使用indexedDB的playwright

Question

有没有可能以某种方式与indexeddb交互？

我想使用indexeddb中的测试数据来测试UI。

我正在使用文档https://developer.mozilla.org/en-US/docs/Web/API/IDBFactory中的代码，并得到错误

 indexedDB is not defined 
window is not defined

是的，您可以使用page.evaluate在页面中执行JavaScript：https://playwright.dev/docs/api/class-page#page-evaluate

// @ts-check
const playwright = require('playwright');

(async () => {
  // Try to add 'firefox' to the list ↓
  for (const browserType of [playwright.chromium, playwright.firefox, playwright.webkit]) {
    const browser = await browserType.launch();
    const context = await browser.newContext();
    const page = await context.newPage();
    await page.goto('https://example.org/');
    console.log(await page.evaluate(() => {
      return typeof window.indexedDB
    }));
    await browser.close();
  }
})();

确保将您想要在浏览器中与Node.js共享的任何值作为第二个参数进行传递，请参见此处：https://playwright.dev/docs/next/evaluating
