TLS Client Certificates

Playwright now allows to supply client-side certificates, so that server can verify them, as specified by TLS Client Authentication.

When client certificates are specified, all browser traffic is routed through a proxy that establishes the secure TLS connection, provides client certificates to the server and validates server certificates.

The following snippet sets up a client certificate for https://example.com:

import { defineConfig } from '@playwright/test';

export default defineConfig({
  // ...
  use: {
    clientCertificates: [{
      origin: 'https://example.com',
      certPath: './cert.pem',
      keyPath: './key.pem',
      passphrase: 'mysecretpassword',
    }],
  },
  // ...
});

You can also provide client certificates to a particular test project or as a parameter of browser.newContext() and apiRequest.newContext().

--only-changed cli option

New CLI option --only-changed allows to only run test files that have been changed since the last git commit or from a specific git "ref".

# Only run test files with uncommitted changes
npx playwright test --only-changed

# Only run test files changed relative to the "main" branch
npx playwright test --only-changed=main

Component Testing: New router fixture

This release introduces an experimental router fixture to intercept and handle network requests in component testing.
There are two ways to use the router fixture:

  • Call router.route(url, handler) that behaves similarly to page.route().
  • Call router.use(handlers) and pass MSW library request handlers to it.

Here is an example of reusing your existing MSW handlers in the test.

import { handlers } from '@src/mocks/handlers';

test.beforeEach(async ({ router }) => {
  // install common handlers before each test
  await router.use(...handlers);
});

test('example test', async ({ mount }) => {
  // test as usual, your handlers are active
  // ...
});

This fixture is only available in component tests.

UI Mode / Trace Viewer Updates

  • Test annotations are now shown in UI mode.
  • Content of text attachments is now rendered inline in the attachments pane.
  • New setting to show/hide routing actions like route.continue().
  • Request method and status are shown in the network details tab.
  • New button to copy source file location to clipboard.
  • Metadata pane now displays the baseURL.

Miscellaneous

Possibly breaking change

Fixture values that are array of objects, when specified in the test.use() block, may require being wrapped into a fixture tuple. This is best seen on the example:

import { test as base } from '@playwright/test';

// Define an option fixture that has an "array of objects" value
type User = { name: string, password: string };
const test = base.extend<{ users: User[] }>({
  users: [ [], { option: true } ],
}); 

// Specify option value in the test.use block.
test.use({
  // WRONG: this syntax may not work for you
  users: [
    { name: 'John Doe', password: 'secret' },
    { name: 'John Smith', password: 's3cr3t' },
  ],
  // CORRECT: this syntax will work. Note extra [] around the value, and the "scope" property.
  users: [[
    { name: 'John Doe', password: 'secret' },
    { name: 'John Smith', password: 's3cr3t' },
  ], { scope: 'test' }],
});

test('example test', async () => {
  // ...
});
