* add image outputs on Vue nodes * add unit tests and update cursor pointer * use testing pinia * properly mock i18n in component test * get node via current graph * use subgraph ID from node creation * add better error handling for downloadFile util * refactor: simplify image preview component architecture - Replace awkward composable pattern with standard Vue component state - Fix reactivity issues where images didn't update on new outputs - Add proper subgraph-aware node resolution using NodeLocatorId - Enhance accessibility with keyboard navigation and ARIA labels - Add comprehensive error handling and loading states - Include PrimeVue Skeleton for better loading UX - Remove unused composable and test files The image preview now properly updates when new outputs are generated and follows standard Vue reactivity patterns. * resolve merge conflict with main - Keep both subgraphId field and hasErrors field from main - No conflicts in other files (LGraphNode.vue and main.json merged cleanly) * Fix LGraphNode test by adding proper Pinia testing setup Added createTestingPinia and i18n configuration following the pattern from working ImagePreview tests. Resolves test failures due to missing Pinia store dependencies. All 6 tests now pass successfully.
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
pnpm test:unit
# Run unit tests in watch mode
pnpm test:unit:dev
# Run component tests with browser-native environment
pnpm test:component
Refer to the specific guides for more detailed information on each testing type.
