TDD와 실제 구현 기반 테스트를 결합한 통합 테스트 스킬입니다.
"NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST"
- 원하는 동작을 보여주는 최소한의 테스트 작성
- 테스트가 실패하는지 반드시 확인
- 테스트를 통과시키는 가장 단순한 코드 작성
- 완벽한 코드 X, 동작하는 코드 O
- 코드 정리 (중복 제거, 명명 개선)
- 테스트가 계속 통과하는지 확인
실제 구현을 테스트하라
jest.mock('./database');
jest.mock('./api');
// 실제 테스트 DB 또는 인메모리 DB 사용
const db = await createTestDatabase();
// MSW로 실제 HTTP 계층 테스트
const server = setupServer(
rest.get('/api/users', (req, res, ctx) => {
return res(ctx.json([{ id: 1, name: 'Test' }]));
})
);
test('user can complete checkout', async ({ page }) => {
await page.goto('/products');
await page.click('[data-testid="add-to-cart"]');
await page.click('[data-testid="checkout"]');
await expect(page.locator('.confirmation')).toBeVisible();
});

development
Apple Human Interface Guidelines for content display components. Use this skill when the user asks about charts component, collection view, image view, web view, color well, image well, activity view, lockup, data visualization, content display, displaying images, rendering web content, color pickers, or presenting collections of items in Apple apps. Also use when the user says how should I display charts, what's the best way to show images, should I use a web view, how do I build a grid of items, what component shows media, or how do I present a share sheet. Cross-references: hig-foundations for color/typography/accessibility, hig-patterns for data visualization patterns, hig-components-layout for structural containers, hig-platforms for platform-specific component behavior.

GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
