- Add preInit hook to ComfyExtension interface that runs before canvas creation - Implement preInit invocation in app.ts after extension loading - Create example extension demonstrating header provider registration - Add comprehensive tests for hook execution order and error handling This enables extensions to register services and cross-cutting concerns before any other initialization occurs.

ComfyUI Frontend Testing Guide
This guide provides an overview of testing approaches used in the ComfyUI Frontend codebase. These guides are meant to document any particularities or nuances of writing tests in this codebase, rather than being a comprehensive guide to testing in general. By reading these guides first, you may save yourself some time when encountering issues.
Testing Documentation
Documentation for unit tests is organized into three guides:
- Component Testing - How to test Vue components
- Unit Testing - How to test utility functions, composables, and other non-component code
- Store Testing - How to test Pinia stores specifically
Testing Structure
The ComfyUI Frontend project uses a mixed approach to unit test organization:
- Component Tests: Located directly alongside their components with a
.spec.tsextension - Unit Tests: Located in the
tests-ui/tests/directory - Store Tests: Located in the
tests-ui/tests/store/directory - Browser Tests: These are located in the
browser_tests/directory. There is a dedicated README in thebrowser_tests/directory, so it will not be covered here.
Test Frameworks and Libraries
Our tests use the following frameworks and libraries:
- Vitest - Test runner and assertion library
- @vue/test-utils - Vue component testing utilities
- Pinia - For store testing
Getting Started
To run the tests locally:
# Run unit tests
npm run test:unit
# Run unit tests in watch mode
npm run test:unit:dev
# Run component tests with browser-native environment
npm run test:component
Refer to the specific guides for more detailed information on each testing type.
