12-80: Good coverage of torch_input/1 variationsThe tests cover various input types (text, checkbox, select, textarea) and error rendering, providing a solid foundation for testing this component.
A few suggestions for enhancing test coverage:
- Consider adding tests for custom CSS classes and other HTML attributes
- Test handling of nil/empty values
- Verify accessibility attributes (aria-* attributes)
108-125: LGTM: flash_messages test covers the essentialsGood test for verifying multiple flash message types are rendered properly with appropriate classes.
Consider adding tests for edge cases such as:
- Empty flash map
- Flash types other than info/error
152-158: LGTM: translate_errors/2 test is concise and clearThe test properly validates filtering and translating errors for a specific field.
Consider adding a test for handling a field with no errors to ensure it returns an empty list.
1-159: Overall excellent test coverage for Torch.ComponentThis test file provides a strong foundation for unit testing the Torch.Component module. The tests are well-structured, focused, and verify the core functionality of each component and helper function.
While the current tests provide good basic coverage, consider extending them with:
- Additional edge cases (nil values, empty collections)
- Testing more complex scenarios (multiple errors for a field)
- Verifying accessibility features
This implementation aligns well with the PR objective of adding basic unit test coverage for Torch.Component.

1-11: Excellent test module setup!The module is well-structured with appropriate imports, aliases, and ExUnit configuration. Using
async: trueis good for test performance, and importing only the specific functions being tested is a best practice.
82-93: LGTM: torch_label test is concise and effectiveThe test properly validates the basic functionality of the torch_label component, confirming it renders correctly with the expected attributes.
95-106: LGTM: torch_error test is clear and focusedThis test effectively verifies that error messages are rendered with the appropriate CSS class.
127-138: LGTM: torch_flash test is straightforward and effectiveThe test properly validates single flash message rendering.
140-150: LGTM: Good tests for translate_error/1Tests cover both interpolated and simple error message translation.
