如何在Mac端基于C#后端运行Playwright Safari自动化测试

一、Mac Mini端准备 #

先在你的Mac Mini上配置Playwright Server，替代原有的Selenium Server：

1. 安装Node.js（要求版本16及以上）
2. 全局安装Playwright：

   npm install -g playwright
   

3. 安装Safari对应的Playwright驱动：

   playwright install safari
   

4. 启用Safari远程自动化：打开Safari偏好设置→高级→勾选「显示开发菜单」，再在顶部菜单「开发」中选择「允许远程自动化」
5. 启动Playwright Server，允许外部设备访问：

   playwright server --host 0.0.0.0 --port 4444
   

二、Windows端测试代码改造 #

替换原有的Selenium RemoteWebDriver逻辑，改用Playwright的远程连接方案：

1. 依赖准备 #

确保测试项目已安装以下NuGet包：

• Microsoft.Playwright
• Reqnroll
• MSTest.TestFramework 和 MSTest.TestAdapter

2. 替换Driver定义 #

把原有的RemoteWebDriver替换为Playwright核心对象：

using Microsoft.Playwright;
using Reqnroll;
using Microsoft.VisualStudio.TestTools.UnitTesting;

[TestClass]
[Binding]
public class Hooks
{
    protected static IPlaywright Playwright { get; set; }
    protected static IBrowser Browser { get; set; }
    protected static IPage Page { get; set; }
    private readonly string _macMiniWsEndpoint = "ws://00.000.0.00:4444/playwright/safari"; // 替换为你的Mac Mini实际IP

3. 修改BeforeScenario逻辑 #

替换原Selenium初始化代码为Playwright远程连接逻辑：

[BeforeScenario]
public async Task BeforeScenario()
{
    // 初始化Playwright实例
    Playwright = await Playwright.CreateAsync();

    // 连接到Mac Mini上的Playwright Server
    Browser = await Playwright.Safari.ConnectAsync(new BrowserConnectOptions
    {
        WsEndpoint = _macMiniWsEndpoint
    });

    // 创建最大化窗口的页面（对应原Selenium的窗口最大化操作）
    Page = await Browser.NewPageAsync(new BrowserNewPageOptions
    {
        Args = new[] { "--start-maximized" },
        // 匹配原Selenium的PageLoadStrategy.Normal，对应Playwright的Load状态
        DefaultNavigationWaitUntil = WaitUntilState.Load
    });
}

4. 添加AfterScenario清理逻辑 #

测试结束后释放Playwright资源：

[AfterScenario]
public async Task AfterScenario()
{
    await Page.CloseAsync();
    await Browser.CloseAsync();
    Playwright.Dispose();
}

关键注意事项 #

• Playwright使用WebSocket连接远程Server，端点格式为ws://<mac-ip>:<port>/playwright/safari，和Selenium的HTTP端点格式不同
• 确保Mac Mini的防火墙允许4444端口的WebSocket流量
• 若需单独调整某个页面的加载策略，可在Page.GotoAsync时通过WaitUntil参数指定，例如：

  await Page.GotoAsync("https://your-test-url.com", new PageGotoOptions
  {
      WaitUntil = WaitUntilState.Load
  });
