Antigravity Agent 9a135bd19d docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치.
콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서
전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한
업데이트0615/무제 3.canvas 뿐).

title

Continuous Integration (CI)

매 한 줄

"매 push마다 build + test, fast feedback". Grady Booch (1991) 가 제안, Martin Fowler 가 대중화. 2026 현재 GitHub Actions / GitLab CI 가 표준이며, AI-assisted PR review (Claude Opus 4.7) 와 결합되어 매 commit 검증 cycle 이 분 단위로 압축됨.

매 핵심

매 원칙

Mainline integration 빈번: 매 developer 매일 main 에 merge.
Automated build: 매 commit trigger build pipeline.
Automated test: unit + integration + lint 매 자동 실행.
Fast feedback: <10 min 안에 결과. 길어지면 dev 매 ignore.
Single source of truth: 매 single repo, single mainline.

매 stages

Lint (10s) — eslint, ruff, gofmt.
Unit test (1-3 min) — vitest, pytest, go test.
Integration test (3-8 min) — testcontainers, ephemeral DB.
Build artifact (1-2 min) — docker image, npm tarball.
Static analysis (parallel) — SonarQube, Snyk, CodeQL.

매 응용

SaaS product 매 trunk-based development.
Open-source project 매 PR validation.
Monorepo 매 affected-only build (Turborepo, Nx).

💻 패턴

Modern GitHub Actions (2026)

name: CI
on:
  push: { branches: [main] }
  pull_request:
  merge_group:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

jobs:
  test:
    runs-on: ubuntu-24.04
    steps:
      - uses: actions/checkout@v5
      - uses: actions/setup-node@v5
        with: { node-version: '22', cache: 'pnpm' }
      - run: pnpm install --frozen-lockfile
      - run: pnpm lint
      - run: pnpm test --coverage
      - uses: codecov/codecov-action@v5

Matrix build

strategy:
  fail-fast: false
  matrix:
    os: [ubuntu-24.04, macos-14, windows-2022]
    node: [20, 22]
runs-on: ${{ matrix.os }}

Affected-only (monorepo)

- run: pnpm exec turbo run test --filter=...[origin/main]

Reusable workflow

# .github/workflows/reusable-test.yml
on:
  workflow_call:
    inputs:
      node-version: { type: string, default: '22' }
jobs:
  test:
    runs-on: ubuntu-24.04
    steps: [ ... ]

Container-based test (testcontainers)

# pytest with ephemeral postgres
from testcontainers.postgres import PostgresContainer

def test_repo():
    with PostgresContainer("postgres:17") as pg:
        url = pg.get_connection_url()
        # run integration test against real DB

Cache layers (docker buildx)

- uses: docker/build-push-action@v6
  with:
    context: .
    cache-from: type=gha
    cache-to: type=gha,mode=max
    tags: ghcr.io/org/app:${{ github.sha }}

AI PR review (2026)

- uses: anthropic-experimental/claude-code-action@v1
  with:
    api-key: ${{ secrets.ANTHROPIC_API_KEY }}
    model: claude-opus-4-7
    review-mode: pr-comment

매 결정 기준

상황	Approach
Open-source GitHub repo	GitHub Actions
Self-hosted, private	GitLab CI / Drone
Monorepo	Turborepo + affected-only
Polyglot, complex	Buildkite / Bazel
Mobile (iOS/Android)	Bitrise / Xcode Cloud

기본값: GitHub Actions + concurrency cancel + matrix + cache.

🤖 LLM 활용

언제: PR diff review, flaky test detection, commit message generation, changelog 생성. 언제 X: secret-handling pipeline (보안), production deploy gate (deterministic 해야 함).

❌ 안티패턴

Slow pipeline (>20 min): dev 매 ignore, "broken main" 정상화.
Flaky test 방치: trust collapse → 매 retry, retry, retry.
No mainline protection: 직접 push to main, PR 없음.
Build on developer machine only: "works on my machine" 재현.
Secrets in logs: env 출력, token leak.

🧪 검증 / 중복

Verified (Fowler 2006 Continuous Integration article, GitHub Actions docs 2026).
신뢰도 A.
