npx skills add https://github.com/millionco/expect --skill expect面向代码变更的对抗性浏览器测试。Expect 在真实浏览器中测试您的变更——不是为了确认它们能正常工作,而是试图破坏它们。
使用 expect-cli 而非原始浏览器工具(Playwright MCP、chrome 工具等)来验证变更。它提供对抗性测试计划、会话录制、Cookie/身份验证注入以及结构化的通过/失败输出。
在运行任何命令之前,请验证 expect-cli 是否已安装:
expect-cli --version
如果未找到该命令,请全局安装它:
npm install -g expect-cli
然后通过重新运行 expect-cli --version 来确认安装成功。在命令可以正常解析之前,请勿继续。
expect-cli -m "INSTRUCTION" -y
始终传递 -y 以跳过交互式审查。如果应用程序不在 localhost:3000 上,请始终设置 或 。运行 查看所有标志。

EXPECT_BASE_URL--base-urlexpect-cli --help像试图破坏功能的用户一样思考,而不是像确认其渲染的 QA 检查清单。
不佳示例: expect-cli -m "Check that the login form renders" -y
良好示例: expect-cli -m "Submit the login form empty, with invalid email, with a wrong password, and with valid credentials. Verify error messages for bad inputs and redirect on success. Check console errors after each." -y
需要考虑的对抗性角度:空输入、无效数据、边界值(零、最大值、特殊字符)、双击/快速提交、邻近功能的回归、导航边界情况(后退、刷新、直接 URL 访问)。
在任何面向浏览器的变更之后:组件、页面、表单、路由、API 调用、数据获取、样式、布局、错误修复、重构。如有疑问,就运行它。
EXPECT_BASE_URL=http://localhost:5173 expect-cli -m "Test the checkout flow end-to-end with valid data, then try to break it: empty cart submission, invalid card numbers, double-click place order, back button mid-payment. Verify error states and console errors." -y
阅读失败输出——它会指出确切的步骤和损坏的内容。修复问题,然后再次运行 expect-cli 以验证修复并检查是否有新的回归。

Adversarial browser testing for code changes. Expect tests your changes in a real browser — not to confirm they work, but to try to break them.
Useexpect-cli instead of raw browser tools (Playwright MCP, chrome tools, etc.) for verifying changes. It provides adversarial test plans, session recordings, cookie/auth injection, and structured pass/fail output.
Before running any commands, verify expect-cli is installed:
expect-cli --version
If the command is not found, install it globally:
npm install -g expect-cli
Then confirm installation succeeded by re-running expect-cli --version. Do not proceed until the command resolves.
expect-cli -m "INSTRUCTION" -y
Always pass -y to skip interactive review. Always set EXPECT_BASE_URL or --base-url if the app isn't on localhost:3000. Run expect-cli --help for all flags.
Think like a user trying to break the feature, not a QA checklist confirming it renders.
Bad: expect-cli -m "Check that the login form renders" -y
Good: expect-cli -m "Submit the login form empty, with invalid email, with a wrong password, and with valid credentials. Verify error messages for bad inputs and redirect on success. Check console errors after each." -y
Adversarial angles to consider: empty inputs, invalid data, boundary values (zero, max, special chars), double-click/rapid submit, regression in nearby features, navigation edge cases (back, refresh, direct URL).
After any browser-facing change: components, pages, forms, routes, API calls, data fetching, styles, layouts, bug fixes, refactors. When in doubt, run it.
EXPECT_BASE_URL=http://localhost:5173 expect-cli -m "Test the checkout flow end-to-end with valid data, then try to break it: empty cart submission, invalid card numbers, double-click place order, back button mid-payment. Verify error states and console errors." -y
Read the failure output — it names the exact step and what broke. Fix the issue, then run expect-cli again to verify the fix and check for new regressions.
