   - Follow standard ESLint configuration
+  - Use Vitest for testing React components
+  - Use React Testing Library for component testing
+  - Mock FluentUI components in tests due to JSDOM limitations
+  - Maintain 80% code coverage across branches, functions, lines, and statements
+  - Focus on testing user interactions and component behavior
+  - Use semantic queries (getByRole, getByLabelText) over test IDs when possible
 
 - **YAML**:
   - Use consistent indentation (2 spaces)
