## TestHelpers.swift
Proporciona helpers y factories para crear datos de prueba:
### TestDataFactory
Crea objetos de prueba:
```swift
let manga = TestDataFactory.createManga(
slug: "test-manga",
title: "Test Manga"
)
let chapter = TestDataFactory.createChapter(number: 1)
let chapters = TestDataFactory.createChapters(count: 10)
```
### ImageTestHelpers
Crea imágenes de prueba:
```swift
let image = ImageTestHelpers.createTestImage(
color: .blue,
size: CGSize(width: 800, height: 1200)
)
```
### FileSystemTestHelpers
Operaciones de sistema de archivos:
```swift
let tempDir = try FileSystemTestHelpers.createTemporaryDirectory()
try FileSystemTestHelpers.createTestChapterStructure(
mangaSlug: "test",
chapterNumber: 1,
pageCount: 10,
in: tempDir
)
```
### StorageTestHelpers
Limpieza y preparación de almacenamiento:
```swift
StorageTestHelpers.clearAllStorage()
StorageTestHelpers.seedTestData(
favoriteCount: 5,
progressCount: 10
)
```
## Mejores Prácticas
### 1. Independencia de Tests
Cada test debe ser independiente y poder ejecutarse solo:
```swift
override func setUp() {
super.setUp()
// Limpiar estado antes del test
UserDefaults.standard.removeObject(forKey: "favoritesKey")
}
override func tearDown() {
// Limpiar estado después del test
super.tearDown()
}
```
### 2. Nombres Descriptivos
Usa nombres que describan qué se está probando:
```swift
// ✅ Bueno
func testSaveDuplicateFavoriteDoesNotAddDuplicate()
// ❌ Malo
func testFavorite()
```
### 3. Un Assert por Test
Cuando sea posible, usa un assert por test:
```swift
// ✅ Bueno
func testFavoriteIsSaved() {
storageService.saveFavorite(mangaSlug: "test")
XCTAssertTrue(storageService.isFavorite(mangaSlug: "test"))
}
func testFavoriteIsRemoved() {
storageService.saveFavorite(mangaSlug: "test")
storageService.removeFavorite(mangaSlug: "test")
XCTAssertFalse(storageService.isFavorite(mangaSlug: "test"))
}
// ❌ Evitar
func testFavoriteOperations() {
storageService.saveFavorite(mangaSlug: "test")
XCTAssertTrue(storageService.isFavorite(mangaSlug: "test"))
storageService.removeFavorite(mangaSlug: "test")
XCTAssertFalse(storageService.isFavorite(mangaSlug: "test"))
}
```
### 4. AAA Pattern
Usa el patrón Arrange-Act-Assert:
```swift
func testChapterProgressCalculation() {
// Arrange - Preparar el test
var chapter = Chapter(number: 1, title: "Test", url: "", slug: "")
let expectedPage = 5
// Act - Ejecutar la acción
chapter.lastReadPage = expectedPage
// Assert - Verificar el resultado
XCTAssertEqual(chapter.progress, Double(expectedPage))
}
```
### 5. Mock de Dependencias
No hagas llamadas de red reales en tests unitarios:
```swift
// ✅ Bueno - Mock
let mockJSResult = [["number": 10, "title": "Chapter 10"]]
let chapters = parseChaptersFromJS(mockJSResult)
// ❌ Malo - Llamada real
let chapters = await scraper.scrapeChapters(mangaSlug: "test")
```
### 6. Tests Asíncronos
Usa `async/await` apropiadamente:
```swift
func testAsyncImageSave() async throws {
let image = createTestImage()
let url = try await storageService.saveImage(
image,
mangaSlug: "test",
chapterNumber: 1,
pageIndex: 0
)
XCTAssertTrue(FileManager.default.fileExists(atPath: url.path))
}
```
## Cobertura de Código
Objetivos de cobertura:
- **Modelos**: 95%+ (lógica crítica de datos)
- **StorageService**: 90%+ (manejo de archivos y persistencia)
- **Scraper**: 85%+ (con mocks de WKWebView)
- **Integración**: 80%+ (flujos críticos de usuario)
## Troubleshooting
### Tests Fallan Intermittentemente
Si un test falla solo algunas veces:
1. Verifica que hay cleanup adecuado en `tearDown()`
2. Asegura que los tests son independientes
3. Usa `waitFor` apropiadamente para operaciones asíncronas
### Tests de Performance Fallan
Si los tests de rendimiento fallan en diferentes máquinas:
1. Ajusta las métricas según el hardware
2. Usa medidas relativas en lugar de absolutas
3. Considera deshabilitar tests de performance en CI
### Memory Leaks en Tests
Para detectar memory leaks:
```swift
func testNoMemoryLeak() {
let instance = MyClass()
assertNoMemoryLeak(instance)
}
```

- [Unit Testing Best Practices](https://www.objc.io/books/unit-testing/)
## Contribuir
Para agregar nuevos tests:
1. Decide si es unit test, integration test, o performance test
2. Agrega el test al archivo apropiado
3. Usa los helpers en `TestHelpers.swift` cuando sea posible
4. Asegura que el test es independiente
5. Agrega documentación si el test es complejo
6. Ejecuta todos los tests para asegurar que nada se rompe

# Con cobertura
Product > Test > Gather coverage
```
### Con script:
```bash
# Todos los tests
./run_tests.sh --all
# Con cobertura
./run_tests.sh --all --coverage
# Solo unitarios
./run_tests.sh --unit
# Solo integración
./run_tests.sh --integration --verbose
```
### Con xcodebuild:
```bash
xcodebuild test -scheme MangaReader \
-destination 'platform=iOS Simulator,name=iPhone 15'
```
## Próximos Pasos
1. **Ejecutar los tests** para verificar que funcionan
2. **Agregar al proyecto Xcode** como target de tests
3. **Configurar CI/CD** para ejecutar tests automáticamente
4. **Ajustar cobertura** según necesidades
5. **Agregar tests adicionales** para nuevas features
## Notas
- Todos los tests usan XCTest framework
- Compatible con iOS 15+
- Requiere Xcode 14+
- Tests marcados con @MainActor donde es necesario
- Soporte completo para async/await

✅ BUENOS HÁBITOS:
1. Usa nombres descriptivos:
- testSaveFavorite_AddsNewFavorite_WhenNotExists
- testChapterProgress_ReturnsDouble_WhenSet
2. Un assert por test:
- Separa en múltiples tests si hay varios asserts
- Usa subtests si están relacionados
3. Arrange-Act-Assert:
- Arrange: Prepara los datos
- Act: Ejecuta la acción
- Assert: Verifica el resultado
4. Tests independientes:
- No dependen del orden de ejecución
- Limpian después de sí mismos
5. Usa helpers:
- TestDataFactory para crear objetos
- AssertionHelpers para verificar condiciones
❌ MALOS HÁBITOS:
1. Tests con múltiples asserts no relacionados
2. Tests que dependen del orden
3. Tests que no limpian después
4. Tests con nombres ambiguos
5. Tests que llaman a APIs reales
*/
// MARK: - Referencias Rápidas
/*
COMUNES ASSERTIONS:
- XCTAssertEqual(a, b) - Verifica igualdad
- XCTAssertNotEqual(a, b) - Verifica desigualdad
- XCTAssertTrue(condición) - Verifica true
- XCTAssertFalse(condición) - Verifica false
- XCTAssertNil(valor) - Verifica nil
- XCTAssertNotNil(valor) - Verifica no nil
- XCTAssertThrowsError(expr) - Verifica que lanza error
- XCTAssertNoThrow(expr) - Verifica que NO lanza error
ASYNC/AWAIT:
- try await [función async] - Ejecutar función async
- try await Task.sleep(...) - Esperar
- await withTaskGroup {} - Tareas concurrentes
SETUP/TEARDOWN:
- override func setUp() - Antes de cada test
- override func tearDown() - Después de cada test
- override func setUpWithError() - Con errores
- override func tearDownWithError() - Con errores
PERFORMANCE:
- measure { } - Medir bloques de código
- measure(metrics: ...) { } - Métricas específicas
MOCKS:
- TestDataFactory - Crear objetos de prueba
- ImageTestHelpers - Crear imágenes
- FileSystemTestHelpers - Operaciones de archivos

Guía de Ejecución de Tests:
1. Ejecutar todos los tests:
- Cmd + U en Xcode
- O seleccionar Product > Test
2. Ejecutar tests específicos:
- Click derecho en el test específico > Run
- Usar el Test Navigator (Cmd + 6)
3. Ejecutar tests con cobertura:
- Edit Scheme > Test > Options > Gather coverage
- Cmd + U
4. Tests Performance:
- Los tests de performance se marcan con "measure"
- Se ejecutan 10 veces por defecto
- Resultados en el Report Navigator
Estructura de Tests:
- ModelTests: Pruebas para modelos de datos (Manga, Chapter, etc.)
- StorageServiceTests: Pruebas para almacenamiento local
- ManhwaWebScraperTests: Pruebas para el web scraper
- IntegrationTests: Pruebas de integración completa
Mejores Prácticas:
1. Cada test debe ser independiente
2. Los tests deben poder ejecutarse en cualquier orden
3. Usar setUp/tearDown para limpieza
4. Usar nombres descriptivos para los tests
5. Un assert por test (cuando sea posible)
6. Mock de dependencias externas
7. Evitar llamadas de red reales en tests unitarios
Marcas de Tests:
- @MainActor: Tests que requieren MainActor
- async: Tests asíncronos
- throws: Tests que pueden lanzar errores
