Setup Visual Testing

Setup visual regression testing

Instructions

1. **Visual Testing Strategy Analysis**

• Analyze current UI/component structure and testing needs
• Identify critical user interfaces and visual components
• Determine testing scope (components, pages, user flows)
• Assess existing testing infrastructure and integration points
• Plan visual testing coverage and baseline creation strategy

2. **Visual Testing Tool Selection**

• Evaluate visual testing tools based on project requirements:
• **Chromatic**: For Storybook integration and component testing
• **Percy**: For comprehensive visual testing and CI integration
• **Playwright**: For browser-based visual testing with built-in capabilities
• **BackstopJS**: For lightweight visual regression testing
• **Applitools**: For AI-powered visual testing and cross-browser support
• Consider factors: budget, team size, CI/CD integration, browser support

3. **Visual Testing Framework Installation**

• Install chosen visual testing tool and dependencies
• Configure testing framework integration (Jest, Playwright, Cypress)
• Set up browser automation and screenshot capabilities
• Configure testing environment and viewport settings
• Set up test runner and execution environment

4. **Baseline Creation and Management**

• Create initial visual baselines for all critical UI components
• Establish baseline approval workflow and review process
• Set up baseline version control and storage
• Configure baseline updates and maintenance procedures
• Implement baseline branching strategy for feature development

5. **Test Configuration and Setup**

• Configure visual testing parameters (viewports, browsers, devices)
• Set up visual diff thresholds and sensitivity settings
• Configure screenshot capture settings and optimization
• Set up test data and state management for consistent testing
• Configure async loading and timing handling

6. **Component and Page Testing**

• Create visual tests for individual UI components
• Set up page-level visual testing for critical user flows
• Configure responsive design testing across different viewports
• Implement cross-browser visual testing
• Set up accessibility and color contrast visual validation

7. **CI/CD Pipeline Integration**

• Configure automated visual testing in CI/CD pipeline
• Set up visual test execution on pull requests
• Configure test result reporting and notifications
• Set up deployment blocking for failed visual tests
• Implement parallel test execution for performance

8. **Review and Approval Workflow**

• Set up visual diff review and approval process
• Configure team notifications for visual changes
• Establish approval authority and review guidelines
• Set up automated approval for minor acceptable changes
• Configure change documentation and tracking

9. **Monitoring and Maintenance**

• Set up visual test performance monitoring
• Configure test flakiness detection and resolution
• Implement baseline cleanup and maintenance procedures
• Set up visual testing metrics and reporting
• Configure alerting for test failures and issues

10. **Documentation and Team Training**

• Create comprehensive visual testing documentation
• Document baseline creation and update procedures
• Create troubleshooting guide for common visual testing issues
• Train team on visual testing workflows and best practices
• Set up visual testing standards and conventions
• Document visual testing maintenance and optimization procedures
