description	测试与运维技能。当用户需要测试、部署、监控、CI/CD、Docker时自动激活。 触发词：测试、部署、上线、Docker、K8s、CI/CD、监控、GitHub Actions、 自动化测试、E2E、性能测试、安全、运维、服务器、云服务。

测试与运维技能

自动选型规则

场景	推荐方案
单元测试	Vitest + Testing Library
E2E测试	Playwright (首选) / Cypress
API测试	Vitest + Supertest / Postman
CI/CD	GitHub Actions
容器化	Docker + Docker Compose
小团队部署	Vercel(前端) + Railway(后端)
国内部署	阿里云ECS + RDS + OSS
监控	Sentry(错误) + Uptime Kuma(可用性)

测试规范

单元测试模板 (Vitest)

import { describe, it, expect, vi } from 'vitest';
import { userService } from './user.service';

describe('UserService', () => {
  it('should create user with valid data', async () => {
    const data = { phone: '13800138000', nickname: 'Test' };
    const user = await userService.create(data);
    expect(user.phone).toBe(data.phone);
  });

  it('should reject duplicate phone', async () => {
    const data = { phone: '13800138000', nickname: 'Test' };
    await expect(userService.create(data)).rejects.toThrow('已存在');
  });
});

E2E测试模板 (Playwright)

import { test, expect } from '@playwright/test';

test('登录流程', async ({ page }) => {
  await page.goto('/login');
  await page.fill('[data-testid="phone"]', '13800138000');
  await page.fill('[data-testid="password"]', '123456');
  await page.click('[data-testid="submit"]');
  await expect(page).toHaveURL('/home');
});
