初回実行時のメッセージ

INFO[0000] Using docker host 'unix:///var/run/docker.sock', and daemon socket 'unix:///var/run/docker.sock' 
WARN  ⚠ You are using Apple M-series chip and you have not specified container architecture, you might encounter issues while running act. If so, try running it with '--container-architecture linux/amd64'. ⚠  
? Please choose the default image you want to use with act:
  - Large size image: ca. 17GB download + 53.1GB storage, you will need 75GB of free disk space, snapshots of GitHub Hosted Runners without snap and pulled docker images
  - Medium size image: ~500MB, includes only necessary tools to bootstrap actions and aims to be compatible with most actions
  - Micro size image: <200MB, contains only NodeJS required to bootstrap actions, doesn't work with all actions

Default image and other options can be changed manually in /Users/sudamasahiro/Library/Application Support/act/actrc (please refer to https://nektosact.com/usage/index.html?highlight=configur#configuration-file for additional information about file structure)  [Use arrows to move, type to filter, ? for more help]

Server Test CI のWorkflow Sample📝

server-ci.yml
# PR が push されたら、テストを実行する。

name: Server CI

on:
  pull_request:
    branches: [main] # レビューゲート
  push:
    branches: [main] # CD 用に拡張可

jobs:
  test:
    name: Run Server-Side Tests
    runs-on: ubuntu-latest # 実行環境（Ubuntu最新版）
    strategy:
      # Node 20.x と Node 22.x の両方でテストを実行する。
      matrix:
        node-version: [20.x, 22.x] # 将来 LTS が増えても1行追加で済む

    # テスト実行のためのステップ
    steps:
      - uses: actions/checkout@v4

      # 1. Node をセットアップ
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}

      # 2. pnpmのセットアップ
      - uses: pnpm/action-setup@v4
        with:
          version: latest

      # 3. 依存インストール & Prisma生成 & テスト（サーバーディレクトリで実行）
      - name: Install dependencies
        working-directory: ./server
        run: pnpm install --frozen-lockfile

      - name: Generate Prisma client
        working-directory: ./server
        run: pnpm prisma generate

      - name: Run tests
        working-directory: ./server
        run: pnpm test -- --ci --reporter=junit

      # 4. テスト結果を GitHub に表示
