Testing Strategy Summary

Created by: Hive Mind - Tester Agent Date: 2025-11-27 Status: Ready for Implementation

Executive Summary

This document provides a comprehensive automated testing strategy for the Manacore monorepo, designed to achieve 80% test coverage for new code while maintaining development velocity. The strategy includes test frameworks, configurations, examples, and CI/CD integration for all app types in the monorepo.

Current State

Test Coverage Analysis

• Total Test Files: 25 (across entire monorepo)
• Current Coverage: Sparse (~5% estimated)
• Target Coverage: 80% for new code, 100% for critical paths

Existing Tests by Project

Project	Backend	Mobile	Web	Total
Maerchenzauber	8	5	0	13
Memoro	0	3	0	3
Uload	0	0	9	9
Total	8	8	9	25

Strengths

✅ Maerchenzauber mobile has excellent auth test patterns ✅ Uload web demonstrates good Vitest + Playwright setup ✅ NestJS backends have Jest configured

Gaps

❌ No shared test utilities across projects ❌ No coverage thresholds enforced ❌ No CI/CD test automation ❌ No shared package tests ❌ No E2E testing for mobile apps

2. Shared Test Configuration (packages/test-config/)

Created reusable test configurations for all app types:

packages/test-config/
├── jest.config.backend.js      # NestJS backends
├── jest.config.mobile.js       # React Native mobile
├── vitest.config.base.ts       # Shared packages
├── vitest.config.svelte.ts     # SvelteKit web
├── playwright.config.base.ts   # E2E tests
├── package.json
├── tsconfig.json
└── README.md

Features:

• 80% coverage thresholds enforced
• Auto-clear mocks between tests
• Platform-specific ignore patterns
• Coverage reporting configured
• TypeScript support

3. Example Test Files (docs/test-examples/)

Created comprehensive examples for each app type:

test-examples/
├── backend/
│   ├── example.controller.spec.ts    # Controller testing
│   └── example.service.spec.ts       # Service testing
├── mobile/
│   ├── ExampleComponent.test.tsx     # Component testing
│   └── authService.test.ts           # Service testing
├── web/
│   ├── Button.test.ts                # Svelte 5 components
│   └── page.server.test.ts           # Server functions

│   └── format.test.ts                # Utility functions
└── README.md

Total Example Code: ~3,500 lines of production-quality test examples

4. CI/CD Integration (.github/workflows/)

test.yml

Automated testing workflow with:

• Parallel test execution across all projects
• Coverage reporting to Codecov
• Automated PR comments with results
• 8 job types:
  1. Backend tests (5 projects)
  2. Mobile tests (7 projects)
  3. Web tests (9 projects)
  4. E2E tests (web)
  5. Shared package tests
  6. Lint & format checks
  7. Coverage aggregation
  8. Status reporting

Features:

• Matrix strategy for parallel execution
• Automatic coverage uploads
• PR status checks
• Failure notifications
• Codecov integration

Coverage Strategy

Global Thresholds

• Default: 80% (lines, functions, branches, statements)
• Critical Paths: 100% (auth, payments, data integrity)
• New Code: Must meet 80% minimum
• Pull Requests: Cannot decrease overall coverage

Critical Paths Requiring 100% Coverage

1. Authentication:

   • @manacore/shared-auth package
   • Token management and JWT verification
   • All auth services across apps

2. Payment/Credit System:

   • Credit consumption logic
   • Stripe integration
   • Transaction recording

3. Data Integrity:

   • Database migrations
   • RLS policy validation
   • User data validation

Coverage Reporting

• Local: HTML reports in coverage/ directory
• CI/CD: Uploaded to Codecov
• PR Comments: Coverage diff displayed
• Badges: Available for README files

Testing Best Practices

1. AAA Pattern

it('should create item successfully', async () => {
	// Arrange
	const input = { title: 'Test' };

	// Act
	const result = await service.create(input);

	// Assert
	expect(result).toBeDefined();
});

2. Descriptive Test Names

// ✅ Good
it('should reject sign in with invalid email format');

// ❌ Bad
it('test sign in');

3. Test Behavior, Not Implementation

// ✅ Good - Testing user-facing behavior
expect(screen.getByText('Error message')).toBeVisible();

// ❌ Bad - Testing internal state
expect(component.state.hasError).toBe(true);

4. Mock External Dependencies

// Mock API calls
global.fetch = jest.fn();

// Mock database
jest.mock('@/lib/db');

// Mock storage
jest.mock('expo-secure-store');

5. Clean Up After Tests

beforeEach(() => {
	jest.clearAllMocks();
});

afterEach(() => {
	cleanup();
});
