ORIGIN_TESTING_STRATEGY.md

📋 RÉSUMÉ EXÉCUTIF

Ce document définit la stratégie de testing complète et définitive pour la plateforme Veza. Il couvre tous les types de tests (unit, integration, E2E, performance, security, load) avec couverture minimale 80%, outils standardisés, processus CI/CD automatisé, et méthodologies (TDD, BDD). Cette stratégie garantit qualité production, réduction bugs, et confiance déploiement continu sur 24 mois.

🎯 OBJECTIFS

Objectif Principal

Établir une culture de testing exhaustive avec couverture ≥ 80%, automatisation complète CI/CD, et détection précoce de régressions pour assurer déploiements production sans risque et maintenance long-terme facilitée.

Objectifs Secondaires

  • Réduire taux de bugs en production (< 0.1% des releases)
  • Accélérer feedback loop (tests < 10 min en CI/CD)
  • Faciliter refactoring avec confiance (tests comme safety net)
  • Documenter comportement attendu via tests
  • Détecter problèmes performance avant production

🔒 RÈGLES IMMUABLES

  1. Coverage Minimum: 80% line coverage pour nouveau code - CI/CD bloque si < 80%
  2. Test Before Merge: Aucun PR mergé sans tests - aucune exception
  3. Test Isolation: Chaque test indépendant (no shared state, no order dependency)
  4. Fast Feedback: Tests unitaires < 2 min, integration < 5 min, E2E < 10 min
  5. Deterministic: Tests 100% reproductibles (no flaky tests tolérés)
  6. Test Data: Fixtures isolées, cleanup automatique (no test pollution)
  7. Mocking: Dependencies externes mockées (DB, APIs, time)
  8. Regression: Bug fix = nouveau test (prevent recurrence)
  9. Documentation: Tests servent de documentation (readable, self-explanatory)
  10. Performance: Tests de performance en CI/CD (regression detection)

1. TESTING PHILOSOPHY

1.1 Testing Pyramid

         ╱╲
         E2E ╲                  10% - Slow, Brittle, High Cost
      ╱────────╲
      Integration ╲             20% - Medium Speed, Medium Cost
   ╱──────────────╲
     Unit Tests     ╲           70% - Fast, Reliable, Low Cost
╱────────────────────╲

Distribution:

  • Unit Tests (70%): Fast, isolated, test single functions/methods
  • Integration Tests (20%): Medium speed, test component interactions
  • E2E Tests (10%): Slow, test complete user flows

1.2 Testing Principles

F.I.R.S.T Principles:

  • Fast: Tests execute quickly (unit < 100ms, all tests < 10min)
  • Independent: No test depends on another (can run in any order)
  • Repeatable: Same result every time (deterministic)
  • Self-Validating: Pass/fail clear (no manual inspection)
  • Timely: Written with code (not after, preferably before - TDD)

Test Qualities:

  • Readable: Anyone can understand what's being tested
  • Maintainable: Easy to update when requirements change
  • Trustworthy: No false positives/negatives (no flaky tests)
  • Comprehensive: Cover happy path + edge cases + error cases

1.3 TDD (Test-Driven Development)

Red-Green-Refactor Cycle:

1. 🔴 RED: Write failing test first
2. 🟢 GREEN: Write minimum code to pass
3. 🔵 REFACTOR: Clean up code while tests pass
4. Repeat

Example Flow:

// 1. RED - Write failing test
func TestCreateUser_Success(t *testing.T) {
    service := NewUserService()
    user := &User{Email: "test@example.com"}
    
    err := service.CreateUser(user)
    assert.NoError(t, err)
    assert.NotEmpty(t, user.ID)
}
// Test fails - CreateUser doesn't exist yet

// 2. GREEN - Implement minimum code
func (s *UserService) CreateUser(user *User) error {
    user.ID = uuid.New().String()
    return nil
}
// Test passes

// 3. REFACTOR - Improve code
func (s *UserService) CreateUser(user *User) error {
    if err := validateEmail(user.Email); err != nil {
        return err
    }
    user.ID = uuid.New().String()
    return s.repo.Save(user)
}
// Tests still pass

2. TEST TYPES & COVERAGE

2.1 Coverage Requirements

Test Type Coverage Target Execution Time Frequency
Unit Tests ≥ 80% line coverage < 2 min Every commit
Integration Tests ≥ 70% API endpoints < 5 min Every commit
E2E Tests ≥ 50% critical flows < 10 min Every commit (smoke), Full nightly
Performance Tests 100% critical endpoints < 15 min Nightly + Pre-release
Security Tests 100% OWASP Top 10 < 20 min Weekly + Pre-release
Load Tests 100% production scenarios 30-60 min Weekly + Pre-release

2.2 Coverage Metrics

Tracked Metrics:

  • Line Coverage: % of lines executed during tests
  • Branch Coverage: % of conditional branches tested
  • Function Coverage: % of functions called
  • Statement Coverage: % of statements executed

Tools:

  • Go: go test -cover, gocov
  • Rust: cargo tarpaulin
  • TypeScript: vitest --coverage (c8)

Example Coverage Report:

# Go
go test ./... -coverprofile=coverage.out
go tool cover -html=coverage.out -o coverage.html

# Coverage output:
# internal/services/user_service.go:     CreateUser           85.7%
# internal/services/track_service.go:    UploadTrack          92.3%
# internal/handlers/auth_handlers.go:    Login                78.5%  ⚠️ Below 80%

3. UNIT TESTING

3.1 Unit Test Structure (AAA Pattern)

Arrange-Act-Assert:

func TestUserService_CreateUser_Success(t *testing.T) {
    // ARRANGE - Setup test data and dependencies
    mockRepo := &MockUserRepository{}
    mockRepo.CreateFunc = func(user *User) error {
        return nil
    }
    service := NewUserService(mockRepo)
    user := &User{
        Email:    "test@example.com",
        Username: "testuser",
    }
    
    // ACT - Execute the function under test
    err := service.CreateUser(user)
    
    // ASSERT - Verify the outcome
    assert.NoError(t, err)
    assert.NotEmpty(t, user.ID)
    assert.NotEmpty(t, user.CreatedAt)
}

3.2 Test Naming Convention

Format: Test<FunctionName>_<Scenario>_<ExpectedBehavior>

Examples:

// ✅ GOOD - Descriptive test names
func TestCreateUser_ValidData_Success(t *testing.T) { }
func TestCreateUser_DuplicateEmail_ReturnsConflictError(t *testing.T) { }
func TestCreateUser_InvalidEmail_ReturnsValidationError(t *testing.T) { }
func TestGetUserByID_ExistingUser_ReturnsUser(t *testing.T) { }
func TestGetUserByID_NonExistentUser_ReturnsNotFoundError(t *testing.T) { }

// ❌ BAD - Unclear test names
func TestCreateUser(t *testing.T) { }
func TestUser(t *testing.T) { }
func TestSuccess(t *testing.T) { }

3.3 Table-Driven Tests

func TestValidateEmail(t *testing.T) {
    tests := []struct {
        name    string
        email   string
        wantErr bool
        errMsg  string
    }{
        {
            name:    "valid email",
            email:   "user@example.com",
            wantErr: false,
        },
        {
            name:    "valid email with subdomain",
            email:   "user@mail.example.com",
            wantErr: false,
        },
        {
            name:    "missing @ symbol",
            email:   "userexample.com",
            wantErr: true,
            errMsg:  "invalid email format",
        },
        {
            name:    "missing domain",
            email:   "user@",
            wantErr: true,
            errMsg:  "invalid email format",
        },
        {
            name:    "empty string",
            email:   "",
            wantErr: true,
            errMsg:  "email is required",
        },
    }
    
    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            err := validateEmail(tt.email)
            
            if tt.wantErr {
                assert.Error(t, err)
                if tt.errMsg != "" {
                    assert.Contains(t, err.Error(), tt.errMsg)
                }
            } else {
                assert.NoError(t, err)
            }
        })
    }
}

3.4 Mocking (Go)

Interface-Based Mocking:

// Production interface
type UserRepository interface {
    Create(user *User) error
    GetByID(id string) (*User, error)
    GetByEmail(email string) (*User, error)
    Update(user *User) error
    Delete(id string) error
}

// Mock implementation
type MockUserRepository struct {
    CreateFunc    func(user *User) error
    GetByIDFunc   func(id string) (*User, error)
    GetByEmailFunc func(email string) (*User, error)
    UpdateFunc    func(user *User) error
    DeleteFunc    func(id string) error
}

func (m *MockUserRepository) Create(user *User) error {
    if m.CreateFunc != nil {
        return m.CreateFunc(user)
    }
    return nil
}

func (m *MockUserRepository) GetByID(id string) (*User, error) {
    if m.GetByIDFunc != nil {
        return m.GetByIDFunc(id)
    }
    return nil, errors.New("not implemented")
}

// Test usage
func TestUserService_CreateUser(t *testing.T) {
    mockRepo := &MockUserRepository{
        CreateFunc: func(user *User) error {
            user.ID = "mock-id-123"
            return nil
        },
        GetByEmailFunc: func(email string) (*User, error) {
            return nil, gorm.ErrRecordNotFound // Simulate no existing user
        },
    }
    
    service := NewUserService(mockRepo)
    user := &User{Email: "test@example.com"}
    
    err := service.CreateUser(user)
    assert.NoError(t, err)
    assert.Equal(t, "mock-id-123", user.ID)
}

3.5 Testing Async Code (TypeScript)

import { describe, it, expect, vi } from 'vitest';

describe('UserService', () => {
  it('should create user successfully', async () => {
    // ARRANGE
    const mockRepo = {
      create: vi.fn().mockResolvedValue({ id: 'user-123' }),
      getByEmail: vi.fn().mockResolvedValue(null),
    };
    const service = new UserService(mockRepo);
    const user = { email: 'test@example.com', username: 'testuser' };
    
    // ACT
    const result = await service.createUser(user);
    
    // ASSERT
    expect(result).toHaveProperty('id');
    expect(mockRepo.create).toHaveBeenCalledWith(
      expect.objectContaining({ email: 'test@example.com' })
    );
  });
  
  it('should handle errors gracefully', async () => {
    // ARRANGE
    const mockRepo = {
      create: vi.fn().mockRejectedValue(new Error('Database error')),
      getByEmail: vi.fn().mockResolvedValue(null),
    };
    const service = new UserService(mockRepo);
    
    // ACT & ASSERT
    await expect(service.createUser({ email: 'test@example.com' }))
      .rejects
      .toThrow('Database error');
  });
});

4. INTEGRATION TESTING

4.1 API Integration Tests (Go)

Test with Real Database (Testcontainers):

import (
    "testing"
    "github.com/testcontainers/testcontainers-go"
    "github.com/testcontainers/testcontainers-go/wait"
)

func setupTestDB(t *testing.T) *gorm.DB {
    ctx := context.Background()
    
    // Start PostgreSQL container
    req := testcontainers.ContainerRequest{
        Image:        "postgres:15-alpine",
        ExposedPorts: []string{"5432/tcp"},
        Env: map[string]string{
            "POSTGRES_DB":       "test_db",
            "POSTGRES_USER":     "test",
            "POSTGRES_PASSWORD": "test",
        },
        WaitingFor: wait.ForLog("database system is ready to accept connections"),
    }
    
    container, err := testcontainers.GenericContainer(ctx, testcontainers.GenericContainerRequest{
        ContainerRequest: req,
        Started:          true,
    })
    require.NoError(t, err)
    
    t.Cleanup(func() {
        container.Terminate(ctx)
    })
    
    // Get connection string
    host, _ := container.Host(ctx)
    port, _ := container.MappedPort(ctx, "5432")
    dsn := fmt.Sprintf("host=%s port=%s user=test password=test dbname=test_db sslmode=disable", host, port.Port())
    
    // Connect and migrate
    db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
    require.NoError(t, err)
    
    db.AutoMigrate(&User{}, &Track{}, &Playlist{})
    
    return db
}

func TestUserAPI_CreateUser_Integration(t *testing.T) {
    // ARRANGE
    db := setupTestDB(t)
    router := setupRouter(db)
    
    payload := map[string]interface{}{
        "email":    "test@example.com",
        "username": "testuser",
        "password": "SecurePass123!",
    }
    body, _ := json.Marshal(payload)
    
    req := httptest.NewRequest("POST", "/api/v1/users", bytes.NewReader(body))
    req.Header.Set("Content-Type", "application/json")
    w := httptest.NewRecorder()
    
    // ACT
    router.ServeHTTP(w, req)
    
    // ASSERT
    assert.Equal(t, 201, w.Code)
    
    var response map[string]interface{}
    json.Unmarshal(w.Body.Bytes(), &response)
    
    assert.Contains(t, response, "data")
    userData := response["data"].(map[string]interface{})
    assert.Equal(t, "test@example.com", userData["email"])
    assert.NotEmpty(t, userData["id"])
    
    // Verify in database
    var user User
    err := db.First(&user, "email = ?", "test@example.com").Error
    assert.NoError(t, err)
    assert.Equal(t, "testuser", user.Username)
}

4.2 Database Integration Tests (Rust)

Tous les services Rust (chat-server, stream-server) doivent être testés avec une base de données réelle via sqlx::test. Les tests utilisent une base PostgreSQL temporaire créée et détruite automatiquement par le macro #[sqlx::test].

Test CRUD de base :

use sqlx::PgPool;

#[sqlx::test]
async fn test_create_user(pool: PgPool) -> sqlx::Result<()> {
    // ARRANGE
    let user = User {
        id: Uuid::new_v4(),
        email: "test@example.com".to_string(),
        username: "testuser".to_string(),
        password_hash: "hashed_password".to_string(),
    };
    
    // ACT
    let result = sqlx::query!(
        "INSERT INTO users (id, email, username, password_hash) VALUES ($1, $2, $3, $4)",
        user.id,
        user.email,
        user.username,
        user.password_hash
    )
    .execute(&pool)
    .await?;
    
    // ASSERT
    assert_eq!(result.rows_affected(), 1);
    
    let fetched_user = sqlx::query_as!(
        User,
        "SELECT id, email, username, password_hash, created_at FROM users WHERE id = $1",
        user.id
    )
    .fetch_one(&pool)
    .await?;
    
    assert_eq!(fetched_user.email, "test@example.com");
    assert_eq!(fetched_user.username, "testuser");
    
    Ok(())
}

Tests transactionnels et contraintes d'intégrité :

#[sqlx::test]
async fn test_unique_email_constraint(pool: PgPool) -> sqlx::Result<()> {
    let id1 = Uuid::new_v4();
    let id2 = Uuid::new_v4();
    
    sqlx::query!(
        "INSERT INTO users (id, email, username, password_hash) VALUES ($1, $2, $3, $4)",
        id1, "duplicate@example.com", "user1", "hash1"
    )
    .execute(&pool)
    .await?;
    
    let result = sqlx::query!(
        "INSERT INTO users (id, email, username, password_hash) VALUES ($1, $2, $3, $4)",
        id2, "duplicate@example.com", "user2", "hash2"
    )
    .execute(&pool)
    .await;
    
    assert!(result.is_err(), "Duplicate email must be rejected");
    Ok(())
}

#[sqlx::test]
async fn test_cascade_delete_user_tracks(pool: PgPool) -> sqlx::Result<()> {
    let user_id = Uuid::new_v4();
    let track_id = Uuid::new_v4();
    
    sqlx::query!("INSERT INTO users (id, email, username, password_hash) VALUES ($1, $2, $3, $4)",
        user_id, "artist@example.com", "artist", "hash")
        .execute(&pool).await?;
    
    sqlx::query!("INSERT INTO tracks (id, user_id, title, genre, duration_seconds) VALUES ($1, $2, $3, $4, $5)",
        track_id, user_id, "My Song", "electronic", 240)
        .execute(&pool).await?;
    
    sqlx::query!("DELETE FROM users WHERE id = $1", user_id)
        .execute(&pool).await?;
    
    let track = sqlx::query!("SELECT id FROM tracks WHERE id = $1", track_id)
        .fetch_optional(&pool).await?;
    
    assert!(track.is_none(), "Tracks must be cascade-deleted with user");
    Ok(())
}

CI Integration : Les tests Rust avec DB tournent dans le job integration-tests du workflow GitHub Actions, avec un service PostgreSQL dédié (cf. section 10.1).


### 4.3 API Contract Testing

**OpenAPI Schema Validation**:
```typescript
import { describe, it, expect } from 'vitest';
import { validateAgainstSchema } from './openapi-validator';

describe('API Contract Tests', () => {
  it('POST /users response matches OpenAPI schema', async () => {
    const response = await fetch('http://localhost:8080/api/v1/users', {
      method: 'POST',
      body: JSON.stringify({
        email: 'test@example.com',
        username: 'testuser',
        password: 'SecurePass123!',
      }),
      headers: { 'Content-Type': 'application/json' },
    });
    
    const data = await response.json();
    
    // Validate against OpenAPI schema
    const validation = validateAgainstSchema(
      'POST',
      '/users',
      201,
      data
    );
    
    expect(validation.valid).toBe(true);
    expect(validation.errors).toHaveLength(0);
  });
});

5.2 Visual Regression Testing

import { test, expect } from '@playwright/test';

test('homepage visual regression', async ({ page }) => {
  await page.goto('/');
  
  // Take screenshot and compare with baseline
  await expect(page).toHaveScreenshot('homepage.png', {
    fullPage: true,
    maxDiffPixels: 100, // Allow small differences
  });
});

test('user profile visual regression', async ({ page }) => {

8. LOAD & STRESS TESTING

8.1 Load Testing Scenarios

Scenario 1: Normal Load (1000 concurrent users):

// k6-normal-load.js
export const options = {
  vus: 1000,
  duration: '10m',
  thresholds: {
    http_req_duration: ['p(95)<100', 'p(99)<200'],
    http_req_failed: ['rate<0.01'],
  },
};

export default function () {
  // Simulate realistic user behavior
  http.get('https://api.veza.app/v1/tracks');
  sleep(Math.random() * 3 + 2); // 2-5s
  
  http.get('https://api.veza.app/v1/tracks/track-123');
  sleep(Math.random() * 5 + 5); // 5-10s
  
  http.post('https://api.veza.app/v1/tracks/track-123/play');
  sleep(Math.random() * 180 + 60); // 1-4min (listening to track)
}

Scenario 2: Peak Load (5000 concurrent users):

export const options = {
  stages: [
    { duration: '5m', target: 5000 },
    { duration: '10m', target: 5000 },
    { duration: '5m', target: 0 },
  ],
};

Scenario 3: Stress Test (Find breaking point):

export const options = {
  stages: [
    { duration: '2m', target: 1000 },
    { duration: '5m', target: 1000 },
    { duration: '2m', target: 2000 },
    { duration: '5m', target: 2000 },
    { duration: '2m', target: 5000 },
    { duration: '5m', target: 5000 },
    { duration: '2m', target: 10000 }, // Push to breaking point
    { duration: '5m', target: 10000 },
    { duration: '10m', target: 0 },
  ],
};

8.2 Spike Testing

// k6-spike-test.js
export const options = {
  stages: [
    { duration: '1m', target: 100 },    // Normal load
    { duration: '10s', target: 10000 }, // Sudden spike
    { duration: '3m', target: 10000 },  // Stay at spike
    { duration: '10s', target: 100 },   // Drop back
    { duration: '1m', target: 100 },    // Recover
  ],
};

9. TEST DATA MANAGEMENT

9.1 Test Fixtures

Go Test Fixtures:

// testdata/fixtures.go
package testdata

func CreateTestUser() *User {
    return &User{
        ID:       uuid.New().String(),
        Email:    "test@example.com",
        Username: "testuser",
        Role:     "user",
    }
}

func CreateTestTrack() *Track {
    return &Track{
        ID:              uuid.New().String(),
        Title:           "Test Track",
        Artist:          "Test Artist",
        Genre:           "electronic",
        DurationSeconds: 240,
    }
}

TypeScript Fixtures:

// tests/fixtures/users.ts
export const testUsers = {
  normalUser: {
    id: 'user-123',
    email: 'user@example.com',
    username: 'testuser',
    role: 'user',
  },
  premiumUser: {
    id: 'user-456',
    email: 'premium@example.com',
    username: 'premiumuser',
    role: 'premium',
  },
  admin: {
    id: 'user-789',
    email: 'admin@example.com',
    username: 'admin',
    role: 'admin',
  },
};

9.2 Test Database Seeding

-- tests/seed.sql
-- Seed database with test data

INSERT INTO users (id, email, username, password_hash, role)
VALUES 
  ('user-123', 'user@example.com', 'testuser', 'hashed_password', 'user'),
  ('user-456', 'premium@example.com', 'premiumuser', 'hashed_password', 'premium'),
  ('user-789', 'admin@example.com', 'admin', 'hashed_password', 'admin');

INSERT INTO tracks (id, user_id, title, artist, genre, duration_seconds)
VALUES
  ('track-123', 'user-123', 'Test Track 1', 'Test Artist', 'electronic', 240),
  ('track-456', 'user-123', 'Test Track 2', 'Test Artist', 'rock', 180),
  ('track-789', 'user-456', 'Premium Track', 'Premium Artist', 'jazz', 300);

9.3 Cleanup Strategy

func TestMain(m *testing.M) {
    // Setup
    db := setupTestDB()
    
    // Run tests
    code := m.Run()
    
    // Cleanup
    db.Exec("TRUNCATE TABLE users CASCADE")
    db.Exec("TRUNCATE TABLE tracks CASCADE")
    db.Exec("TRUNCATE TABLE playlists CASCADE")
    
    os.Exit(code)
}

func setupTest(t *testing.T, db *gorm.DB) {
    t.Cleanup(func() {
        db.Exec("DELETE FROM users")
        db.Exec("DELETE FROM tracks")
    })

  • Load test passed (5000 concurrent users)
  • E2E tests passed (all critical flows)
  • Security scan passed (OWASP ZAP)
  • Smoke tests passed in staging

13. TESTS POST-DÉPLOIEMENT (SMOKE TESTS)

13.1 Smoke Tests Automatisés

Après chaque déploiement en staging ou production, un ensemble de smoke tests automatisés doit s'exécuter pour valider que les services principaux fonctionnent correctement.

Script de smoke tests :

#!/bin/bash
# scripts/smoke-tests.sh
set -euo pipefail

BASE_URL="${1:-https://api.veza.app}"
FAILURES=0

check() {
  local name="$1" url="$2" expected_status="$3"
  status=$(curl -s -o /dev/null -w "%{http_code}" "$url")
  if [ "$status" != "$expected_status" ]; then
    echo "FAIL: $name — expected $expected_status, got $status"
    FAILURES=$((FAILURES + 1))
  else
    echo "PASS: $name"
  fi
}

check "Health endpoint"       "$BASE_URL/health"          "200"
check "API version"           "$BASE_URL/v1/version"      "200"
check "Tracks listing"        "$BASE_URL/v1/tracks"       "200"
check "Auth (no token)"       "$BASE_URL/v1/me"           "401"
check "Discovery endpoint"    "$BASE_URL/v1/discover"     "200"
check "Stream health"         "$BASE_URL/v1/stream/health" "200"

if [ "$FAILURES" -gt 0 ]; then
  echo "SMOKE TESTS FAILED: $FAILURES failure(s)"
  exit 1
fi
echo "ALL SMOKE TESTS PASSED"

13.2 Intégration CI/CD

Les smoke tests s'exécutent automatiquement :

  • Post-deploy staging : bloquant — échec = rollback automatique
  • Post-deploy production : bloquant — échec = rollback + alerte PagerDuty
# Extrait du workflow deploy-production.yml
- name: Run post-deployment smoke tests
  run: |
    ./scripts/smoke-tests.sh https://api.veza.app    
  timeout-minutes: 5

- name: Rollback on smoke test failure
  if: failure()
  run: |
    kubectl rollout undo deployment/veza-backend -n veza-production
    echo "ROLLBACK TRIGGERED — smoke tests failed"    

13.3 Smoke Tests WebSocket (Chat Server)

import WebSocket from 'ws';

async function smokeTestWebSocket(url: string): Promise<void> {
  return new Promise((resolve, reject) => {
    const ws = new WebSocket(`${url}/ws/health`);
    const timeout = setTimeout(() => {
      ws.close();
      reject(new Error('WebSocket health check timed out'));
    }, 5000);

    ws.on('open', () => {
      clearTimeout(timeout);
      ws.close();
      resolve();
    });

    ws.on('error', (err) => {
      clearTimeout(timeout);
      reject(err);
    });
  });
}

14. TESTS DE L'ALGORITHME DE DÉCOUVERTE

14.1 Objectif

L'algorithme de découverte de Veza est un élément éthique fondamental : il ne doit jamais favoriser les artistes populaires au détriment des artistes émergents. Les tests doivent vérifier cette propriété de manière automatisée.

14.2 Tests de Distribution (Go)

func TestDiscovery_DoesNotFavorPopularArtists(t *testing.T) {
    db := setupTestDB(t)
    
    // Seed : 10 artistes populaires (>10k plays) et 40 artistes émergents (<100 plays)
    for i := 0; i < 10; i++ {
        seedArtist(t, db, fmt.Sprintf("popular-%d", i), 10000+rand.Intn(50000))
    }
    for i := 0; i < 40; i++ {
        seedArtist(t, db, fmt.Sprintf("emerging-%d", i), rand.Intn(100))
    }
    
    service := NewDiscoveryService(db)
    results, err := service.Discover(context.Background(), DiscoveryParams{
        Limit: 20,
    })
    require.NoError(t, err)
    require.Len(t, results, 20)
    
    popularCount := 0
    emergingCount := 0
    for _, track := range results {
        if track.PlayCount > 1000 {
            popularCount++
        } else {
            emergingCount++
        }
    }

14.4 Exécution CI

Les tests de l'algorithme de découverte font partie du job integration-tests et s'exécutent à chaque PR et nightly build. Un échec est bloquant.

15. STRATÉGIE DE TEST ÉTHIQUE

15.1 Principes

Veza refuse l'IA/ML, le Web3/NFT, la gamification addictive, et le tracking publicitaire. Les tests éthiques garantissent ces engagements de manière vérifiable et automatisée.

15.2 Tests de Biais Algorithmique

Tous les algorithmes exposant du contenu (découverte, recherche, suggestions) doivent être testés contre les biais suivants :

Biais Critère Seuil
Popularité Les artistes émergents (<100 plays) doivent apparaître proportionnellement ≥ 50% des résultats
Ancienneté Les nouveaux artistes (<30 jours) doivent apparaître ≥ 20% des résultats
Genre Au moins 3 genres dans chaque page de découverte Minimum 3 genres
Géographie Pas de biais pays (si donnée disponible) Aucun pays > 40%

Ces tests sont exécutés nightly et à chaque PR modifiant les services de découverte ou de recherche.

15.3 Tests d'Accessibilité Automatisés (axe-core)

L'accessibilité est testée automatiquement dans le pipeline CI via @axe-core/playwright :

import { test, expect } from '@playwright/test';
import AxeBuilder from '@axe-core/playwright';

const CRITICAL_PAGES = ['/', '/discover', '/login', '/register', '/upload', '/settings'];

for (const path of CRITICAL_PAGES) {
  test(`accessibility audit: ${path}`, async ({ page }) => {
    await page.goto(path);
    
    const results = await new AxeBuilder({ page })
      .withTags(['wcag2a', 'wcag2aa', 'wcag21aa'])
      .analyze();
    
    expect(results.violations).toEqual([]);
  });
}

test('accessibility: audio player controls', async ({ page }) => {
  await page.goto('/tracks/test-track');
  
  const results = await new AxeBuilder({ page })
    .include('.audio-player')
    .withTags(['wcag2a', 'wcag2aa'])
    .analyze();
  
  expect(results.violations).toEqual([]);
  
  // Keyboard navigation verification
  await page.keyboard.press('Tab');
  const playButton = page.locator('.audio-player button[aria-label="Play"]');
  await expect(playButton).toBeFocused();
});

CI Integration :

# Extrait du workflow test.yml
- name: Run accessibility tests (axe-core)
  run: |
    cd apps/web
    npx playwright test tests/accessibility/ --project=chromium    

Critère bloquant : Zéro violation WCAG 2.1 AA sur les pages critiques. Les violations sont bloquantes en CI.

15.4 Tests de Conformité RGPD

import { test, expect } from '@playwright/test';

test.describe('GDPR Compliance', () => {
  test('user can export all personal data', async ({ request }) => {
    const token = await getAuthToken(request, 'gdpr-test-user@example.com');
    
    const exportResponse = await request.post('/api/v1/me/data-export', {
      headers: { Authorization: `Bearer ${token}` },
    });
    
    expect(exportResponse.status()).toBe(200);
    
    const data = await exportResponse.json();
    expect(data).toHaveProperty('user');
    expect(data).toHaveProperty('tracks');
    expect(data).toHaveProperty('playlists');
    expect(data).toHaveProperty('listening_history');
    expect(data.user.email).toBe('gdpr-test-user@example.com');
  });
  
  test('user can delete account and all associated data', async ({ request }) => {
    const token = await getAuthToken(request, 'delete-test-user@example.com');
    
    // Request deletion
    const deleteResponse = await request.delete('/api/v1/me', {
      headers: { Authorization: `Bearer ${token}` },
    });
    expect(deleteResponse.status()).toBe(200);
    
    // Verify account is gone
    const profileResponse = await request.get('/api/v1/me', {
      headers: { Authorization: `Bearer ${token}` },
    });
    expect(profileResponse.status()).toBe(401);
    
    // Verify associated data is deleted (admin endpoint for test)
    const adminToken = await getAdminToken(request);
    const dataCheck = await request.get('/api/v1/admin/user-data-check/delete-test-user@example.com', {
      headers: { Authorization: `Bearer ${adminToken}` },
    });
    const remaining = await dataCheck.json();
    expect(remaining.tracks).toBe(0);
    expect(remaining.playlists).toBe(0);
    expect(remaining.messages).toBe(0);
  });
  
  test('exported data does not contain other users data', async ({ request }) => {
    const token = await getAuthToken(request, 'gdpr-test-user@example.com');
    
    const exportResponse = await request.post('/api/v1/me/data-export', {
      headers: { Authorization: `Bearer ${token}` },
    });
    const data = await exportResponse.json();
    
    const allEmails = JSON.stringify(data);
    expect(allEmails).not.toContain('other-user@example.com');
    expect(allEmails).not.toContain('admin@example.com');
  });
});

Exécution : Les tests RGPD s'exécutent dans le job E2E, à chaque PR et en nightly build. Un échec est bloquant pour le merge et le déploiement.

15.5 Tests Anti-Tracking

    endpoints := []string{"/v1/tracks", "/v1/discover", "/v1/users/profile"}
    
    for _, endpoint := range endpoints {
        t.Run(endpoint, func(t *testing.T) {
            req := httptest.NewRequest("GET", endpoint, nil)
            w := httptest.NewRecorder()
            router.ServeHTTP(w, req)
            
            // No tracking/fingerprinting headers
            assert.Empty(t, w.Header().Get("X-Request-Fingerprint"))
            assert.Empty(t, w.Header().Get("X-Device-ID"))
            
            // No third-party tracking cookies
            for _, cookie := range w.Result().Cookies() {
                assert.NotContains(t, cookie.Name, "_ga")
                assert.NotContains(t, cookie.Name, "_fbp")
                assert.NotContains(t, cookie.Name, "tracker")
            }
        })
    }
