SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the process of testing Blazor components by providing a robust framework for simulating component behavior and verifying their output without needing a full browser.

Core Features & Use Cases

  • Component Rendering: Test how Blazor components render with different parameters and child content.
  • Event Handling: Simulate user interactions like clicks and form submissions to verify event callbacks.
  • JS Interop Mocking: Mock JavaScript calls made by Blazor components for isolated testing.
  • Use Case: You've built a Blazor component for displaying a user profile. Use this Skill to ensure it renders the correct user information, handles profile edits via events, and correctly mocks any JavaScript calls for UI enhancements.

Quick Start

Use the dotnet-blazor-testing skill to test the rendering of a Blazor component named 'UserProfile' with a specific user ID.

FAQPage Schema
How do I test Blazor components without launching a full browser?

Test Blazor components without a browser by using bUnit to render components in memory and verify their output. This framework simulates component behavior for isolated testing without requiring browser automation overhead.

Can I mock JavaScript interop calls when testing Blazor WebAssembly components?

Yes, mock JavaScript interop calls when testing Blazor WebAssembly components using bUnit. The framework provides JS interop mocking capabilities to isolate component logic from JavaScript dependencies during test execution.

How do I simulate user clicks and form submissions in Blazor component tests?

Simulate user clicks and form submissions in Blazor component tests by using bUnit's event handling features. You can trigger event callbacks to verify that your Blazor components respond correctly to user interactions.

What testing frameworks do I need to test Blazor components with bUnit?

Testing Blazor components with bUnit requires xUnit as the test runner alongside the bUnit library. These frameworks work together to provide isolated component verification for both Blazor Server and WebAssembly applications.

Does bUnit support testing cascading parameters in Blazor components?

Yes, bUnit supports testing cascading parameters in Blazor components. You can verify component rendering and behavior when cascading values are passed down through the component hierarchy during isolated tests.
