​
Testing Philosophy

AniDojo emphasizes quality through comprehensive testing. While the project is currently in active development, we’re building a robust testing foundation to ensure reliability as features grow.

​
Testing Strategy

​
Current Approach

AniDojo currently focuses on:
  • Manual Testing - Thorough browser testing during development
  • TypeScript Type Checking - Compile-time error prevention
  • ESLint - Code quality and best practice enforcement
  • Browser Testing - Real-world usage testing across devices
Automated testing infrastructure is planned for future releases. The foundation is being built to support unit, integration, and E2E tests.

​
Development Testing Workflow

1

Run the Development Server

Start the development server with Turbopack for hot reloading:
npm run dev
The app will be available at http://localhost:3000
2

Test in the Browser

Manually test your changes:
  • Navigate through affected pages
  • Test user interactions (clicks, forms, navigation)
  • Check responsive design on different screen sizes
  • Verify animations and transitions
  • Test edge cases and error states
3

Run Type Checking

Verify TypeScript types compile correctly:
npx tsc --noEmit
This ensures type safety without emitting files.
4

Run ESLint

Check code quality and fix issues:
npm run lint
5

Build for Production

Ensure the production build succeeds:
npm run build
The build process catches many issues that might not appear in development mode.

​
TypeScript as a Testing Tool

​
Type Safety Benefits

TypeScript catches many bugs at compile time: 
interface Anime {
  id: string;
  title: string;
  episodes: number;
}

// TypeScript will catch this error
const anime: Anime = {
  id: '1',
  title: 'Naruto',
  // Missing 'episodes' property - compile error!
};

​
Strict Mode Configuration

AniDojo uses strict TypeScript settings: 
{
  "compilerOptions": {
    "strict": true,
    "noEmit": true,
    "skipLibCheck": true
  }
}
This enables:
  • strictNullChecks - Prevent null/undefined errors
  • strictFunctionTypes - Type-safe function parameters
  • noImplicitAny - Require explicit types
  • noImplicitThis - Prevent this context errors

​
Manual Testing Checklist

When testing new features or changes, verify:

​
Functionality

  • Feature works as expected
  • All user interactions respond correctly
  • Navigation works between pages
  • Forms validate and submit properly
  • Data displays correctly

​
UI/UX

  • Layout is correct on desktop
  • Layout is correct on mobile devices
  • Layout is correct on tablets
  • Dark theme displays properly
  • Animations and transitions are smooth
  • Loading states display appropriately

​
Error Handling

  • Error messages display correctly
  • Invalid input is handled gracefully
  • Network errors are caught
  • 404 pages work correctly
  • Fallback UI displays when needed

​
Performance

  • Pages load quickly
  • No console errors or warnings
  • Images load properly
  • No layout shift during load
  • Smooth scrolling and interactions

​
Accessibility

  • Keyboard navigation works
  • Focus indicators are visible
  • Semantic HTML is used
  • Alt text on images
  • Proper heading hierarchy

​
Browser Testing

Test your changes in:
  • Chrome - Primary development browser
  • Firefox - Cross-browser compatibility
  • Safari - WebKit engine testing
  • Edge - Chromium-based alternative

​
Responsive Testing

Test at these breakpoints: 
/* Mobile */
@media (max-width: 640px)

/* Tablet */
@media (min-width: 641px) and (max-width: 1024px)

/* Desktop */
@media (min-width: 1025px)
Use browser DevTools device emulation to test different screen sizes and devices.

​
Future Testing Plans

​
Unit Testing

Planned setup with Jest or Vitest: 
// Example unit test (future)
import { render, screen } from '@testing-library/react';
import { AnimeCard } from '@/components/AnimeCard';

describe('AnimeCard', () => {
  it('renders anime title', () => {
    render(<AnimeCard title="Naruto" imageUrl="/naruto.jpg" rating={8.5} />);
    expect(screen.getByText('Naruto')).toBeInTheDocument();
  });
  
  it('displays rating correctly', () => {
    render(<AnimeCard title="Naruto" imageUrl="/naruto.jpg" rating={8.5} />);
    expect(screen.getByText('8.5')).toBeInTheDocument();
  });
});

​
Integration Testing

Planned tests for component interactions: 
// Example integration test (future)
import { render, screen, fireEvent } from '@testing-library/react';
import { SearchBar } from '@/components/SearchBar';

describe('SearchBar Integration', () => {
  it('filters anime list on search', async () => {
    render(<AnimeListPage />);
    
    const searchInput = screen.getByPlaceholderText('Search anime...');
    fireEvent.change(searchInput, { target: { value: 'Naruto' } });
    
    // Verify filtered results
    expect(screen.getByText('Naruto')).toBeInTheDocument();
    expect(screen.queryByText('One Piece')).not.toBeInTheDocument();
  });
});

​
End-to-End Testing

Planned E2E tests with Playwright: 
// Example E2E test (future)
import { test, expect } from '@playwright/test';

test('user can browse and view anime details', async ({ page }) => {
  await page.goto('http://localhost:3000');
  
  // Navigate to browse page
  await page.click('text=Browse');
  await expect(page).toHaveURL(/.*browse/);
  
  // Click on first anime
  await page.click('.anime-card:first-child');
  
  // Verify details page loaded
  await expect(page.locator('h1')).toBeVisible();
});

​
Testing Best Practices

1

Test Early and Often

Don’t wait until the end to test. Test as you develop.
2

Test Real User Flows

Think like a user. Test complete workflows, not just individual functions.
3

Test Edge Cases

Don’t just test the happy path. Try invalid inputs, empty states, and error conditions.
4

Document Issues

When you find a bug, document it clearly with steps to reproduce.
5

Fix Breaking Changes

If you introduce a breaking change, update affected code and documentation.

​
Continuous Integration

​
Build Verification

Production builds run automatically in CI: 
# Example CI workflow (future)
name: CI
on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
      - run: npm install
      - run: npm run lint
      - run: npx tsc --noEmit
      - run: npm run build

​
Code Quality Gates

Before merging code, ensure:
  1. TypeScript compiles without errors
  2. ESLint passes with no warnings
  3. Build succeeds in production mode
  4. Manual testing completed
  5. PR review approved by maintainer
As the project grows, additional automated testing will be added to catch regressions and ensure consistent quality.

​
Reporting Bugs

When you find a bug:
  1. Check if it’s already reported in GitHub issues
  2. Create a new issue with:
    • Clear description of the problem
    • Steps to reproduce
    • Expected vs actual behavior
    • Browser and environment details
    • Screenshots if applicable
  3. Label appropriately (bug, critical, etc.)
