+# 测试
+
+百思不如一试，测试是发现问题的最佳方式。
+
+不同的用户会有不同的配置，为了提高项目的兼容性，我们需要在不同数据库后端上测试。
+手动进行大量的、重复的测试不可靠，也不现实，因此我们推荐使用 [GitHub Actions](https://github.com/features/actions) 进行自动化测试：
+
+```yaml title=.github/workflows/test.yml {12-42,52-53} showLineNumbers
+name: Test
+
+on:
+  push:
+    branches:
+      - main
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+
+    strategy:
+      matrix:
+        db:
+          - sqlite+aiosqlite:///db.sqlite3
+          - postgresql+psycopg://postgres:postgres@localhost:5432/postgres
+          - mysql+aiomysql://mysql:mysql@localhost:3306/mymysql
+
+      fail-fast: false
+
+    env:
+      SQLALCHEMY_DATABASE_URL: ${{ matrix.db }}
+
+    services:
+      postgresql:
+        image: ${{ startsWith(matrix.db, 'postgresql') && 'postgres' || '' }}
+        env:
+          POSTGRES_USER: postgres
+          POSTGRES_PASSWORD: postgres
+          POSTGRES_DB: postgres
+        ports:
+          - 5432:5432
+
+      mysql:
+        image: ${{ startsWith(matrix.db, 'mysql') && 'mysql' || '' }}
+        env:
+          MYSQL_ROOT_PASSWORD: mysql
+          MYSQL_USER: mysql
+          MYSQL_PASSWORD: mysql
+          MYSQL_DATABASE: mymysql
+        ports:
+          - 3306:3306
+
+    steps:
+      - uses: actions/checkout@v4
+
+      - uses: actions/setup-python@v5
+
+      - name: Install dependencies
+        run: pip install -r requirements.txt
+
+      - name: Run migrations
+        run: pipx run nb-cli orm upgrade
+
+      - name: Run tests
+        run: pytest
+```
+
+如果项目还需要考虑跨平台和跨 Python 版本兼容，测试矩阵中还需要增加这两个维度。
+但是，我们没必要在所有平台和 Python 版本上运行所有数据库的测试，因为很显然，PostgreSQL 和 MySQL 这类独立的数据库后端不会受平台和 Python 影响，而且 Github Actions 的非 Linux 平台不支持运行独立服务：
+
+|             | Python 3.9 | Python 3.10 | Python 3.11 | Python 3.12                 |
+| ----------- | ---------- | ----------- | ----------- | --------------------------- |
+| **Linux**   | SQLite     | SQLite      | SQLite      | SQLite / PostgreSQL / MySQL |
+| **Windows** | SQLite     | SQLite      | SQLite      | SQLite                      |
+| **macOS**   | SQLite     | SQLite      | SQLite      | SQLite                      |
