refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게 [공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류. 문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인). - Topic_Programming → Domain_Programming (내부 구조 보존) - Topic_Graphic → Domain_Design - Topic_Business → Domain_Product - Topic_General → Domain_General - _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning), Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing) - 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서) - 빈 폴더 정리 (memory/procedures) - 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Quality Control
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 quality 의 inspect 보다 build-in"**. 매 modern QC 의 shift-left — 매 unit test, type checking, static analysis, contract test, e2e — 매 layer 의 different bug class catch. 2026 의 LLM-augmented test generation + property-based testing 의 mainstream.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 Test pyramid (2026 update)
|
||||
- **Unit (60-70%)**: pure function, fast, isolated.
|
||||
- **Integration (15-25%)**: module + DB/queue, real dependencies via testcontainers.
|
||||
- **E2E (5-10%)**: full user journey, Playwright/Cypress.
|
||||
- **Contract (5%)**: Pact, consumer-driven, prevent break-on-deploy.
|
||||
- **Property-based (cross-cutting)**: Hypothesis/fast-check, find edge cases.
|
||||
|
||||
### 매 Quality gates
|
||||
- 매 PR 의 merge 전: lint, type, unit test, coverage threshold, security scan.
|
||||
- 매 deploy 전: integration test, smoke test, canary metrics.
|
||||
- 매 prod: synthetic monitoring, real-user monitoring (RUM).
|
||||
|
||||
### 매 Defect classes
|
||||
- **Functional**: wrong output for given input.
|
||||
- **Performance**: slow, regression on benchmark.
|
||||
- **Security**: OWASP categories.
|
||||
- **Accessibility**: WCAG violations.
|
||||
- **Compatibility**: browser/OS specific.
|
||||
|
||||
### 매 응용
|
||||
1. CI/CD pipeline gates.
|
||||
2. Pre-merge bots (Danger, Reviewdog).
|
||||
3. Mutation testing (Stryker) — quality of tests themselves.
|
||||
4. Visual regression (Chromatic, Percy).
|
||||
5. Chaos engineering (production resilience).
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### Property-based testing (TypeScript with fast-check)
|
||||
```typescript
|
||||
import fc from 'fast-check';
|
||||
import { reverse } from './lib';
|
||||
|
||||
test('reverse twice = identity', () => {
|
||||
fc.assert(
|
||||
fc.property(fc.array(fc.integer()), (arr) => {
|
||||
expect(reverse(reverse(arr))).toEqual(arr);
|
||||
}),
|
||||
);
|
||||
});
|
||||
```
|
||||
|
||||
### Contract test (Pact)
|
||||
```typescript
|
||||
// Consumer side
|
||||
const provider = new Pact({ consumer: 'Web', provider: 'OrdersAPI' });
|
||||
|
||||
await provider.addInteraction({
|
||||
state: 'order 123 exists',
|
||||
uponReceiving: 'a request for order 123',
|
||||
withRequest: { method: 'GET', path: '/orders/123' },
|
||||
willRespondWith: {
|
||||
status: 200,
|
||||
body: { id: '123', total: 99.0 },
|
||||
},
|
||||
});
|
||||
|
||||
// Generates pact.json — provider verifies against it in CI
|
||||
```
|
||||
|
||||
### Mutation testing (Stryker)
|
||||
```javascript
|
||||
// stryker.conf.js
|
||||
export default {
|
||||
testRunner: 'vitest',
|
||||
mutate: ['src/**/*.ts'],
|
||||
thresholds: { high: 80, low: 60, break: 50 },
|
||||
};
|
||||
// Mutates code (a + b → a - b) and checks if tests catch it
|
||||
// Surviving mutants = weak tests
|
||||
```
|
||||
|
||||
### LLM-assisted test generation (2026 pattern)
|
||||
```typescript
|
||||
// CI step: claude-code generates edge cases
|
||||
// $ claude test-gen src/parser.ts --output tests/parser.gen.test.ts
|
||||
// Then human review before merge — never blind-trust
|
||||
```
|
||||
|
||||
### Visual regression (Playwright)
|
||||
```typescript
|
||||
test('homepage matches snapshot', async ({ page }) => {
|
||||
await page.goto('/');
|
||||
await page.waitForLoadState('networkidle');
|
||||
expect(await page.screenshot()).toMatchSnapshot('home.png', {
|
||||
maxDiffPixelRatio: 0.01,
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Coverage gates (vitest)
|
||||
```typescript
|
||||
// vitest.config.ts
|
||||
export default {
|
||||
test: {
|
||||
coverage: {
|
||||
provider: 'v8',
|
||||
thresholds: {
|
||||
lines: 80,
|
||||
functions: 80,
|
||||
branches: 75,
|
||||
statements: 80,
|
||||
},
|
||||
},
|
||||
},
|
||||
};
|
||||
```
|
||||
|
||||
### Pre-commit hook (lint-staged + husky)
|
||||
```json
|
||||
{
|
||||
"lint-staged": {
|
||||
"*.{ts,tsx}": [
|
||||
"eslint --fix",
|
||||
"prettier --write",
|
||||
"vitest related --run"
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Chaos test (Toxiproxy / Litmus)
|
||||
```yaml
|
||||
# Inject 500ms latency into Redis dependency
|
||||
apiVersion: chaos-mesh.org/v1alpha1
|
||||
kind: NetworkChaos
|
||||
spec:
|
||||
action: delay
|
||||
selector:
|
||||
labelSelectors: { app: redis }
|
||||
delay: { latency: 500ms }
|
||||
duration: 60s
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| Pure logic | Unit + property-based |
|
||||
| Multi-service flow | Integration + contract |
|
||||
| User journey | E2E (sparingly) |
|
||||
| Performance regression | Benchmark in CI |
|
||||
| Visual UI | Snapshot + Chromatic |
|
||||
| Test confidence | Mutation score |
|
||||
|
||||
**기본값**: 80% line coverage, mutation score >70%, property-based for parsers/serializers.

|

|
||||
## 🤖 LLM 활용
|
||||
**언제**: generate edge cases, suggest mutation-resistant assertions, identify untested branches.
|
||||
**언제 X**: never let LLM write the assertion AND implementation — confirmation bias.
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **Coverage worship**: 100% coverage, 0% assertions ("test executes but checks nothing").
|
||||
- **Flaky tests ignored**: erodes trust in suite. Quarantine and fix immediately.
|
||||
- **E2E-heavy pyramid**: slow, flaky, expensive. Push down to integration/unit.
|
||||
- **Manual QA only**: doesn't scale, regression-prone.
|
||||
- **No mutation testing**: blind to assertion quality.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (Google Testing Blog, Mike Cohn pyramid, Stryker docs).
|
||||
- 신뢰도 A.
