Visual testing is a crucial component of software development that ensures an application’s user interface and functionality are free of bugs and glitches. Applitools is a powerful testing tool that automates visual testing and helps teams identify visual defects before they can cause issues for users. This article will provide an overview of Applitools and its key features and benefits.

What is Applitools?

Applitools is a visual testing and monitoring platform designed to help development and testing teams ensure that their applications appear and function correctly across different devices, browsers, and screen resolutions. It uses advanced AI-powered image processing technology to automatically compare screenshots of an application's UI with a set of baseline images that represent the expected appearance.

The main features of Applitools include:
  1. Visual AI: Applitools' Visual AI engine, called Eyes, automatically detects visual differences between the baseline and the current version of an application. It highlights these differences and allows you to review them, making it easier to identify and fix visual bugs.
  2. Cross-browser and cross-device testing: Applitools enables you to test your application across multiple browsers, devices, and screen resolutions, ensuring that your application looks and functions correctly for a wide range of users.
  3. Integration with existing testing frameworks: Applitools can be easily integrated with popular testing frameworks like Selenium, Cypress, Appium, and many others. This integration allows you to perform visual validation as part of your existing testing process, ensuring comprehensive coverage of your application.
  4. Dashboard and collaboration tools: Applitools provides a user-friendly dashboard that allows you to review visual differences, manage baselines, and track test results over time. It also includes collaboration tools, enabling teams to work together effectively.
  5. Automated maintenance: Applitools helps reduce the maintenance overhead associated with visual testing by automatically updating baselines when changes are approved and providing smart tools to manage multiple baselines.

How does Applitools work?

Applitools is designed to provide automated visual testing by taking screenshots of the application and analyzing them for changes. It uses advanced algorithms to detect visual differences and anomalies, even when the changes are subtle or complex. In addition, Applitools offers integrations with various testing frameworks such as Selenium, Cypress, Robot Framework, Playwright, WebDriverIO, and Appium, making it easy for teams to integrate visual testing into their existing workflows.

Applitools for web testing

Applitools is a powerful visual testing tool that streamlines quality assurance for web-based applications. It enables teams to identify visual and functional defects on a range of browsers and devices in just minutes, making it an ideal solution for testing at scale. By leveraging Visual AI, Applitools offers a comprehensive way to test web experiences that accurately reflects what users see. It integrates seamlessly with popular testing frameworks such as Selenium and Cypress and low-code tools like and Selenium IDE, allowing teams to add visual tests to their regression testing quickly. With Applitools, teams can test different layers of their web experience, including individual components with Storybook testing, and can set the match level to test every single element or just layouts. In addition, the Applitools Ultrafast Grid leverages AI to re-render each viewport, running visual tests on hundreds of different browsers, screen sizes, and orientations in just minutes.

Overall, Applitools enables teams to automate quality assurance and efficiently detect visual and functional bugs across various devices and browsers. In addition, it offers faster feedback loops, better collaboration across teams, and more efficient testing cycles.

Applitools for mobile testing

Applitools simplifies the testing of native mobile applications for mobile development teams by providing a testing platform powered by Visual AI. This platform enables teams to conduct visual regression testing and ensure bug-free user experiences. The visual locators and stable infrastructure provided by Applitools help to boost test reliability, which is often a challenge for mobile testing. In addition, the platform offers comprehensive device coverage, allowing tests to be run on various Android and iOS devices, viewports, and screen sizes, ensuring visual perfection for every customer. By using Visual AI, teams can write less test code and spend less time on execution while still catching more UI/UX bugs. Applitools Ultrafast Infrastructure enables cross-browser or cross-device tests to run in parallel, reducing cross-platform testing time by up to 90% and improving coverage. With over 50 powerful integrations with testing frameworks and tools, Applitools Eyes makes it easy to add Visual AI to existing projects by writing just one line of code added to a Selenium, Cypress, or other test scripts.

Codeless testing with Applitools

Applitools offers a codeless testing option that allows users to create automated tests without the need to write any code. This is accomplished through a recorder that captures user actions and makes them available for playback. With codeless testing, users can save time and effort. Furthermore, Applitools provides helpful features like element repositories and reusable test steps to make maintenance easier. Finally, Applitools integrates with visual testing solutions to ensure reliable and accurate testing results. However, whether to use codeless or coded testing ultimately depends on the user's preference and what is best suited for their needs.

Applitools advantages

Applitools is a powerful visual testing tool with several advantages over traditional testing methods. Some of the key advantages of Applitools include:
  • AI-powered visual testing: Applitools uses advanced artificial intelligence and machine learning algorithms to detect visual differences and anomalies, even in complex and dynamic web and mobile applications. This allows more accurate and efficient visual testing to identify even the most subtle defects.
  • Cross-browser and cross-device testing: Applitools allows for easy testing of applications across multiple browsers, devices, and resolutions. This saves time and effort and ensures that applications work correctly for all users.
