Testing Blazor Applications with Playwright
When to Use This Skill
Use this skill when:
- Writing end-to-end UI tests for Blazor Server or WebAssembly applications
- Testing interactive components, forms, and user workflows
- Verifying authentication and authorization flows
- Testing SignalR-based real-time updates in Blazor Server
- Capturing screenshots for visual regression testing
- Testing responsive designs and mobile emulation
- Debugging UI issues with browser developer tools
Core Principles
- Wait for Rendering - Blazor renders asynchronously; use proper wait strategies
- Test Attributes - Use
data-testordata-testidattributes for stable selectors - Headless by Default - Run tests headless in CI, headed for local debugging
- Handle Error UI - Always check for
#blazor-error-uito catch unhandled exceptions
