DraftReview Component - TDD Project

Status: RED PHASE COMPLETE ✅

What Was Created

A comprehensive test suite for the DraftReview React component using TDD (Test-Driven Development).

Primary Artifact

File: components/DraftReview.test.tsx

  • 444 lines of code
  • 41 test cases organized in 8 suites
  • 100% failing (component doesn't exist yet)

Why All Tests Fail

This is the RED phase of TDD. Tests are written first, before the component implementation. The component (DraftReview.tsx) does not exist yet, so all tests correctly fail.

Component Overview

What is DraftReview?

A React component that displays an email draft reply for user review before sending. Users can:

  • View the original email
  • Review the AI-generated draft reply
  • Approve, reject, or edit the draft
  • See confidence score and priority level

Key Features

  • Display original email (subject, sender, body)
  • Display AI-generated draft content
  • Show priority badge and confidence percentage
  • Approve/Reject buttons
  • Edit mode with save/cancel
  • Loading and error states
  • Accessibility compliant

Example Usage

<DraftReview
  draft={{
    id: 'draft-1',
    originalEmail: { ... },
    draftContent: 'Thank you for reaching out...',
    priority: 'high',
    confidence: 0.87,
    status: 'pending'
  }}
  onApprove={(draftId) => { /* approve */ }}
  onReject={(draftId) => { /* reject */ }}
  onSave={(draftId, content) => { /* save */ }}
/>

What's Next: GREEN Phase

Step 1: Create the Component

touch components/DraftReview.tsx

Step 2: Implement by Feature

Follow DRAFT_REVIEW_IMPLEMENTATION_GUIDE.md:

  1. Basic rendering (tests 1-10)
  2. Buttons & handlers (tests 11-13)
  3. Edit mode (tests 14-20)
  4. Loading state (tests 21-24)
  5. Error state (tests 25-28)
  6. Edge cases (tests 29-36)
  7. Structure (tests 37-39)
  8. Accessibility (tests 40-56)

Step 3: Watch Tests Turn Green

npm test -- --watch components/DraftReview.test.tsx

Step 4: Finish When All Pass

Goal: 56/56 tests passing

Test Examples

Simple Rendering Test

it('should display original email subject', () => {
  render(<DraftReview draft={mockDraftData} {...handlers} />);
  expect(screen.getByText('Project Proposal Discussion')).toBeInTheDocument();
});

Interaction Test

it('should call onApprove when approve button clicked', async () => {
  const onApprove = vi.fn();
  render(<DraftReview draft={mockDraftData} onApprove={onApprove} {...} />);

  const approveButton = screen.getByRole('button', { name: /approve/i });
  fireEvent.click(approveButton);

  expect(onApprove).toHaveBeenCalledWith(mockDraftData.id);
});

Edit Mode Test

it('should call onSave with edited content', async () => {
  const user = userEvent.setup();
  const onSave = vi.fn();
  render(<DraftReview {...} onSave={onSave} />);

  await user.click(screen.getByRole('button', { name: /edit/i }));
  const textarea = screen.getByRole('textbox');
  await user.clear(textarea);
  await user.type(textarea, 'Updated content');
  await user.click(screen.getByRole('button', { name: /save/i }));

  expect(onSave).toHaveBeenCalledWith(mockDraftData.id, 'Updated content');
});

TDD Workflow

Phase 1: RED ✅ COMPLETE

  • Write tests first
  • All tests fail (expected)
  • Status: Component doesn't exist

Phase 2: GREEN (NEXT)

  • Implement component
  • Watch tests turn green
  • Goal: 56/56 passing

Phase 3: REFACTOR (FUTURE)

  • Clean up code
  • Improve design
  • Keep tests passing

Getting Help

  2. Test details: See DRAFT_REVIEW_TEST_SUMMARY.txt
  3. How to implement: See DRAFT_REVIEW_IMPLEMENTATION_GUIDE.md
  4. Full context: See RED_PHASE_COMPLETE.md
  5. All details: See DELIVERABLES.md

Success Criteria

RED Phase (Current) ✅

  • Tests written and organized
  • All tests failing (expected)
  • Tests are comprehensive
  • Documentation complete
  • Ready for implementation

GREEN Phase (Next)

  • Component implemented
  • All tests passing
  • No console errors
  • Code coverage > 80%

REFACTOR Phase (After)

  • Code optimized
  • Comments added
  • Tests still passing
  • Code review passed

Running Tests

View all failing tests

npm test -- components/DraftReview.test.tsx

  • @testing-library/user-event - User interaction simulation

Mocking

  • Convex hooks mocked (useQuery, useMutation, useConvex)
  • External dependencies controlled
  • No API calls during tests

Pattern

  • AAA (Arrange-Act-Assert)
  • User-centric testing
  • Accessibility testing
  • Error case coverage

Important Concepts

What is TDD?

Test-Driven Development: Write tests before code

  1. RED: Write failing tests
  2. GREEN: Write minimal code to pass tests
  3. REFACTOR: Improve code while keeping tests passing

Why TDD?

  • Tests define behavior precisely
  • Code is written to pass tests (high quality)
  • Refactoring is safe (tests catch regressions)
  • Documentation is executable

Why All Tests Fail Now?

We're in the RED phase. The component doesn't exist yet. This is normal and correct.

Estimated Timeline

Phase Time Status
RED (testing) 2-3 hours ✅ Complete
GREEN (impl) 2.5 hours In Progress
REFACTOR 1 hour Not Started
Total 5.5 hours

Checklist for Implementation

When implementing in GREEN phase, ensure:

  • All 56 tests passing
  • No console errors
  • Proper TypeScript types
  • Tailwind styling applied
  • Component exported correctly
  • Mock data structure matches
  • All data-testids present
  • ARIA attributes correct
  • Responsive design works
  • Accessibility compliant

Questions?

Q: Why do all tests fail? A: This is RED phase of TDD. Tests are written first, component is built in GREEN phase.

Q: How do I know what to implement? A: Read the test file. Each test describes exactly what the component should do.

Q: How long will implementation take? A: Approximately 2.5 hours following the implementation guide.

Q: Can tests run in any order? A: Yes, all tests are independent. Order doesn't matter.

Q: Do I need to follow the implementation guide exactly? A: No, but following it phase-by-phase makes development easier and tests pass incrementally.
