海外TECH	DEV Community	4 Ways to Automate Visual Regression Tests	https://dev.to/willkre/4-ways-to-automate-visual-regression-tests-39f5	Ways to Automate Visual Regression TestsBefore we get going let s go over some quick questions What does visual regression testing mean Visual regression testing is a process of comparing the visual appearance of an application s UI between two different versions to ensure that there are no unintended visual changes The process involves taking screenshots of various UI elements and comparing them to previously captured screenshots to identify any changes in the visual appearance Visual regression testing helps to ensure that the application s UI remains consistent and visually appealing across different devices browsers and operating systems Why should you automate it Automating visual regression testing can help to identify UI issues early in the development cycle which can save significant amounts of time and money that might otherwise be spent fixing issues later on Think about the time and therefore money that is spent fixing UI quirks that are caught in Q A UAT or production Why wouldn t you automate catching those visual bugs What about manual visual checks Although you can perform manual visual checks it s not recommended to solely rely on them because it takes significantly more time compared to using an automated suite Spotting differences in the UI can be challenging even for subtle visual bugs See the example below can you spot the differences Probably But it d take you a lot longer than an automation suite What percentage of visual bugs are caught by automated visual regression tests Studies from various sources BrowserStack AppliTools etc show that automated visual regression testing can catch most visual bugs with a success rate ranging from to depending on the application s complexity and the testing process used In this article we will explore popular libraries for automating visual regression testing Chromatic Percy Jest Image Snapshot BackstopJS ChromaticChromatic is a visual regression testing tool that is designed specifically for Storybook Chromatic provides a cloud platform which allows users to test and manage the UI components of a project ensuring that any changes made do not result in unexpected visual changes Who uses Chromatic Adobe Auth CircleCI GOV UK BBC etc Pros of ChromaticEasy Integration Having been built specifically for Storybook by the maintainers of Storybook it s seamless to set up for your component library or design system Team Collaboration Chromatic provides a platform for team collaboration by allowing you to share test results with your team members leave comments and discuss any issues Build Analysis Chromatic provides detailed build analysis showing you what changes were made who made them and how they affected your UI components Cons of ChromaticLimited customization options While Chromatic s UI is designed to be easy to use it may not offer as much flexibility or customization as other visual regression testing tools Pricing Chromatic offers a free plan with unlimited collaborators and storybooks However its free tier has a limit of snapshots per month so it s worth considering if the first tier mo is affordable to your team if you think you ll hit that limit Further pricing information can be found here No local testing option Chromatic does not currently offer a way to test visual changes on a local machine before deploying them to the server which could be a limitation for some teams PercyPercy is an all in one visual review platform that offers a wide range of features and integrations It was acquired by BrowserStack which is an industry leader in application and browser testing Percy helps developers catch visual regressions streamline the review process and allows teams to easily collaborate and track changes Who uses Percy Google Sentry Shopify Fastly Basecamp etc Pros of PercyVersatile amp Flexible Percy can be used for visual regression testing in a wide range of applications beyond just Storybook Percy has advanced features such as cross browser testing integrations with popular testing frameworks and a powerful API that allows for more extensive customization and control over your testing processes Scalability Percy scales very well making it easy to manage visual regression tests for even the largest projects Collaboration Percy provides a wide range of collaboration tools including commenting and sharing features that allow developers to work together to identify and resolve issues quickly Cons of PercyLimited customization Some users may find that Percy s out of the box settings and features do not meet their specific testing needs as there are limited options for customization Dependency on external service Since Percy is a cloud based tool developers will need to rely on external service providers for hosting and maintaining the platform which can introduce additional dependencies and potential points of failure Pricing Percy offers a free plan with unlimited collaborators and storybooks However its free tier has a limit of snapshots per month so it s worth considering if the first tier is affordable to your team if you think you ll hit that limit Further pricing information can be found here Which Cloud solution to choose for Storybook In my opinion I would go with Percy if I were already using planning to use it for other visual regression tests e g in Cypress EE test suites so that your visual regression tests are consolidated in a single platform On the other hand if I only needed to perform visual regression tests for Storybook I would opt for Chromatic Chromatic is specifically designed for Storybook by its maintainers making it more compatible and future proof Since Chromatic is optimized solely for Storybook it integrates better with the platform and provides a more streamlined workflow The NPM trends of percy storybook vs chromatic seem to indicate that most people have come to the same conclusion Jest Image SnapshotJest Image Snapshot is a visual regression testing tool built for Jest It allows developers to take snapshots of the rendered components or elements and compare them with the previously stored images to check for any visual differences or changes It works by rendering the component or element and generating an image of the rendered output using a headless browser The generated image is then compared with the previously stored image using pixel to pixel comparison and if any differences are found Jest will report a failed test Who uses Jest Image Snapshot American Express etc Pros of Jest Image SnapshotEasy to Use Jest Image Snapshot is easy to set up and use making it accessible for developers of all levels of experience It integrates seamlessly with Jest a popular testing framework and requires no additional configuration Independent Jest Image Snapshot can be used locally without the need for an external service making it a more convenient and cost effective solution for developers who prefer to test and debug their applications locally Pricing It s an open source project and it s free Cons of Jest Image SnapshotPerformance overhead Local visual regression testing can be resource intensive and running tests can slow down the development process particularly for large scale projects Dependence on Jest As the name suggests Jest Image Snapshot is tightly integrated with the Jest testing framework which may not be suitable for teams using other testing frameworks Limited configuration options While Jest Image Snapshot is easy to set up and use it does not offer as many configuration options as other visual regression testing tools This can be limiting for teams that require more flexibility in their testing BackstopJSBackstopJS is an open source visual regression testing tool for web applications that automates the process of comparing screenshots of the current state of a web application with its previous version to identify any visual changes It uses headless browser automation to simulate user interactions and captures screenshots of web pages BackstopJS can be configured to test multiple pages and responsive design across multiple viewports It also supports user authentication and can be integrated with various CI CD pipelines BackstopJS uses a configuration file to define the URLs to be tested viewports and other settings Pros of BackstopJSFlexible configuration BackstopJS is highly configurable which makes it suitable for testing different types of applications with various visual requirements It allows you to define custom scenarios set up different environments and adjust parameters to achieve the desired level of testing Powerful comparisons BackstopJS provides a powerful image comparison engine that detects even the smallest visual differences It uses pixel by pixel comparison and threshold values to determine whether a change is significant enough to be considered a failure Pricing It s an open source project and it s free Cons of BackstopJSComplexity BackstopJS requires more configuration and setup compared to other visual regression tools which may make it more complex to implement Slower testing BackstopJS can be slower to run compared to other visual regression tools due to how it generates and compares screenshots Limited support While BackstopJS has documentation and community support available it may not be as robust as other tools with larger user bases and more established support networks e g Percy In conclusion each tool offers unique features and benefits as well as potential drawbacks The choice of which to use for visual regression testing depends on various factors such as project requirements team preferences and available resources There are trade offs in selecting each tool and the decision depends on what factors are most important for your project In my opinion Percy offers the most comprehensive and user friendly solution making it an excellent option for teams looking for an advanced tool Chromatic is a suitable option for teams only needing to test their Storybook library while BackstopJS is better suited for teams looking for more comprehensive testing capabilities Jest Image Snapshot is a good option for developers working on smaller projects which use Jest Ultimately incorporating automated visual regression testing into your development process is critical to catching UI defects early and ensuring a high quality user
