# Testing

### Unit Tests
Run unit tests via Karma:
```bash
npm test
```

Tests are written using Jasmine and located alongside components:
- `*.spec.ts` files

### End-to-End Tests
Run e2e tests via Protractor:
```bash
npm run e2e
```

E2E tests are located in the `e2e/` directory.

### Test Configuration
- **Karma**: `karma.conf.js`
- **Protractor**: `e2e/protractor.conf.js`
- **TypeScript**: `tsconfig.spec.json`

### Writing Tests
Example component test:
```typescript
describe('CartComponent', () => {
  let component: CartComponent;
  let fixture: ComponentFixture<CartComponent>;

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [ CartComponent ]
    }).compileComponents();
  });

  beforeEach(() => {
    fixture = TestBed.createComponent(CartComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });

  it('should load cart items', () => {
    component.loadCart();
    expect(component.cartItems.length).toBeGreaterThan(0);
  });
});
```
