Uninstall

Extensions often open a feedback page when uninstalled, asking users why they removed the extension. Register this page's URL in your extension with chrome.runtime.setUninstallURL().

playwright-webext lets you trigger uninstallation from your test with extension.uninstall(), without navigating Chromium's extension management UI or handling a confirmation dialog.

test('uninstall', async ({ extension }) => {
  await extension.uninstall();
  // ...check uninstall action
});

Example​

Capture the feedback page and check its heading.

test/uninstall.spec.ts
import { expect } from '@playwright/test';
import { test } from 'playwright-webext';

test('opens the feedback page after uninstalling', async ({ extension }) => {
  await extension.uninstall();

  const feedbackPage = await extension.pollForPage('https://example.com/uninstall');
  await expect(feedbackPage.getByRole('heading')).toHaveText('Why did you uninstall?');
});
