Story Feature Implementation Report

Date: 2025-11-05 Prepared by: Product Manager Agent Sprint: Sprint 4 - Story Feature Implementation Status: Planning Complete, Ready for Implementation

Executive Summary

Current Situation

UX team has delivered comprehensive Story management design specifications (1,897 total lines across 2 documents). The design is ready for implementation. However, diagnosis reveals critical gaps in frontend implementation despite having a fully functional backend API.

Key Findings

✅ Backend Status: 100% Complete

Story CRUD API fully implemented
Multi-tenant security verified
All CQRS commands and queries ready
Authorization and validation in place

⚠️ Frontend Status: 45% Complete

Story API client: ✅ 100% (fully implemented)
Story hooks: ✅ 100% (comprehensive React Query hooks)
Story form: ✅ 70% (basic fields only, missing UX enhancements)
Story detail page: ❌ 0% (DOES NOT EXIST - 404 error)
Task management UI: ❌ 0% (no Task list, no Task creation)
Quick Add workflow: ❌ 0% (no inline form)
Kanban Story creation: ❌ 0% (no Epic card integration)

Critical Issue 🚨

Users cannot access Story details - Clicking any Story card results in 404 error because /stories/[id] route does not exist.

Recommendation

Implement Sprint 4 immediately focusing on P0/P1 priorities:

Week 1: Story Detail Page + Task Management (P0 Critical)
Week 2: Enhanced Story Form + Quick Add (P1 High)
Week 3: Story Card + Kanban Enhancement (P2 Medium, optional)

Estimated Timeline: 10-15 working days Team Required: 2 Frontend Developers + 0.5 QA Risk Level: Low (backend ready, patterns exist, UX designed)

1. Diagnosis Details

1.1 Backend API Analysis

Story API Endpoints (StoriesController.cs)

// ✅ All endpoints implemented and working
GET    /api/v1/stories/{id}                   // Get Story by ID
GET    /api/v1/epics/{epicId}/stories         // List Epic Stories
GET    /api/v1/projects/{projectId}/stories   // List Project Stories
POST   /api/v1/stories                        // Create Story
POST   /api/v1/epics/{epicId}/stories         // Create Story (nested)
PUT    /api/v1/stories/{id}                   // Update Story
DELETE /api/v1/stories/{id}                   // Delete Story (cascade)
PUT    /api/v1/stories/{id}/assign            // Assign Story

Security Status: ✅ Complete

[Authorize] attribute on all endpoints
Multi-tenant isolation verified (Day 15-16)
TenantId filters in place
JWT authentication required

CQRS Architecture: ✅ Complete

Commands: CreateStory, UpdateStory, DeleteStory, AssignStory

Epic relationship validation

Task API Endpoints (TasksController.cs)

// ✅ All endpoints implemented (assumed, needs verification)
GET    /api/v1/tasks/{id}                     // Get Task by ID
GET    /api/v1/stories/{storyId}/tasks        // List Story Tasks
POST   /api/v1/tasks                          // Create Task
PUT    /api/v1/tasks/{id}                     // Update Task
DELETE /api/v1/tasks/{id}                     // Delete Task

PUT    /api/v1/tasks/{id}/assign              // Assign Task

Note: Frontend team should verify Task endpoints on Day 1 before starting Story 2 (Task Management).

1.2 Frontend Implementation Analysis

✅ Fully Implemented Components

1. Story API Client (lib/api/pm.ts)

export const storiesApi = {
  list: async (epicId?: string): Promise<Story[]>      // ✅ Working
  get: async (id: string): Promise<Story>               // ✅ Working
  create: async (data: CreateStoryDto): Promise<Story>  // ✅ Working
  update: async (id: string, data: UpdateStoryDto)      // ✅ Working
  delete: async (id: string): Promise<void>             // ✅ Working
  changeStatus: async (id, status): Promise<Story>      // ✅ Working
  assign: async (id, assigneeId): Promise<Story>        // ✅ Working
}

Status: 100% Complete (7/7 methods) Quality: Fully typed, error handling present

2. Story Hooks (lib/hooks/use-stories.ts)

// ✅ All hooks implemented and working
useStories(epicId)              // List stories by epic
useProjectStories(projectId)    // List all project stories
useStory(id)                    // Get single story
useCreateStory()                // Create with optimistic update
useUpdateStory()                // Update with optimistic update
useDeleteStory()                // Delete with cache invalidation
useChangeStoryStatus()          // Status change with optimistic update
useAssignStory()                // Assign with cache update

Status: 100% Complete (8/8 hooks) Quality:

React Query integration complete
Optimistic updates implemented
Error handling with toast notifications
Cache invalidation strategies correct
Logger integration for debugging

3. Story Form (components/projects/story-form.tsx)

// ✅ Basic form working, needs enhancements
Fields Implemented:
✅ epicId (parent epic selector)
✅ title (required, max 200 chars)
✅ description (optional, max 2000 chars)
✅ priority (enum: Low, Medium, High, Critical)
✅ estimatedHours (optional, decimal)

Fields Missing (from UX design):
❌ acceptanceCriteria (checkbox list)
❌ assigneeId (user selector)
❌ tags (multi-select labels)
❌ storyPoints (optional, numeric)

Status: 70% Complete (5/9 fields) Quality: Zod validation, proper TypeScript types, working

4. Story Display in Epic Detail (app/(dashboard)/epics/[id]/page.tsx)

// ✅ Stories section in Epic detail page working
Features Working:
✅ Stories list display (grid layout)
✅ Story cards with metadata (status, priority, time)
✅ Create Story button → Dialog form
✅ Edit Story button → Dialog form
✅ Delete Story button → Confirmation dialog
✅ Story cards are clickable (Link to /stories/{id})

Issues:
🚨 Story link leads to 404 (route does not exist)

Status: 95% Complete (missing Story detail page route) Quality: Clean code, proper error handling, responsive

❌ Missing Implementation

1. Story Detail Page - CRITICAL ⛔

File: app/(dashboard)/stories/[id]/page.tsx
Status: DOES NOT EXIST
Impact: Users cannot access Story details (404 error)
Priority: P0 (Must fix immediately)
Estimated: 2-3 days

Required Components:

Story detail page route (/stories/[id])
Story header (title, status, priority, actions)
Story description section
Story metadata sidebar (assignee, dates, parent Epic)
Task list section (empty initially)
Edit/Delete actions
Loading and error states

Pattern to Follow: Reuse Epic detail page structure

File: app/(dashboard)/epics/[id]/page.tsx (534 lines)
Layout: Two-column (main content + sidebar)
Copy breadcrumb, header, metadata patterns
Adapt for Story context (show Tasks instead of Stories)

2. Task Management UI - CRITICAL ⛔

Components Needed:
- components/projects/task-list.tsx
- components/projects/task-card.tsx
- components/projects/task-form.tsx (inline variant)

Status: NONE EXIST
Impact: Users cannot manage Tasks within Stories
Priority: P0 (Required for Story detail page)
Estimated: 2 days

Required Features:

Task list with cards
Task checkbox for quick status toggle
Task count badge
Task filters (status, priority, assignee)
Task sorting options
"Add Task" inline form
Empty state message
Loading skeletons

3. Quick Add Story Workflow - HIGH PRIORITY

Component: components/projects/quick-add-story.tsx
Status: DOES NOT EXIST
Impact: Users must use full dialog form (slower workflow)
Priority: P1 (UX enhancement)
Estimated: 2 days

Required Features:

Inline form at top of Stories list
Minimal fields (title + priority only)
Enter key to submit
Auto-reset after creation
Keyboard shortcut (Cmd/Ctrl + N)
"Add & Create Tasks" button option

4. Story Card Component - MEDIUM PRIORITY

Component: components/projects/story-card.tsx
Status: USING INLINE CARDS (no dedicated component)
Impact: Code duplication, harder to maintain
Priority: P2 (Code quality improvement)
Estimated: 1 day

Required Features:

Three variants (list, kanban, compact)
Visual states (hover, selected, dragging)
Task count indicator
Quick actions menu
Status and priority badges
React.memo optimization

5. Kanban Story Creation - MEDIUM PRIORITY

Enhancement: Epic card in Kanban Board
Status: NO STORY CREATION FROM KANBAN
Impact: Users cannot create Stories contextually
Priority: P2 (Nice to have)
Estimated: 2 days

Required Features:

"+ Add Story" button on Epic card hover
Inline Story form below Epic card
Context-bound (Epic pre-selected)
Real-time Epic Story count update

6. Activity Timeline - LOW PRIORITY

Component: components/shared/activity-timeline.tsx

2. UX Design Review

2.1 Design Documentation

Primary Document: docs/designs/STORY_UX_UI_DESIGN.md

Length: 1,409 lines (73KB)
Completeness: 100% (production-ready specification)
Quality: Excellent (detailed wireframes, interactions, accessibility)

Summary Document: docs/designs/STORY_DESIGN_SUMMARY.md

Length: 488 lines (26KB)
Purpose: Quick reference and executive overview

Total Design Investment: 1,897 lines (99KB) of comprehensive UX specifications

2.2 Key Design Decisions

1. Story Detail Page Layout

Decision: Two-column layout (main content + metadata sidebar)

┌────────────────────────────────────────────────────────┐
│ [Breadcrumb] [←] Story Title    [Edit][Delete]         │
├────────────────────────────────────────────────────────┤
│ ┌─────────────────────┐  ┌──────────────────────────┐ │
│ │ Story Details       │  │ Metadata Sidebar         │ │
│ │ - Description       │  │ - Status, Priority       │ │
│ │ - Acceptance Crit.  │  │ - Assignee               │ │
│ │ - Tasks (8)         │  │ - Time Tracking          │ │
│ │ - Activity Timeline │  │ - Parent Epic Card       │ │
│ └─────────────────────┘  └──────────────────────────┘ │
└────────────────────────────────────────────────────────┘

Rationale:

Consistent with Epic detail page design
Separates core content from metadata
Optimizes for 80% use case (reading details)
Responsive: Sidebar moves to top on mobile

2. Story Creation Flow

Decision: Hybrid approach (Quick Add + Full Form)

Quick Add (Inline):

For rapid Story creation
Title + Priority only
Inline form at top of Stories section
Keyboard shortcut: Cmd/Ctrl + N
Auto-reset for batch creation

Full Form (Dialog):

For detailed Stories
All fields available (description, assignee, acceptance criteria)
Accessed via [+ New Story] button
Used when planning requires more detail

Rationale:

Supports both quick workflows and detailed planning
Reduces clicks for common case (simple Story)
Maintains consistency with Epic creation pattern

3. Task Management

Decision: Expandable Task list with inline creation

Features:

Checkbox for quick status toggle
Filters: Status, Priority, Assignee
Sort: Priority, Status, Date, Assignee
Inline "Add Task" form
Task count badge in header
Empty state with guidance

Rationale:

Tasks are critical to Story completion
Users need quick Task updates without navigation
Aligns with "Flow" principle (minimize steps)

4. Kanban Enhancement

Decision: Add contextual Story creation from Epic cards

Interaction:

Hover over Epic card → [+ Add Story] button appears
Click → Inline Story form opens below Epic card
Create → Story appears in correct Kanban column

Rationale:

Reduces navigation (no need to open Epic detail)
Maintains context (Epic visible while creating)
Faster workflow for batch Story creation

4. Technical Considerations

4.1 Code Reuse Strategy

Epic Pattern Reuse (60% code reuse):

Epic Component	Story Equivalent	Reuse %	Notes
Epic detail page	Story detail page	80%	Change Stories list → Task list
Epic header	Story header	90%	Same structure, different labels
Epic metadata	Story metadata	85%	Add acceptance criteria field
Epic form	Story form	70%	Already exists, needs enhancements
Epic card	Story card	80%	Change Story count → Task count

Benefits:

Consistency: Users see familiar patterns
Speed: 50-60% faster development
Quality: Proven patterns, fewer bugs
Maintenance: Shared components easier to update

Example: Epic Detail Page → Story Detail Page

// Epic Detail Page Structure
app/(dashboard)/epics/[id]/page.tsx
├── Breadcrumb (Projects > Project > Epics > Epic)
├── Header (Title, Status, Priority, Actions)
├── Two-column layout
│   ├── Main Content
│   │   ├── Description
│   │   ├── Metadata (Time, Dates)
│   │   └── Stories List ← REPLACE WITH TASKS
│   └── Sidebar
│       ├── Status/Priority
│       ├── Assignee
│       ├── Time Tracking
│       └── Parent Project ← REPLACE WITH PARENT EPIC

// Story Detail Page Structure (to create)
app/(dashboard)/stories/[id]/page.tsx
├── Breadcrumb (Projects > Project > Epics > Epic > Stories > Story)
├── Header (Title, Status, Priority, Actions)
├── Two-column layout
│   ├── Main Content
│   │   ├── Description
│   │   ├── Acceptance Criteria (NEW)
│   │   ├── Metadata (Time, Dates)

Code Reuse Steps:

Copy epics/[id]/page.tsx → stories/[id]/page.tsx
Replace useEpic → useStory
Replace useStories → useTasks
Update breadcrumb (add Story level)
Change Stories section → Tasks section
Add acceptance criteria section
Update sidebar (Parent Project → Parent Epic)
Test all interactions

components/ui/ (if needed)
├── tag-selector.tsx            # Multi-select tags
└── keyboard-shortcut.tsx       # Global shortcut handler

Component Specifications:

1. StoryCard Component

interface StoryCardProps {
  story: Story;
  variant: 'list' | 'kanban' | 'compact';
  showActions?: boolean;
  onEdit?: (story: Story) => void;
  onDelete?: (storyId: string) => void;
  onStatusChange?: (storyId: string, status: WorkItemStatus) => void;
}

// Visual States
- default
- hover (border-primary, shadow)
- selected (bg-primary-50)
- dragging (opacity-50, rotate-2deg)

2. TaskList Component

interface TaskListProps {
  storyId: string;
  tasks: Task[];
  readonly?: boolean;
  onTaskCreate?: () => void;
  onTaskUpdate?: (task: Task) => void;
  onTaskDelete?: (taskId: string) => void;
  onTaskReorder?: (taskId: string, newOrder: number) => void;
}

// Features
- Expandable Task cards
- Checkbox status toggle
- Filters (status, priority, assignee)
- Sort options
- Drag to reorder (Phase 3)
- Bulk operations (Phase 4)

3. QuickAddStory Component

interface QuickAddStoryProps {
  epicId: string;
  projectId: string;
  onSuccess?: (story: Story) => void;
  onCancel?: () => void;
}

// Features
- Minimal form (title + priority)
- Enter key submit
- Auto-reset after creation
- Keyboard shortcut (Cmd/Ctrl + N)
- "Add & Create Tasks" button

4.3 State Management

React Query Cache Structure:

// Query Keys
['stories', epicId]                // List of stories by epic
['stories', storyId]               // Single story detail
['project-stories', projectId]     // All project stories
['tasks', storyId]                 // List of tasks by story
['tasks', taskId]                  // Single task detail

// Cache Invalidation Strategy
Create Story → Invalidate:
  - ['stories', epicId]
  - ['epics', epicId] (update story count)

Update Story → Invalidate:
  - ['stories', storyId]
  - ['stories', epicId]

Delete Story → Invalidate:
  - ['stories', epicId]
  - ['epics', epicId]
  - Remove ['stories', storyId]

Create Task → Invalidate:
  - ['tasks', storyId]
  - ['stories', storyId] (update task count)

Update Task → Invalidate:
  - ['tasks', taskId]
  - ['tasks', storyId]

Delete Task → Invalidate:
  - ['tasks', storyId]
  - ['stories', storyId]
  - Remove ['tasks', taskId]

Optimistic Updates:

// Story Status Change (already implemented)
useChangeStoryStatus() {
  onMutate: async ({ id, status }) => {
    // Cancel queries
    await queryClient.cancelQueries(['stories', id]);

    // Snapshot previous
    const previous = queryClient.getQueryData(['stories', id]);

    // Optimistically update
    queryClient.setQueryData(['stories', id], (old) => ({
      ...old,
      status
    }));

    return { previous };
  },

  onError: (err, vars, context) => {
    // Revert on error
    queryClient.setQueryData(['stories', vars.id], context.previous);
  }
}

// Task Status Change (to implement)
useChangeTaskStatus() {
  // Same pattern as Story status change
}

4.4 TypeScript Types

Existing Types (types/project.ts):

// ✅ Already defined
export interface Story {
  id: string;
  title: string;
  description?: string;
  epicId: string;
  projectId: string;
  status: WorkItemStatus;
  priority: WorkItemPriority;
  estimatedHours?: number;
  actualHours?: number;
  assigneeId?: string;
  tenantId: string;
  createdAt: string;
  updatedAt: string;
}

export interface CreateStoryDto {
  epicId: string;
  projectId: string;
  title: string;
  description?: string;
  priority: WorkItemPriority;
  estimatedHours?: number;
  createdBy: string;
}

export interface UpdateStoryDto {
  title?: string;
  description?: string;
  priority?: WorkItemPriority;
  estimatedHours?: number;
  actualHours?: number;
}

New Types Needed (Story 3: Enhanced Form):

// Add to Story interface
export interface Story {
  // ... existing fields
  acceptanceCriteria?: AcceptanceCriterion[];  // NEW
  tags?: string[];                              // NEW
  storyPoints?: number;                         // NEW
}

export interface AcceptanceCriterion {
  id: string;
  text: string;
  completed: boolean;
}

// Add to CreateStoryDto
export interface CreateStoryDto {
  // ... existing fields
  acceptanceCriteria?: AcceptanceCriterion[];  // NEW
  tags?: string[];                              // NEW
  storyPoints?: number;                         // NEW
}

// Add to UpdateStoryDto
export interface UpdateStoryDto {
  // ... existing fields
  acceptanceCriteria?: AcceptanceCriterion[];  // NEW
  tags?: string[];                              // NEW
  storyPoints?: number;                         // NEW
}

Task Types (types/project.ts):

// ✅ Already defined
export interface Task {
  id: string;
  title: string;
  description?: string;
  storyId: string;
  projectId: string;
  status: WorkItemStatus;
  priority: WorkItemPriority;
  estimatedHours?: number;
  actualHours?: number;
  assigneeId?: string;
  tenantId: string;
  createdAt: string;
  updatedAt: string;
}

export interface CreateTaskDto {
  storyId: string;
  title: string;
  description?: string;
  priority: WorkItemPriority;
  estimatedHours?: number;
}

export interface UpdateTaskDto {
  title?: string;
  description?: string;
  priority?: WorkItemPriority;
  estimatedHours?: number;
  actualHours?: number;
}

4.5 Performance Considerations

React.memo Optimization (from Sprint 3):

// All list components should use React.memo
export const StoryCard = React.memo(function StoryCard(props: StoryCardProps) {
  // ... component code
}, (prevProps, nextProps) => {
  // Custom comparison: only re-render if story changed
  return prevProps.story.id === nextProps.story.id &&
         prevProps.story.status === nextProps.story.status &&
         prevProps.story.priority === nextProps.story.priority &&
         prevProps.story.title === nextProps.story.title;
});

export const TaskCard = React.memo(function TaskCard(props: TaskCardProps) {
  // ... component code
});

useCallback for Event Handlers:

// In Story detail page
const handleEditStory = useCallback(() => {
  setIsEditDialogOpen(true);
}, []);

const handleDeleteStory = useCallback(async () => {
  await deleteStory.mutateAsync(storyId);
}, [storyId, deleteStory]);

const handleTaskStatusChange = useCallback(async (taskId: string, status: WorkItemStatus) => {
  await changeTaskStatus.mutateAsync({ taskId, status });
}, [changeTaskStatus]);

Lazy Loading (if needed):

// Lazy load Activity Timeline (Phase 5)
const ActivityTimeline = lazy(() => import('@/components/shared/activity-timeline'));

// Use with Suspense
<Suspense fallback={<Skeleton className="h-64" />}>
  <ActivityTimeline entityType="story" entityId={storyId} />
</Suspense>

Virtual Scrolling (Phase 3, for large Task lists):

// Use react-window for Task lists > 50 items
import { FixedSizeList } from 'react-window';

<FixedSizeList
  height={600}
  itemCount={tasks.length}
  itemSize={80}
  width="100%"
>
  {({ index, style }) => (
    <div style={style}>
      <TaskCard task={tasks[index]} />
    </div>
  )}
</FixedSizeList>

4.6 Accessibility Implementation

ARIA Labels (from UX design):

// Story Card
<article
  role="article"
  aria-labelledby={`story-title-${story.id}`}
  aria-describedby={`story-desc-${story.id}`}
>
  <h3 id={`story-title-${story.id}`}>{story.title}</h3>

  <div aria-label={`Status: ${story.status}`}>
    <span className="sr-only">Status:</span>
    <Badge>{story.status}</Badge>
  </div>

  <p id={`story-desc-${story.id}`} className="sr-only">
    {story.description}
  </p>
</article>

// Task Checkbox
<input
  type="checkbox"
  id={`task-${task.id}`}
  aria-labelledby={`task-title-${task.id}`}
  aria-describedby={`task-meta-${task.id}`}
  checked={task.status === 'Done'}
  onChange={handleTaskStatusChange}
/>

<label htmlFor={`task-${task.id}`}>
  <span id={`task-title-${task.id}`}>{task.title}</span>
</label>

<div id={`task-meta-${task.id}`} className="sr-only">
  Priority: {task.priority}, Assignee: {task.assigneeId},
  Estimated: {task.estimatedHours} hours
</div>

Keyboard Navigation:

// Global keyboard shortcuts (Story 4)
useEffect(() => {
  const handleKeyDown = (e: KeyboardEvent) => {
    // Cmd/Ctrl + N: Quick Add Story
    if ((e.metaKey || e.ctrlKey) && e.key === 'n') {
      e.preventDefault();
      setQuickAddOpen(true);
    }

    // ESC: Close dialog
    if (e.key === 'Escape') {
      setQuickAddOpen(false);
      setIsEditDialogOpen(false);
    }
  };

  window.addEventListener('keydown', handleKeyDown);
  return () => window.removeEventListener('keydown', handleKeyDown);
}, []);

Focus Management:

// When opening dialog, focus on first field
useEffect(() => {
  if (isEditDialogOpen) {
    const titleInput = document.getElementById('story-title');
    titleInput?.focus();
  }
}, [isEditDialogOpen]);

// When closing dialog, return focus to trigger
const returnFocusRef = useRef<HTMLButtonElement>(null);

const handleOpenDialog = () => {
  returnFocusRef.current = document.activeElement as HTMLButtonElement;
  setIsEditDialogOpen(true);
};

const handleCloseDialog = () => {
  setIsEditDialogOpen(false);
  returnFocusRef.current?.focus();
};

4.7 Testing Strategy

Unit Tests (Jest + React Testing Library):

// Story Card Component Tests
describe('StoryCard', () => {
  it('renders story title and metadata', () => {
    render(<StoryCard story={mockStory} variant="list" />);
    expect(screen.getByText(mockStory.title)).toBeInTheDocument();
    expect(screen.getByText(mockStory.status)).toBeInTheDocument();
  });

  it('calls onEdit when edit button clicked', () => {
    const onEdit = jest.fn();
    render(<StoryCard story={mockStory} variant="list" onEdit={onEdit} />);
    fireEvent.click(screen.getByRole('button', { name: /edit/i }));
    expect(onEdit).toHaveBeenCalledWith(mockStory);
  });

  it('shows hover state on mouse over', () => {
    const { container } = render(<StoryCard story={mockStory} variant="list" />);
    const card = container.firstChild;
    fireEvent.mouseEnter(card);
    expect(card).toHaveClass('hover:border-primary');
  });
});

// Task List Component Tests
describe('TaskList', () => {
  it('renders empty state when no tasks', () => {
    render(<TaskList storyId="123" tasks={[]} />);
    expect(screen.getByText(/No tasks yet/i)).toBeInTheDocument();
  });

  it('renders task cards for each task', () => {
    render(<TaskList storyId="123" tasks={mockTasks} />);
    expect(screen.getAllByRole('article')).toHaveLength(mockTasks.length);
  });

  it('calls onTaskCreate when Add Task clicked', () => {
    const onTaskCreate = jest.fn();
    render(<TaskList storyId="123" tasks={[]} onTaskCreate={onTaskCreate} />);
    fireEvent.click(screen.getByRole('button', { name: /add task/i }));
    expect(onTaskCreate).toHaveBeenCalled();
  });
});

// Quick Add Story Tests
describe('QuickAddStory', () => {
  it('submits form on Enter key', async () => {
    const onSuccess = jest.fn();
    render(<QuickAddStory epicId="123" projectId="456" onSuccess={onSuccess} />);

    const titleInput = screen.getByPlaceholderText(/story title/i);
    fireEvent.change(titleInput, { target: { value: 'New Story' } });
    fireEvent.keyDown(titleInput, { key: 'Enter' });

    await waitFor(() => {
      expect(onSuccess).toHaveBeenCalled();
    });
  });

  it('resets form after successful creation', async () => {
    render(<QuickAddStory epicId="123" projectId="456" />);

    const titleInput = screen.getByPlaceholderText(/story title/i);
    fireEvent.change(titleInput, { target: { value: 'New Story' } });
    fireEvent.click(screen.getByRole('button', { name: /add story/i }));

    await waitFor(() => {
      expect(titleInput).toHaveValue('');
    });
  });
});

Integration Tests (Playwright E2E):

// Story Detail Page E2E Test
test('user can view story details and manage tasks', async ({ page }) => {
  // Navigate to Story detail page
  await page.goto('/stories/story-123');

  // Verify Story details displayed
  await expect(page.locator('h1')).toContainText('Login Feature');
  await expect(page.locator('[data-testid="story-status"]')).toContainText('In Progress');

  // Create a new Task
  await page.click('[data-testid="add-task-button"]');
  await page.fill('[name="title"]', 'Implement login form');
  await page.selectOption('[name="priority"]', 'High');
  await page.click('[data-testid="submit-task"]');

  // Verify Task appears in list
  await expect(page.locator('[data-testid="task-item"]')).toContainText('Implement login form');

  // Toggle Task status
  await page.click('[data-testid="task-checkbox"]');
  await expect(page.locator('[data-testid="task-status"]')).toContainText('Done');

  // Verify Task count updated
  await expect(page.locator('[data-testid="task-count"]')).toContainText('1');
});

// Quick Add Story E2E Test
test('user can quickly add multiple stories', async ({ page }) => {
  await page.goto('/epics/epic-123');

  // Click Quick Add button
  await page.click('[data-testid="quick-add-button"]');

  // Add first Story
  await page.fill('[name="title"]', 'Story 1');
  await page.selectOption('[name="priority"]', 'High');
  await page.press('[name="title"]', 'Enter');

  // Verify Story 1 appears
  await expect(page.locator('[data-testid="story-item"]')).toContainText('Story 1');

  // Add second Story (form should reset)
  await page.fill('[name="title"]', 'Story 2');
  await page.press('[name="title"]', 'Enter');

  // Verify Story 2 appears
  await expect(page.locator('[data-testid="story-item"]')).toContainText('Story 2');
});

// Keyboard Shortcut E2E Test
test('keyboard shortcut opens quick add form', async ({ page }) => {
  await page.goto('/epics/epic-123');

  // Press Cmd/Ctrl + N
  await page.keyboard.press(process.platform === 'darwin' ? 'Meta+N' : 'Control+N');

  // Verify Quick Add form appears
  await expect(page.locator('[data-testid="quick-add-form"]')).toBeVisible();

  // Press ESC to close
  await page.keyboard.press('Escape');
