, header, and footer, are how they should be. It also ensures the website is responsive on all screen sizes and browsers. Furthermore, the application should be accessible on all devices and operating systems. These are a few aspects visual testing considers.

How is UI Testing / Visual Testing done?

UI / Visual testing is performed by a Quality Analyst (QA) or other human testers. Tests are run on various browsers, and snapshots are taken to compare, generate and analyze the pixel differences. The QA first runs the developer’s code to check the user interface of the site or application. They also use a browser automation tool replicating the actions – as if a user is accessing a website/application. Such actions include typing text into a field, navigating the website menu, scrolling down to the website footer, etc.

  • After a developer’s code is run, snapshots are taken that act as a prototype to which all other changes are compared.
  • A QA runs a developer’s code again in the background. This time any change that is identified will automatically be captured.
  • Each captured screenshot is compared to the baseline image for that particular code and software.
  • If any difference is identified between the images, the test is considered failed.
  • After the test run is complete, the report is generated. This report specifies all the differences between the prototype and final images.
  • A developer’s job is to identify the differences caused due to incorrect codes or bugs. Once the developer fixes them, the code is run again.
  • If the differences are fixed, the test no longer fails. The developer now has to update the differences so that visual tests run in the future can be compared to new prototype images.

Benefits of UI / Visual Testing

UI / Visual Testing is a critical component of ensuring that user-facing applications are of high quality and provide a positive user experience. By understanding the benefits of UI / Visual Testing, companies can better appreciate the value of investing in this process and how it can improve the overall quality of their applications.

  • Compliance with Standards and Regulations: UI / Visual Testing can help to ensure compliance with industry standards and regulations by detecting and addressing potential compliance issues early in the development process.

Limitations of UI Testing / Visual Testing

  • Not a holistic approach
    Visual testing does not take into consideration the functional aspect of the website/application. It only looks at the upper layer, i.e., the visual appearance. Everything that goes behind the functionality of any website, like non-GUI-related issues – software-related issues are neglected.
  • Requires human interference
    Even with automated UI/visual testing, human interference is required. The need to run the test and fix the bugs requires human testers and developers. Developers with skills and knowledge to fix the website design and testers to compare the screenshots with baseline screenshots are needed to make visual testing work.
  • Not for all applications/website
    Any website/application that doesn’t have much GUI needs does not require visual testing. For instance, an e-commerce website may benefit most from such testing, while a government website may not benefit a lot from it.
