111-149: Excellent edge case coverage with room for optimization.The edge case tests are comprehensive, covering important scenarios like boundary values, negative numbers, values above 100, and decimal inputs. This ensures robust handling of various input types.
Consider refactoring to eliminate duplicate component renders within individual tests:
it('handles score of 0', () => { - render(<MetricsScoreCircle score={0} />) + const { container } = render(<MetricsScoreCircle score={0} />) expect(screen.getByText('0')).toBeInTheDocument() // Should be red styling - const { container } = render(<MetricsScoreCircle score={0} />) expect(container.querySelector('[class*="bg-red"]')).toBeInTheDocument() })Similar optimization can be applied to the other edge case tests that currently render twice.
151-163: Basic accessibility testing with potential for enhancement.The current accessibility tests provide good coverage of text content accessibility and tooltip presence. Consider expanding accessibility testing to include ARIA attributes, keyboard navigation, and screen reader compatibility for more comprehensive accessibility validation.
207-209: Remove trailing empty lines.Clean up the trailing empty lines at the end of the file for better code hygiene.

1-12: Excellent test setup and mocking strategy.The imports are appropriate and the mock implementation for the Tooltip component is well-designed. It preserves the original interface while exposing testable attributes through data attributes, enabling proper isolation of the component under test.
14-34: Well-structured basic rendering tests.These tests effectively verify the core rendering functionality, ensuring the component displays the score value and static labels correctly. The tests are focused and use appropriate assertions.
36-72: Comprehensive styling tests with excellent boundary value coverage.The tests effectively verify color schemes for different score ranges and include critical boundary value testing. The boundary tests for scores 50, 74, and 75 are particularly valuable for ensuring correct conditional logic.
Consider that the CSS class pattern matching approach (
[class*="bg-green"]) assumes specific naming conventions and could be brittle if styling implementation changes, but this is acceptable for the current testing needs.
74-85: Effective animation testing with proper boundary validation.The tests correctly verify both the presence and absence of pulse animation based on the score threshold of 30. The boundary testing ensures the conditional logic works precisely at the cutoff point.
87-93: Solid tooltip functionality testing.The test effectively utilizes the mocked Tooltip component to verify both content and placement attributes, ensuring the tooltip integration works as expected.
95-109: Good DOM structure validation.These tests provide valuable verification of the component's HTML structure and CSS classes, ensuring the layout elements are properly rendered. The combination of screen and container queries is appropriate for testing different aspects of the DOM.
165-172: Appropriate hover effects testing.The test effectively verifies that hover-related CSS classes are applied to the component, ensuring interactive behavior is present. The CSS class pattern approach is suitable for this level of testing.
174-206: Excellent integration testing approach.These integration tests are particularly valuable as they verify that all component features (styling, animation, score display, tooltip) work together correctly for different score scenarios. This holistic testing approach ensures the component functions properly as a complete unit.
