调研方向

从链接的 pw-repro 仓库中的最小复现开始，比较其在 TypeScript 5.6.3 和 5.7.2 下的行为。以受影响的 Playwright 扩展代码作为重点案例，然后参考链接的 Playwright issue 和 TypeScript 的回归行为。当受影响的值不再被报告为 any，并且 5.7.2 的类型检查错误得到解决时，即视为完成。

💻 Code

Minimal repro available here:
https://github.com/mrmckeb/pw-repro

The Playwright team are also able to reproduce:
https://github.com/microsoft/playwright/issues/33763

The affected code (from the repro) is:

import { test as base, expect } from "@playwright/test";

const test = base.extend({
  // baseUrl, page, use are now `any`
  page: async ({ baseURL, page }, use) => {
    await page.goto(baseURL);
    await use(page);
  },
});
🙁 Actual behavior

Types that were previously available are now typed as any. JSDoc continues to work as expected.

🙂 Expected behavior

Types behave as they did in TypeScript 5.6.3.

Additional information about the issue

We found this issue when upgrading from 5.6.3 to 5.7.2. I couldn't find a related issue here, so raised it at the Playwright repo to at least verify that they could reproduce and that they didn't think it was an issue with their types.

The Playwright team also confirmed that they have 71 new errors across 41 files when moving to TypeScript 5.7.2.
