10-10: Good addition of test ID for testability.Adding the
data-testid="spinner"attribute improves component testability by providing a reliable selector for the spinner element in tests. This pattern follows best practices for component testing.packages/ui-components/src/__tests__/ButtonLoading.test.ts (1)
1-27: Well-structured test suite with good coverage.The test suite comprehensively covers the key functionality of the ButtonLoading component:
- Presence of spinner when loading
- Button disabled state during loading
- Absence of spinner when not loading
The tests are clear, concise, and follow testing best practices by using appropriate Testing Library methods.

🧹 Nitpick (assertive)
Consider adding a disabled state test for completeness.
While you have good coverage of the loading functionality, consider adding a test that verifies the button remains enabled when loading is false and disabled is false, and disabled when disabled is true regardless of loading state.
+ it('should respect disabled prop when loading is false', () => {
+ render(ButtonLoading, {
+ loading: false,
+ disabled: true
+ });
+ const button = screen.getByRole('button');
+ expect(button).toBeDisabled();
+ });
+
+ it('should be enabled when loading and disabled are false', () => {
+ render(ButtonLoading, {
+ loading: false,
+ disabled: false
+ });
+ const button = screen.getByRole('button');
+ expect(button).not.toBeDisabled();

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

@hardingjam I see the confusion. You're right that there's a test checking that the button is disabled when loading is true. However, looking at your component code:
<Button disabled={loading || disabled} {...$$props} on:click>The button can be disabled in two ways: when loading is true OR when disabled is true. The current tests only verify the first condition (when loading is true), but don't test the behavior when the disabled prop is independently set to true while loading is false.
The tests I suggested would specifically verify these additional conditions for complete coverage of the component's behavior. But if you feel the current test coverage is sufficient for your needs, that's perfectly fine!

🧹 Nitpick (assertive)
Consider testing slot content.
The component accepts slot content, but there's no test to verify it renders correctly. Consider adding a test that verifies the button text is rendered properly.
+ it('should render slot content', () => {
+ render(ButtonLoading, {
+ loading: false,
+ $$slots: {
+ default: '<span>Button Text</span>'
+ }
+ });
+ expect(screen.getByText('Button Text')).toBeInTheDocument();
