Ensuring the visual integrity of web pages is a crucial aspect of web development. It involves verifying that the layout and design elements appear as intended across various browsers and devices. Automating this process can save a significant amount of time and effort, especially when dealing with multiple projects and web pages. In this article, we explore several tools and methods for automating ‘look and feel’ testing.
Tools for Automated Visual Testing
Several tools have been developed to automate the visual testing of web and mobile applications. These tools primarily differ in their approach to visual comparison, integration capabilities, and whether they are open source or commercial. Below are some notable tools:
- Applitools Eyes: This is a commercial tool that offers a free plan and is considered one of the most advanced for visual testing. It uses a sophisticated comparison engine that mimics human visual perception, eliminating the need to manually set thresholds or mark screen areas. It supports integration with automation frameworks like Selenium and Appium, and offers an extension for code-free testing.
- WebdriverCSS: An open source tool built on WebdriverIO, a Selenium wrapper in JavaScript. It uses GraphicsMagick for image comparison and allows you to set a threshold for image differences. Ideal for those already using WebdriverIO, it simplifies adding visual checkpoints to your tests.
- Sikuli: Another open source tool that focuses on automating interactions based on visual elements on the screen, using its own automation framework.
Considerations for Automated Visual Testing
While automated visual testing tools can significantly reduce manual effort, it’s important to consider the potential brittleness of such tests. Minor changes in UI elements or differences across browsers can lead to frequent updates of failing tests. It’s advisable to complement automated testing with human verification to ensure comprehensive coverage and accuracy.
Why Choose Automated Testing?
Automated testing is not just about reducing manual effort; it also ensures consistency and reliability in test results. By using tools like Applitools Eyes or WebdriverCSS, teams can focus on more critical tasks, while automated scripts handle repetitive visual checks.
Enhancing Automated Testing with Repeato
For those looking to streamline their mobile app testing processes, Repeato offers a compelling solution. As a no-code test automation tool for iOS and Android, Repeato allows users to create, run, and maintain automated tests efficiently. Unlike traditional tools such as Appium, which can be slow and unstable, Repeato leverages computer vision and AI to provide fast and reliable test execution. It’s particularly beneficial for teams aiming to quickly iterate and maintain high-quality apps.
