This document outlines the testing approach for the IdeaScore application. Testing will be integrated throughout the development process to ensure quality and reliability.

1. Ensure all features work as specified in user stories
2. Verify data isolation between applications
3. Confirm proper authentication and authorization
4. Validate UI responsiveness across devices
5. Verify performance under various load conditions
6. Ensure compatibility with major browsers

Unit tests focus on individual functions and components to ensure they work correctly in isolation.

Key Areas to Test:

• Database utility functions
• Form validation logic
• Data transformation functions
• Sorting and filtering algorithms
• Score calculations

Example Unit Tests:

// Example test for the ratio calculation function
test('calculateRatio should handle various inputs correctly', () => {
  expect(calculateRatio(10, 5)).toBe(2);       // Normal case
  expect(calculateRatio(0, 5)).toBe(0);        // Edge case: zero payoff
  expect(calculateRatio(10, 0)).toBe(Infinity); // Edge case: zero effort
  expect(calculateRatio(null, 5)).toBe(0);     // Edge case: null payoff
});

Integration tests verify that different parts of the application work together correctly.

Key Areas to Test:

• Form submission to database flow
• Data retrieval and display
• Authentication integration
• Sorting and filtering implementation
• Chart data generation

Example Integration Tests:

// Example test for idea creation flow
test('Creating a new idea should store it in the database and appear in the list', async () => {
  // Submit form with test data
  await submitIdeaForm({
    title: 'Test Idea',
    description: 'Test Description',
    effortScore: 5,
    payoffScore: 8
  });
  
  // Verify the idea appears in the database
  const ideas = await getIdeas('test@example.com');
  const newIdea = ideas.find(idea => idea.title === 'Test Idea');
  
  expect(newIdea).toBeDefined();
  expect(newIdea.effort_score).toBe(5);
  expect(newIdea.payoff_score).toBe(8);
  
  // Verify the idea appears in the UI
  const ideaElements = document.querySelectorAll('.idea-item');
  const uiIdea = Array.from(ideaElements).find(el => 
    el.querySelector('.idea-title').textContent === 'Test Idea'
  );
  
  expect(uiIdea).toBeDefined();
});

UI tests verify that the user interface works correctly and provides a good user experience.

Key Areas to Test:

• Form validation and feedback
• Responsive design on different screen sizes
• Sorting and filtering controls
• Navigation between views
• Error states and edge cases

Example UI Tests:

// Example test for form validation
test('Idea form should validate required fields', async () => {
  // Try to submit the form without required fields
  await clickElement('#submit-button');
  
  // Check for error messages
  expect(document.querySelector('#title-error')).toBeVisible();
  expect(document.querySelector('#effort-score-error')).toBeVisible();
  expect(document.querySelector('#payoff-score-error')).toBeVisible();
  
  // Fill out one field and check that only its error is cleared
  await typeIntoInput('#title-input', 'Test Idea');
  expect(document.querySelector('#title-error')).not.toBeVisible();
  expect(document.querySelector('#effort-score-error')).toBeVisible();
});

Data isolation tests verify that data from one application or user doesn't leak into another.

Key Areas to Test:

• Multi-user data isolation
• Cross-application data isolation
• Authorization checks

Example Data Isolation Tests:

// Example test for user data isolation
test('Users should only see their own ideas', async () => {
  // Create ideas for two different users
  await createIdeaForUser('user1@example.com', {
    title: 'User 1 Idea',
    effortScore: 5,
    payoffScore: 7
  });
  
  await createIdeaForUser('user2@example.com', {
    title: 'User 2 Idea',
    effortScore: 3,
    payoffScore: 8
  });
  
  // Log in as user1 and verify they only see their ideas
  await loginAs('user1@example.com');
  const user1Ideas = await getDisplayedIdeas();
  
  expect(user1Ideas.some(idea => idea.title === 'User 1 Idea')).toBe(true);
  expect(user1Ideas.some(idea => idea.title === 'User 2 Idea')).toBe(false);
  
  // Log in as user2 and verify they only see their ideas
  await loginAs('user2@example.com');
  const user2Ideas = await getDisplayedIdeas();
  
  expect(user2Ideas.some(idea => idea.title === 'User 1 Idea')).toBe(false);
  expect(user2Ideas.some(idea => idea.title === 'User 2 Idea')).toBe(true);
});

Performance tests verify that the application performs well under various conditions.

Key Areas to Test:

• Load times with many ideas
• Sorting and filtering performance
• Chart rendering with large datasets
• Database query optimization

Example Performance Tests:

// Example test for list performance with many ideas
test('Idea list should render quickly with 100+ ideas', async () => {
  // Create 100+ test ideas
  await createBulkIdeas(100);
  
  // Measure render time
  const startTime = performance.now();
  await navigateToIdeaList();
  const endTime = performance.now();
  
  // Verify render time is acceptable (e.g., under 500ms)
  expect(endTime - startTime).toBeLessThan(500);
  
  // Verify all ideas are eventually loaded (might be paginated)
  expect(document.querySelectorAll('.idea-item').length).toBeGreaterThan(0);
});

Accessibility tests verify that the application is usable by people with disabilities.

Key Areas to Test:

• Keyboard navigation
• Screen reader compatibility
• Color contrast
• Text scaling
• Focus management

Example Accessibility Tests:

// Example test for keyboard navigation
test('Users should be able to navigate the idea list with keyboard', async () => {
  await navigateToIdeaList();
  
  // Tab to the first idea
  await pressTab();
  expect(document.activeElement.closest('.idea-item')).toBeDefined();
  
  // Tab to the edit button
  await pressTab();
  expect(document.activeElement.textContent).toBe('Edit');
  
  // Tab to the delete button
  await pressTab();
  expect(document.activeElement.textContent).toBe('Delete');
  
  // Tab to the next idea
  await pressTab();
  expect(document.activeElement.closest('.idea-item')).toBeDefined();
});

For the IdeaScore application, we'll use a lightweight testing approach that works well within the Val Town environment:

1. Unit Testing: Simple utility for testing individual functions
2. Integration Testing: Custom test harness for testing database operations
3. UI Testing: Manual testing with a checklist for each checkpoint
4. Data Isolation Testing: Custom scripts to verify isolation between users/applications
5. Accessibility Testing: Combination of automated tools and manual checks

Tests will be organized according to the checkpoints in the development roadmap. Each checkpoint will have associated tests that must pass before proceeding to the next checkpoint.

/projects/ideaScore/tests/
├── unit/                  # Unit tests for utility functions
├── integration/           # Integration tests for features
├── ui/                    # UI testing checklists
├── test-utils.js          # Shared testing utilities
└── test-runner.js         # Simple test runner

1. Development: Write tests alongside or before implementation (TDD when possible)
2. Checkpoint Testing: Run all tests for the checkpoint before requesting review
3. Regression Testing: Run all previous tests when making significant changes
4. Manual Testing: Follow UI testing checklist for each feature
5. Documentation: Document test results and any issues found

A checkpoint is considered successfully tested when:

1. All unit tests pass
2. All integration tests pass
3. UI testing checklist is completed with no issues
4. Data isolation is verified
5. No accessibility issues are found

The testing strategy will evolve as the project progresses:

1. Add more automated tests as the application grows
2. Refine testing approaches based on discovered issues
3. Improve testing tools and frameworks as needed
4. Update testing documentation regularly

This testing strategy provides a framework for ensuring the quality of the IdeaScore application throughout its development lifecycle.
