Visual Regression Testing Automation Workflow
This workflow automates the generation of webpage screenshots and compares them with an AI visual model to achieve visual regression testing for websites. It manages the list of URLs through Google Sheets, uses Apify to generate baseline and latest screenshots, stores them in Google Drive, and intelligently detects visual differences using the Google Gemini model. Ultimately, it automatically summarizes the detection results and generates Linear task reports, significantly enhancing the efficiency of website quality monitoring. This helps development and testing teams quickly identify abnormal changes on webpages, ensuring website stability and user experience.
Workflow Name
Visual Regression Testing Automation Workflow
Key Features and Highlights
This workflow automates visual regression testing of web pages by generating screenshots and comparing them using AI-powered visual models. It intelligently detects changes in webpage content, images, colors, and layout. Leveraging Google Sheets to manage URL lists, Apify services to capture webpage screenshots, Google Drive for image storage, and Google Gemini (PaLM) models for visual analysis, the workflow automatically aggregates detection results and generates Linear task reports. This significantly enhances the efficiency of website quality monitoring.
Core Problems Addressed
Traditional visual regression testing relies on manual screenshot comparisons, which are time-consuming, labor-intensive, and prone to oversight. This workflow automates the generation of baseline screenshots and periodically captures the latest page images. By utilizing advanced AI visual models, it accurately identifies visual differences, enabling development and testing teams to quickly detect abnormal webpage changes, thereby ensuring website stability and an optimal user experience.
Use Cases
- Automatic detection of visual defects after website updates
- Regression testing within Continuous Integration/Continuous Deployment (CI/CD) pipelines
- Regular quality monitoring of multi-page websites
- Collaborative verification of visual consistency between design and development teams
- Any scenario requiring automated monitoring of webpage appearance changes
Main Process Steps
- Retrieve Webpage List: Read webpage URLs and screenshot information from Google Sheets.
- Generate Baseline Screenshots (Part A): Use Apify screenshot service to capture baseline images, upload them to Google Drive, and update image IDs in Google Sheets.
- Scheduled Test Trigger (Part B): Periodically initiate the testing process via a Schedule Trigger.
- Capture Latest Screenshots: Invoke Apify again to obtain the most recent webpage screenshots.
- Download and Merge Screenshots: Download baseline and latest screenshots for comparison preparation.
- Visual Comparison Analysis: Employ Google Gemini Chat model to compare images, intelligently detecting changes in text, images, colors, and positioning.
- Filter and Aggregate Results: Identify webpages with detected changes and consolidate all findings.
- Generate Report: Create a Markdown-formatted report of visual changes and automatically create tasks in Linear for tracking and resolution.
