Best Visual Testing Tools Report

Visual Testing is the important part of Software Test Life Cycle.  Visual Testing performed to ensure that visual elements of Website of Website or Application like layout, images, buttons and functionalities are working as expected. With the Digital Disruption in Software Industries, each Software Development Company deploying code so frequently even on the Daily Basis. In this case, keeping the track record of UI changes is so difficult but fortunately some good Visual Automation Testing Tools make it so easy.

This article presents the comprehensive details of Top 10 Visual Automation Testing Tools Details includes features, drawbacks, pricing and supported platforms.

What is “Visual Testing”?

Did you know what “Visual Testing” means? It refers to the evaluation of an application’s visible output and compares it with the outcomes anticipated by design. In other words, it assists in identifying “visual flaws,” which are separate from strictly functional bugs and which affect the appearance of a page or screen. Applitools, an automated Visual Testing tool, can help to speed up this Visual Testing and reduce errors that may occur during manual verification.

It is also known as “visual UI testing,” which ensures that the software user interface (UI) is working as expected. By analyzing visual testing results  we get detailed idea  about the color, design, theme, and each element of the web page look accurate and give functional results.

 What is Manual Visual Testing?

Companies utilize manual testers to detect visual problems because automated functional testing techniques are inefficient for doing so. Manual Visual Testing entails contrasting two screenshots, one from your app’s most recent version and the other from a known-good baseline image. You need to take your time with each pair of photographs to be sure you’ve caught every problem. particularly if the page is lengthy or contains numerous graphic components.

Can we automate Visual Testing?

There are plenty of Visual Automation Testing tools available in market. These tools work on very simplified steps. In visual Testing, we need to capture screenshot and compare with previous version. This comparison usually happened on image properties like pixel, size and color. This comparison can be done manually or via AI/ML based algorithm. Automated Visual Testing can save resources by detecting and fixing the  visual bugs in early stage of development which can save enormous cost.

What is the Process of Visual Testing?

In order to determine whether any pixels have changed, visual tests create, examine, and contrast browser snapshots. These pixel disparities are known as visual differences (also known as perceptual differences, diffs, CSS differences, and UI differences). It continues with the following steps:

  • an examination of the test runner’s ability to write and run the test.
  • A browser automation framework

As result of Automation execution, we get detailed visual testing report where we can figure out visual issues. The points that highlight the differences between the final and expected images will need to be sought out from this test execution.

 

Importance of Visual Testing
