Description

Develop comprehensive test suite for the contact form component to ensure reliable message submission, proper validation, and optimal user experience. This customer-facing component requires thorough testing of all user interactions and edge cases.

Test Cases

Rendering

• ✅ Renders correctly with all form fields
• ✅ Renders with proper labels and placeholders
• ✅ Submit button displays correct text

Validation

• ✅ All fields required (name, email, subject, message)
• ✅ Email validation (valid/invalid formats)
• ✅ Message length validation (minimum and maximum)
• ✅ Name field validation (minimum length, special characters)
• ✅ Subject field validation

Form Submission

• ✅ Successful submission workflow
• ✅ Success message displayed after submission
• ✅ Form reset after successful submission
• ✅ Submit button disabled during submission

Error Handling

• ✅ Error handling for API failures
• ✅ Network error messages displayed
• ✅ Validation error messages displayed
• ✅ Server error handling (500, 400 responses)

UI States

• ✅ Loading state displays during submission
• ✅ Disabled state on submit button while loading
• ✅ Form fields disabled during submission
• ✅ Error state styling applied correctly

Acceptance Criteria

• 80% component coverage minimum
• All user interactions tested (typing, clicking, submitting)
• API endpoint properly mocked
• No console errors or warnings during tests
• Form validation matches production behavior
• All error states properly handled and displayed
• Success flow validated end-to-end
• Tests run in <3 seconds

Technical Notes

• Use React Testing Library for component testing
• Mock API calls with msw (Mock Service Worker) or jest.mock
• Use userEvent for realistic user interactions
• Test with @testing-library/jest-dom matchers
• Verify form data structure matches API contract
• Test both synchronous and asynchronous validation

Testing Strategy

1. Rendering tests: Verify all elements present
2. Validation tests: Test field-level and form-level validation
3. Interaction tests: Test user input and form submission
4. Error scenarios: Test all failure modes
5. Accessibility: Verify ARIA labels and keyboard navigation

Edge Cases to Cover

• Empty form submission attempts
• Partial form completion
• Special characters in input fields
• Very long message content
• Rapid successive submissions
• Network timeout scenarios
• Form submission after validation errors

Accessibility Considerations

• Keyboard navigation works correctly
• Error messages announced to screen readers
• Focus management on error and success states
• ARIA labels present on all form controls
