Network Replay

Now you can record network traffic into a HAR file and re-use the data in your tests.

To record network into HAR file:

npx playwright open --save-har=github.har.zip https://github.com/microsoft

Alternatively, you can record HAR programmatically:

const context = await browser.newContext({
  recordHar: { path: 'github.har.zip' }
});
// ... do stuff ...
await context.close();

Use the new methods page.routeFromHAR() or browserContext.routeFromHAR() to serve matching responses from the HAR file:

await context.routeFromHAR('github.har.zip');

Read more in our documentation.

Advanced Routing

You can now use route.fallback() to defer routing to other handlers.

Consider the following example:

// Remove a header from all requests.
test.beforeEach(async ({ page }) => {
  await page.route('**/*', route => {
    const headers = route.request().headers();
    delete headers['if-none-match'];
    route.fallback({ headers });
  });
});

test('should work', async ({ page }) => {
  await page.route('**/*', route => {
    if (route.request().resourceType() === 'image')
      route.abort();
    else
      route.fallback();
  });
});

Note that the new methods page.routeFromHAR() and browserContext.routeFromHAR() also participate in routing and could be deferred to.

Web-First Assertions Update

• New method expect(locator).toHaveValues() that asserts all selected values of <select multiple> element.
• Methods expect(locator).toContainText() and expect(locator).toHaveText() now accept ignoreCase option.

Component Tests Update

• Support for Vue2 via the @playwright/experimental-ct-vue2 package.
• Support for component tests for create-react-app with components in .js files.

Read more about component testing with Playwright.

Miscellaneous

• If there's a service worker that's in your way, you can now easily disable it with a new context option serviceWorkers:

  // playwright.config.ts
  export default {
    use: {
      serviceWorkers: 'block',
    }
  }

• Using .zip path for recordHar context option automatically zips the resulting HAR:

  const context = await browser.newContext({
    recordHar: {
      path: 'github.har.zip',
    }
  });

• If you intend to edit HAR by hand, consider using the "minimal" HAR recording mode
  that only records information that is essential for replaying:

  const context = await browser.newContext({
    recordHar: {
      path: 'github.har.zip',
      mode: 'minimal',
    }
  });

• Playwright now runs on Ubuntu 22 amd64 and Ubuntu 22 arm64. We also publish new docker image mcr.microsoft.com/playwright:v1.23.0-focal.

⚠️ Breaking Changes ⚠️

WebServer is now considered "ready" if request to the specified port has any of the following HTTP status codes:

• 200-299
• 300-399 (new)
• 400, 401, 402, 403 (new)
