Fixes TypeError: Cannot read properties of undefined (reading 'name') occurring in DeviceInfo component when device prop is undefined. Changes: - DeviceInfo: Add null checks and graceful error handling for undefined device prop - DeviceInfo: Enhanced formatValue to return 'N/A' for null/undefined values - SystemStatsPanel: Add guard clauses for empty devices array - SystemStatsPanel: Display helpful message when no devices available - Added monitoring to log when devices array is missing for debugging - Added i18n keys for error messages Root cause: Component attempted to access properties on undefined device object when SystemStats API returned empty devices array or malformed data. Solution: Defensive programming with null checks and user-friendly error messages. Tests updated to verify graceful handling instead of throwing errors.

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.
