Cursor Talk To Figma MCP代码质量保障:测试与CI/CD流程
引言:为什么代码质量对MCP项目至关重要
你是否曾经历过这样的困境:开发的MCP(Model Context Protocol)插件在本地运行完美,但部署到生产环境后却频繁崩溃?或者团队协作中,一个微小的代码变更就引发了连锁反应,导致整个系统瘫痪?对于Cursor Talk To Figma MCP这类需要与Figma实时通信的工具而言,代码质量问题不仅影响开发效率,更直接损害用户体验和项目可信度。
本文将深入探讨如何为Cursor Talk To Figma MCP构建完整的代码质量保障体系,包括测试策略设计、CI/CD流程实现以及质量监控体系。通过本文,你将学习到:
- 如何针对MCP项目特点设计测试策略
- 如何利用Docker容器化技术构建可靠的部署流程
- 如何实现自动化测试与持续集成
- 如何建立有效的代码质量监控机制
一、MCP项目测试策略设计
1.1 测试金字塔在MCP项目中的应用
传统的测试金字塔模型(单元测试、集成测试、端到端测试)同样适用于MCP项目,但需要根据其特性进行调整:
Cursor Talk To Figma MCP作为一个基于WebSocket与Figma进行实时通信的插件,其测试策略应重点关注以下几个方面:
- 协议兼容性:确保与Figma API的通信符合规范
- 数据验证:验证Zod模式定义的数据结构正确性
- 并发处理:测试多客户端同时连接时的稳定性
- 错误恢复:模拟网络中断等异常情况的恢复能力
1.2 现有项目测试现状分析
通过对Cursor Talk To Figma MCP项目结构和代码的分析,我们发现当前测试覆盖率存在明显不足:
// package.json 中缺少测试相关依赖
{
"devDependencies": {
"@types/bun": "latest",
"bun-types": "^1.2.5",
"tsup": "^8.4.0",
"typescript": "^5.0.0"
}
}
项目中未发现明确的测试脚本或测试文件,这意味着当前版本可能完全依赖手动测试,存在以下风险:
- 回归风险:代码变更可能引入未被发现的bug
- 质量盲区:无法量化代码质量指标
- 协作障碍:缺乏测试保障,影响团队协作效率
- 部署风险:生产环境部署前缺乏自动化验证
二、构建完整的测试体系
2.1 单元测试框架选型与配置
针对TypeScript项目,推荐使用Vitest作为测试框架,结合Bun运行时可获得最佳性能:
# 安装测试依赖
bun add -D vitest @types/node @testing-library/jest-dom
# 添加测试脚本到package.json
修改package.json文件,添加测试相关脚本:
{
"scripts": {
"test": "vitest run",
"test:watch": "vitest",
"test:coverage": "vitest run --coverage",
"test:ui": "vitest --ui"
}
}
2.2 核心功能单元测试示例
以server.ts中的filterFigmaNode函数为例,实现单元测试:
// src/__tests__/filterFigmaNode.test.ts
import { describe, it, expect } from 'vitest';
import { filterFigmaNode } from '../talk_to_figma_mcp/server';
describe('filterFigmaNode', () => {
it('should filter out VECTOR type nodes', () => {
const vectorNode = { id: '1', type: 'VECTOR', name: 'Vector' };
expect(filterFigmaNode(vectorNode)).toBeNull();
});
it('should convert RGBA colors to hex format', () => {
const nodeWithColor = {
id: '2',
type: 'RECTANGLE',
name: 'Colored Rect',
fills: [{
color: { r: 1, g: 1, b: 1, a: 1 },
type: 'SOLID'
}]
};
const filtered = filterFigmaNode(nodeWithColor);
expect(filtered?.fills[0].color).toBe('#ffffffff');
});
it('should preserve essential node properties', () => {
const complexNode = {
id: '3',
type: 'FRAME',
name: 'Test Frame',
x: 100,
y: 200,
width: 300,
height: 400,
cornerRadius: 8,
children: [
{ id: '4', type: 'TEXT', name: 'Test Text', characters: 'Hello' },
{ id: '5', type: 'VECTOR', name: 'Should be filtered' }
]
};
const filtered = filterFigmaNode(complexNode);
expect(filtered).toHaveProperty('id', '3');
expect(filtered).toHaveProperty('name', 'Test Frame');
expect(filtered).toHaveProperty('cornerRadius', 8);
expect(filtered?.children).toHaveLength(1);
expect(filtered?.children[0].type).toBe('TEXT');
});
});
2.3 WebSocket通信集成测试
MCP项目核心功能依赖WebSocket通信,可以使用ws库的测试工具进行集成测试:
// src/__tests__/websocket.test.ts
import { describe, it, expect, beforeAll, afterAll, vi } from 'vitest';
import WebSocket from 'ws';
import { createServer } from 'http';
import { McpServer } from '@modelcontextprotocol/sdk/server/mcp';
describe('WebSocket Communication', () => {
let server: any;
let wss: WebSocket.Server;
beforeAll(() => {
// 启动测试WebSocket服务器
const httpServer = createServer();
wss = new WebSocket.Server({ server });
// 设置MCP服务器
const mcpServer = new McpServer({ name: "TestMCP", version: "1.0.0" });
// 注册测试工具...
server = httpServer.listen(3000);
});
afterAll(() => {
wss.close();
server.close();
});
it('should establish connection and handle commands', async () => {
return new Promise((resolve, reject) => {
const ws = new WebSocket('ws://localhost:3000');
ws.on('open', () => {
ws.send(JSON.stringify({
id: 'test-command',
type: 'get_document_info'
}));
});
ws.on('message', (data) => {
const response = JSON.parse(data.toString());
expect(response.id).toBe('test-command');
expect(response).toHaveProperty('result');
ws.close();
resolve(true);
});
ws.on('error', reject);
});
});
it('should handle invalid commands gracefully', async () => {
// 测试无效命令处理...
});
it('should maintain connection stability under load', async () => {
// 测试连接稳定性...
});
});
2.4 端到端测试实现
使用Playwright进行端到端测试,验证MCP插件与Figma的集成效果:
// e2e/figma-integration.spec.ts
import { test, expect } from '@playwright/test';
test('should connect to Figma and retrieve document info', async ({ page }) => {
// 启动MCP服务器
const serverProcess = await test.step('Start MCP server', async () => {
const process = require('child_process').spawn('bun', ['run', 'src/socket.ts']);
// 等待服务器启动...
return process;
});
// 模拟Figma插件环境
await page.goto('http://localhost:3000/ui.html');
// 验证UI元素
await expect(page.locator('h1')).toContainText('Cursor Talk to Figma');
// 测试"获取文档信息"功能
await page.click('button:has-text("Get Document Info")');
await expect(page.locator('.result')).toContainText('Document ID:');
// 清理
serverProcess.kill();
});
2.5 Zod模式验证测试
针对项目中使用Zod进行的数据验证,添加专门的测试确保模式定义正确:
// src/__tests__/zod-schemas.test.ts
import { describe, it, expect } from 'vitest';
import { z } from 'zod';
// 导入项目中的Zod模式
describe('Zod Schema Validation', () => {
it('should validate frame creation parameters', () => {
const FrameSchema = z.object({
x: z.number(),
y: z.number(),
width: z.number().positive(),
height: z.number().positive(),
name: z.string().optional(),
// 其他属性...
});
// 测试有效数据
const validData = { x: 10, y: 20, width: 100, height: 200 };
expect(FrameSchema.safeParse(validData).success).toBe(true);
// 测试无效数据
const invalidData = { x: '10', y: 20, width: -100, height: 200 };
const result = FrameSchema.safeParse(invalidData);
expect(result.success).toBe(false);
// 验证错误信息
if (!result.success) {
expect(result.error.issues).toHaveLength(2);
expect(result.error.issues[0].path).toContain('x');
expect(result.error.issues[1].path).toContain('width');
}
});
});
三、CI/CD流程构建
3.1 Docker容器化部署方案

3.3 持续部署策略与环境管理
针对不同环境的部署需求,建议采用以下分支策略:
环境配置管理建议:
/config
/development
config.json
.env
/staging
config.json
.env
/production
config.json
.env.example # 不包含实际密钥
使用dotenv管理环境变量:
// src/config/env.ts
import dotenv from 'dotenv';
import path from 'path';
// 根据NODE_ENV加载不同环境配置
const env = process.env.NODE_ENV || 'development';
dotenv.config({ path: path.resolve(__dirname, `../../config/${env}/.env`) });
export const config = {
port: process.env.PORT || 3055,
logLevel: process.env.LOG_LEVEL || 'info',
figmaApiUrl: process.env.FIGMA_API_URL || 'https://api.figma.com',
// 其他配置...
};
四、代码质量监控与改进
4.1 静态代码分析工具集成
添加ESLint和Prettier配置,确保代码风格一致性:
# 安装开发依赖
bun add -D eslint @typescript-eslint/eslint-plugin @typescript-eslint/parser prettier eslint-config-prettier
创建ESLint配置文件.eslintrc.js:
module.exports = {
parser: '@typescript-eslint/parser',
extends: [
'eslint:recommended',
'plugin:@typescript-eslint/recommended',
'prettier'
],
plugins: ['@typescript-eslint'],
rules: {
// 强制使用类型定义
'@typescript-eslint/explicit-module-boundary-types': 'error',
// 禁止未使用的变量
'@typescript-eslint/no-unused-vars': ['error', { argsIgnorePattern: '^_' }],
// 强制使用接口而非类型别名
'@typescript-eslint/consistent-type-definitions': ['error', 'interface'],
// 其他规则...
}
};
添加lint脚本到package.json:
{
"scripts": {
"lint": "eslint src/**/*.ts",
"lint:fix": "eslint src/**/*.ts --fix",
"format": "prettier --write src/**/*.ts"
}
}
4.2 代码覆盖率目标与监控
设置明确的代码覆盖率目标,并在CI流程中进行强制检查:
// vitest.config.ts
import { defineConfig } from 'vitest/config';
export default defineConfig({
test: {
coverage: {
provider: 'v8',
reporter: ['text', 'lcov', 'clover'],
lines: 80, // 行覆盖率目标
functions: 80, // 函数覆盖率目标
branches: 70, // 分支覆盖率目标
statements: 80, // 语句覆盖率目标
include: ['src/**/*.ts'],
exclude: ['src/**/*.test.ts', 'src/**/__tests__/**']
}
}
});
4.3 性能基准测试
使用Benchmark.js添加性能基准测试,监控关键函数性能:
// src/__benchmarks__/filter-node.bench.ts
import { describe, bench, expect } from 'vitest';
import { filterFigmaNode } from '../talk_to_figma_mcp/server';
import { complexNodeFixture } from '../__fixtures__/nodes';
describe('filterFigmaNode performance', () => {
bench('filter complex node with 50 children', () => {
filterFigmaNode(complexNodeFixture);
});
bench('filter node with deep nesting (10 levels)', () => {
// 测试深度嵌套节点过滤性能...
});
bench('filter node with large text content', () => {
// 测试大文本节点过滤性能...
});
});
五、实施指南与最佳实践
