如何用脚本快速搭建测试环境

  1. Docker Compose 方案（推荐）
  2. Python 自动化脚本
  3. Shell 一键脚本
  4. Ansible Playbook（大项目）
  5. 快速使用建议

我来介绍几种快速搭建测试环境的方法,包括脚本方案和最佳实践。

Docker Compose 方案（推荐）

# docker-compose.yml
version: '3.8'
services:
  # 数据库
  mysql:
    image: mysql:8.0
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_DATABASE: testdb
    ports:
      - "3306:3306"
    volumes:
      - ./sql/init.sql:/docker-entrypoint-initdb.d/init.sql
  redis:
    image: redis:6-alpine
    ports:
      - "6379:6379"
  # 消息队列
  rabbitmq:
    image: rabbitmq:3-management
    environment:
      RABBITMQ_DEFAULT_USER: admin
      RABBITMQ_DEFAULT_PASS: admin123
    ports:
      - "5672:5672"
      - "15672:15672"
  # API 服务
  app:
    build: .
    ports:
      - "8080:8080"
    environment:
      DB_HOST: mysql
      REDIS_HOST: redis
      RABBITMQ_HOST: rabbitmq
    depends_on:
      - mysql
      - redis
      - rabbitmq

启动脚本：

#!/bin/bash
# setup_test_env.sh
echo "🔄 启动测试环境..."
docker-compose up -d
echo "⏳ 等待服务就绪..."
sleep 10
echo "✅ 测试环境就绪！"
echo "MySQL: localhost:3306"
echo "Redis: localhost:6379"
echo "RabbitMQ: localhost:5672"
echo "APP: http://localhost:8080"

Python 自动化脚本

快速使用建议

最小化启动脚本

#!/bin/bash
# 最简测试环境启动
# 1. 启动数据库
docker run -d --name test-db -p 3306:3306 \
  -e MYSQL_ROOT_PASSWORD=root mysql:8.0
# 2. 启动缓存
docker run -d --name test-cache -p 6379:6379 redis:alpine
# 3. 等待就绪
sleep 10 && echo "Ready!"

环境检查工具

import requests
import sys
def check_environment():
    checks = {
        "Database": ("mysql://localhost:3306", "3306"),
        "Redis": ("redis://localhost:6379", "6379"),
        "API": ("http://localhost:8080/health", "8080")
    }
    all_passed = True
    for service, (url, port) in checks.items():
        try:
            if "http" in url:
                r = requests.get(url, timeout=5)
                status = "✅" if r.status_code == 200 else "❌"
            else:
                import socket
                s = socket.socket()
                s.settimeout(2)
                s.connect(('localhost', int(port)))
                status = "✅"
                s.close()
            print(f"{status} {service}: {url}")
        except:
            print(f"❌ {service}: {url} - 不可访问")
            all_passed = False
    return all_passed
if __name__ == "__main__":
    if not check_environment():
        sys.exit(1)
  1. 使用 Docker Compose：最快捷的方式，适合大多数场景
  2. 配置模板化：使用环境变量和配置文件
  3. 健康检查：确保服务真正就绪后再使用
  4. 数据持久化：测试数据可以重复使用
  5. 网络隔离：使用 Docker 网络隔离服务
  6. 日志记录：保留日志便于调试
  7. 清理机制：提供清理脚本释放资源

选择哪种方案取决于你的具体需求,但 Docker Compose + 脚本的方式通常是最实用的组合。
