MinorContains breaking changesPlaywright 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 optionNew 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
router fixtureThis release introduces an experimental router fixture to intercept and handle network requests in component testing.
There are two ways to use the router fixture:
router.route(url, handler) that behaves similarly to page.route().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.
baseURL.maxRetries option in apiRequestContext.fetch() which retries on the ECONNRESET network error.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 () => {
// ...
});
This version was also tested against the following stable channels:
