Project Overview

Sprint Burn-up Chart

We tracked our progress meticulously throughout the sprint. The chart below illustrates our team's velocity in completing the task management user stories against our estimated timeline.

SCRUM table

1. Project Background and Objectives

1.1 Project Background

In the previous Alpha phase, tasks were displayed in a list format, resulting in a somewhat monotonous user experience. Based on user feedback, we identified the following areas for improvement:

• Insufficient Visualization: Task lists made it difficult to intuitively display task priority and progress status
• Lack of Interaction: Task status transitions were not intuitive enough

Based on these observations, in the third phase of the Beta sprint, we focused on:

• Converting task lists into visual cards
• Implementing in-place editing functionality
• Optimizing task status management

1.2 Objectives

1.2.1 Implemented Features:

1. Support task modification
2. Support changing the task to a card format, which would be more intuitive
3. Fix bug: The time on the task list does not match the time set by the user

1.2.2 Specific Implementation:

1. Task Card Template (task_card.html)

• Reusable Component: Independent template for consistent task display across pages
• Data Binding: Uses Jinja2 to dynamically render task data (title, description, due date)
• Metadata Storage: Employs data-* attributes to store task metadata (priority, status, ID) for JavaScript access
• Conditional Display: Shows content only when available (e.g., description, course)
• Interactive Elements: Includes edit/delete buttons and checkbox for status updates
• Visual Status: Dynamically styles completed tasks with strikethrough

2. Task Modification Backend (app.py)

• Unified Route: Single /tasks/add endpoint handles both creation and editing
• Security Checks: Validates user authentication and task ownership
• Data Processing: Converts and validates form inputs
• Transaction Safety: Uses database transactions for data consistency
• User Feedback: Returns success/failure messages after operations

3. Task Modification Frontend (main.js)

• DOM Interaction: Finds task cards by ID and extracts displayed data
• Modal Integration: Populates edit modal with task data for seamless editing
• Date Handling: Converts user-friendly dates to database-compatible ISO format
• Event-Driven: Triggers edit functionality on button clicks
• Error Management: Handles edge cases like missing task cards

4. Task Card Styling (style.css)

• Modern Design: Uses rounded corners, shadows, and gradients for a card-based UI
• Priority Visualization: Shows colored side bars based on priority
• Hover Effects: Implements subtle animations for interactivity
• Responsive Layout: Ensures consistent display across screen sizes
• Content Optimization: Truncates long text to maintain clean appearance

5. Bug Fixes: Fixed the time display inconsistency bug

2. Git Repository and Coding Standards

• Git Repository: FocusFlow
• Coding Standards: FocusFlow β Sprint Code Standards

6. Test Case Design

1. Functional Test Cases

def test_forgot_password_flow():
    # Test normal flow
    test_phone = "17840904445"
    
    # Step 1: Enter phone number
    response = client.post('/verify_phone', json={'phone': test_phone})
    assert response.status_code == 200
    assert response.json['success'] == True
    
    # Step 2: Verify countdown function
    # Simulate 10-second wait
    import time
    time.sleep(10)
    
    # Step 3: Reset password
    new_password = "newpassword123"
    response = client.post('/reset_password', json={
        'phone': test_phone,
        'new_password': new_password,
        'confirm_password': new_password
    })
    assert response.status_code == 200
    assert response.json['success'] == True

2. Edge Case Testing

• Invalid phone number handling
• User not found scenarios
• Network timeout retry mechanism
• Concurrent request handling

7. Deployment and Monitoring

1. Log Monitoring

@app.route('/reset_password', methods=['POST'])
def reset_password():
    logger.info(f"Password reset request for phone: {data.get('phone')}")
    
    try:
        # Reset logic...
        logger.info("Password reset successful")
        return jsonify({'success': True, 'message': 'Password reset successfully'})
    except Exception as e:
        logger.error(f"Password reset failed: {str(e)}")
        return jsonify({'success': False, 'message': 'Reset failed'})

2. Performance Monitoring Metrics

• Average response time < 80ms
• Error rate < 1%
• Concurrent user support > 100

8. Summary

In Beta Sprint Phase 3, we successfully transformed FocusFlow's task management system from a basic list view to an intuitive card-based interface. This major redesign included adding estimated time tracking, in-place editing features, and significant performance improvements that enhanced both user experience and system efficiency.
