Introduction to Visual Testing
The following article provides an outline for Visual Testing Tools. Visual tests ensure that no previously successful changes to the software break anything. The visual regressional test ensures that problems of any style do not appear when software changes are made. The request should remain as good as it was. A screenshot of the current UI is captured and compared with an original screenshot in the visual regression testing tool. The visual regression tests, therefore, look at the differences in history. It confirms that, even after code modifications, the web page still provides the expectations across various browsers.
List of Visual Testing Tools
Given below is the list of Visual Testing Tools:
The tool has gained massive support and an active community on the market for over a decade. It allows simultaneous testing on various browsers on various machines and reduces the time required to test valuable and significant projects.

This tool is very easy to configure and set up when you work on automated unit testing for your developer. Jest provides features such as an interactive watch mode to improve workflows. In addition, it is clever enough to test the changes made to your code repository since your last commit. The failing test may also be executed first in the preceding run, which enables changes needed to fix the tests.
A storybook is an easy-to-use tool for constructing a library of visual components, allowing you to browse a library of components, view the various states of each component, and develop and test components. In addition, it allows you to visually regress all components using the visual validation test tools provided.
Similar to Gemini, Selenium is dependent on WebdriverCSS for its features. As part of the WebdriverIO ecosystem, it enhances the main framework and offers an improved experience. Integrating with other applications such as Jasmine, Mocha, and Cucumber is also possible. Js
GreenOnion helps solve regression bug problems and the tests between developers and devs of the problem of HTML and CSS problems. It also helps you to track the presentation layer BDD and TDD. Finally, GreenOnion helps you obtain the same front-end test results you enjoyed up-to-date in your unit and integration tests.
The developer of BBC News developed the original Wraith to compare screenshot websites using a headless browser. For screenshots of different environments, the Wraith Selenium uses SlimerJS or PhantomJS and produces the differences between the two images highlighted in blue.
BackstopJS automates your reactive web-based visual regression testing over time by comparing DOM screenshots. A good starting point for BackstopJs would be an article on automating the CSS regression tests by css-tricks.
11. Selenium Visual Diff
Selenium Visual Diff aims to integrate better screenshots that take functional tests, storage, and versioning of scrubbers performed in maven selenium2 so that visual differences between the two application versions are reported.
It seems sufficient as a list to give you an idea about tools that your development team might want to know. Then, you can choose any of them based on your requirements.
