Playwright Test
Playwright Test provides a test
function to declare tests and expect
function to write assertions.
import { test, expect } from '@playwright/test';
test('basic test', async ({ page }) => {
await page.goto('https://playwright.dev/');
const name = await page.innerText('.navbar__title');
expect(name).toBe('Playwright');
});
Methods
test
Added in: v1.10Declares a test.
test(title, body)
test(title, details, body)
Usage
import { test, expect } from '@playwright/test';
test('basic test', async ({ page }) => {
await page.goto('https://playwright.dev/');
// ...
});
Tags
You can tag tests by providing additional test details. Alternatively, you can include tags in the test title. Note that each tag must start with @
symbol.
import { test, expect } from '@playwright/test';
test('basic test', {
tag: '@smoke',
}, async ({ page }) => {
await page.goto('https://playwright.dev/');
// ...
});
test('another test @smoke', async ({ page }) => {
await page.goto('https://playwright.dev/');
// ...
});
Test tags are displayed in the test report, and are available to a custom reporter via TestCase.tags
property.
You can also filter tests by their tags during test execution:
- in the command line;
- in the config with testConfig.grep and testProject.grep;
Learn more about tagging.
Annotations
You can annotate tests by providing additional test details.
import { test, expect } from '@playwright/test';
test('basic test', {
annotation: {
type: 'issue',
description: 'https://github.com/microsoft/playwright/issues/23180',
},
}, async ({ page }) => {
await page.goto('https://playwright.dev/');
// ...
});
Test annotations are displayed in the test report, and are available to a custom reporter via TestCase.annotations
property.
You can also add annotations during runtime by manipulating testInfo.annotations.

test('one', async ({ page }) => {
// ...
});
test('two', async ({ page }) => {
// ...
});
});
Anonymous group
You can also declare a test group without a title. This is convenient to give a group of tests a common option with test.use().
test.describe(() => {
test.use({ colorScheme: 'dark' });
test('one', async ({ page }) => {
// ...
});
test('two', async ({ page }) => {

Arguments
-
Group title.
-
details
Object (optional) Added in: v1.42#Additional details for all tests in the group.
-
A callback that is run immediately when calling test.describe(). Any tests declared in this callback will belong to the group.

Running tests in parallel.
// Run all the tests in the file concurrently using parallel workers.
test.describe.configure({ mode: 'parallel' });
test('runs in parallel 1', async ({ page }) => {});
test('runs in parallel 2', async ({ page }) => {}); -
Running tests serially, retrying from the start.
noteRunning serially is not recommended. It is usually better to make your tests isolated, so they can be run independently.
// Annotate tests as inter-dependent.
test.describe.configure({ mode: 'serial' });
test('runs first', async ({ page }) => {});
test('runs second', async ({ page }) => {}); -
Configuring retries and timeout for each test.
// Each test in the file will be retried twice and have a timeout of 20 seconds.
test.describe.configure({ retries: 2, timeout: 20_000 });
test('runs first', async ({ page }) => {});
test('runs second', async ({ page }) => {}); -
Run multiple describes in parallel, but tests inside each describe in order.

test.extend
Added in: v1.10Extends the test
object by defining fixtures and/or options that can be used in the tests.
Usage
First define a fixture and/or an option.
- TypeScript
- JavaScript
import { test as base } from '@playwright/test';
import { TodoPage } from './todo-page';
export type Options = { defaultItem: string };
// Extend basic test by providing a "defaultItem" option and a "todoPage" fixture.
export const test = base.extend<Options & { todoPage: TodoPage }>({
// Define an option and provide a default value.
// We can later override it in the config.
defaultItem: ['Do stuff', { option: true }],
// Define a fixture. Note that it can use built-in fixture "page"
// and a new option "defaultItem".
todoPage: async ({ page, defaultItem }, use) => {
const todoPage = new TodoPage(page);
await todoPage.goto();
await todoPage.addToDo(defaultItem);
await use(todoPage);
await todoPage.removeAll();
},
});
const base = require('@playwright/test');
const { TodoPage } = require('./todo-page');
// Extend basic test by providing a "defaultItem" option and a "todoPage" fixture.
exports.test = base.test.extend({
// Define an option and provide a default value.
// We can later override it in the config.
defaultItem: ['Do stuff', { option: true }],
// Define a fixture. Note that it can use built-in fixture "page"
// and a new option "defaultItem".
todoPage: async ({ page, defaultItem }, use) => {
const todoPage = new TodoPage(page);
await todoPage.goto();
await todoPage.addToDo(defaultItem);
await use(todoPage);
await todoPage.removeAll();
},
});
Then use the fixture in the test.
import { test } from './my-test';
test('test 1', async ({ todoPage }) => {
await todoPage.addToDo('my todo');
// ...
});
Configure the option in config file.
- TypeScript
- JavaScript
import { defineConfig } from '@playwright/test';
import type { Options } from './my-test';
export default defineConfig<Options>({
projects: [
{
name: 'shopping',
use: { defaultItem: 'Buy milk' },
},
{
name: 'wellbeing',
use: { defaultItem: 'Exercise!' },
},
]
});
// @ts-check
module.exports = defineConfig({
projects: [
{
name: 'shopping',
use: { defaultItem: 'Buy milk' },
},
{
name: 'wellbeing',
use: { defaultItem: 'Exercise!' },
},
]
});
Learn more about fixtures and parametrizing tests.
Arguments
-
An object containing fixtures and/or options. Learn more about fixtures format.
Returns
test.fail
Added in: v1.10Marks a test as "should fail". Playwright runs this test and ensures that it is actually failing. This is useful for documentation purposes to acknowledge that some functionality is broken until it is fixed.
To declare a "failing" test:
test.fail(title, body)
test.fail(title, details, body)
To annotate test as "failing" at runtime:
test.fail(condition, description)
test.fail(callback, description)
test.fail()
Usage
You can declare a test as failing, so that Playwright ensures it actually fails.
import { test, expect } from '@playwright/test';
test.fail('not yet ready', async ({ page }) => {
// ...
});
If your test fails in some configurations, but not all, you can mark the test as failing inside the test body based on some condition. We recommend passing a description
argument in this case.
import { test, expect } from '@playwright/test';
test('fail in WebKit', async ({ page, browserName }) => {
test.fail(browserName === 'webkit', 'This feature is not implemented for Mac yet');
// ...
});
You can mark all tests in a file or test.describe() group as "should fail" based on some condition with a single test.fail(callback, description)
call.
import { test, expect } from '@playwright/test';
test.fail(({ browserName }) => browserName === 'webkit', 'not implemented yet');
test('fail in WebKit 1', async ({ page }) => {
// ...
});
test('fail in WebKit 2', async ({ page }) => {
// ...
});
You can also call test.fail()
without arguments inside the test body to always mark the test as failed. We recommend declaring a failing test with test.fail(title, body)
instead.
import { test, expect } from '@playwright/test';
test('less readable', async ({ page }) => {
test.fail();
// ...
});
Arguments
-
title
string (optional) Added in: v1.42#Test title.
-
details
Object (optional) Added in: v1.42#See test() for test details description.
-
body
function(Fixtures, TestInfo) (optional) Added in: v1.42#Test body that takes one or two arguments: an object with fixtures and optional TestInfo.
-
Test is marked as "should fail" when the condition is
true
. -
callback
function(Fixtures):boolean (optional)#A function that returns whether to mark as "should fail", based on test fixtures. Test or tests are marked as "should fail" when the return value is
true
. -
description
string (optional)#Optional description that will be reflected in a test report.
test.fixme
Added in: v1.10Mark a test as "fixme", with the intention to fix it. Playwright will not run the test past the test.fixme()
call.
To declare a "fixme" test:
test.fixme(title, body)
test.fixme(title, details, body)
To annotate test as "fixme" at runtime:
test.fixme(condition, description)
test.fixme(callback, description)
test.fixme()
Usage
You can declare a test as to be fixed, and Playwright will not run it.
import { test, expect } from '@playwright/test';
test.fixme('to be fixed', async ({ page }) => {
// ...
});
If your test should be fixed in some configurations, but not all, you can mark the test as "fixme" inside the test body based on some condition. We recommend passing a description
argument in this case. Playwright will run the test, but abort it immediately after the test.fixme
call.
import { test, expect } from '@playwright/test';
test('to be fixed in Safari', async ({ page, browserName }) => {
test.fixme(browserName === 'webkit', 'This feature breaks in Safari for some reason');
// ...
});
You can mark all tests in a file or test.describe() group as "fixme" based on some condition with a single test.fixme(callback, description)
call.
import { test, expect } from '@playwright/test';
test.fixme(({ browserName }) => browserName === 'webkit', 'Should figure out the issue');
test('to be fixed in Safari 1', async ({ page }) => {
// ...
});
test('to be fixed in Safari 2', async ({ page }) => {
// ...
});
You can also call test.fixme()
without arguments inside the test body to always mark the test as failed. We recommend using test.fixme(title, body)
instead.

Changing test timeout.
test('very slow test', async ({ page }) => {
test.setTimeout(120000);
// ...
}); -
Changing timeout from a slow
beforeEach
orafterEach
hook. Note that this affects the test timeout that is shared withbeforeEach
/afterEach
hooks.test.beforeEach(async ({ page }, testInfo) => {
// Extend timeout for all tests running this hook by 30 seconds.
test.setTimeout(testInfo.timeout + 30000);
}); -
Changing timeout for a
beforeAll
orafterAll
hook. Note this affects the hook's timeout, not the test timeout.test.beforeAll(async () => {
// Set timeout for this hook.

test('test two', async () => { /* ... */ });
test('test three', async () => { /* ... */ });
});
Arguments
test.skip
Added in: v1.10Skip a test. Playwright will not run the test past the test.skip()
call.
Skipped tests are not supposed to be ever run. If you intent to fix the test, use test.fixme() instead.

If your test should be skipped in some configurations, but not all, you can skip the test inside the test body based on some condition. We recommend passing a description
argument in this case. Playwright will run the test, but abort it immediately after the test.skip
call.
import { test, expect } from '@playwright/test';
test('Safari-only test', async ({ page, browserName }) => {
test.skip(browserName !== 'webkit', 'This feature is Safari-only');
// ...

You can use TypeScript method decorators to turn a method into a step. Each call to the decorated method will show up as a step in the report.
function step(target: Function, context: ClassMethodDecoratorContext) {
return function replacementMethod(...args: any) {
const name = this.constructor.name + '.' + (context.name as string);
return test.step(name, async () => {
return await target.call(this, ...args);
});
};
}
class LoginPage {
constructor(readonly page: Page) {}
@step
async login() {
const account = { username: 'Alice', password: 's3cr3t' };
await this.page.getByLabel('Username or email address').fill(account.username);
await this.page.getByLabel('Password').fill(account.password);
await this.page.getByRole('button', { name: 'Sign in' }).click();
await expect(this.page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
}
}
test('example', async ({ page }) => {
const loginPage = new LoginPage(page);
await loginPage.login();
});
Boxing
When something inside a step fails, you would usually see the error pointing to the exact action that failed. For example, consider the following login step:
async function login(page) {
await test.step('login', async () => {
const account = { username: 'Alice', password: 's3cr3t' };
await page.getByLabel('Username or email address').fill(account.username);
await page.getByLabel('Password').fill(account.password);
await page.getByRole('button', { name: 'Sign in' }).click();
await expect(page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
});
}
test('example', async ({ page }) => {
await page.goto('https://github.com/login');
await login(page);
});
Error: Timed out 5000ms waiting for expect(locator).toBeVisible()
... error details omitted ...
8 | await page.getByRole('button', { name: 'Sign in' }).click();
> 9 | await expect(page.getByRole('button', { name: 'View profile and more' })).toBeVisible();
| ^
10 | });
As we see above, the test may fail with an error pointing inside the step. If you would like the error to highlight the "login" step instead of its internals, use the box
option. An error inside a boxed step points to the step call site.
async function login(page) {
await test.step('login', async () => {
// ...
}, { box: true }); // Note the "box" option here.
}
Error: Timed out 5000ms waiting for expect(locator).toBeVisible()
... error details omitted ...
14 | await page.goto('https://github.com/login');
> 15 | await login(page);
| ^
16 | });
You can also create a TypeScript decorator for a boxed step, similar to a regular step decorator above:
function boxedStep(target: Function, context: ClassMethodDecoratorContext) {
return function replacementMethod(...args: any) {
const name = this.constructor.name + '.' + (context.name as string);
return test.step(name, async () => {
return await target.call(this, ...args);
}, { box: true }); // Note the "box" option here.
};
}
class LoginPage {
constructor(readonly page: Page) {}
@boxedStep
async login() {
// ....
}
}
test('example', async ({ page }) => {
const loginPage = new LoginPage(page);
await loginPage.login(); // <-- Error will be reported on this line.
});
test.use
Added in: v1.10Specifies options or fixtures to use in a single test file or a test.describe() group. Most useful to set an option, for example set locale
to configure context
fixture.
Usage
import { test, expect } from '@playwright/test';
test.use({ locale: 'en-US' });
test('test with locale', async ({ page }) => {
// Default context and page have locale as specified
});
Arguments
-
options
TestOptions#An object with local options.
Details
test.use
can be called either in the global scope or inside test.describe
. It is an error to call it within beforeEach
or beforeAll
.
It is also possible to override a fixture by providing a function.
import { test, expect } from '@playwright/test';
test.use({
locale: async ({}, use) => {
// Read locale from some configuration file.
const locale = await fs.promises.readFile('test-locale', 'utf-8');
await use(locale);
},
});
test('test with locale', async ({ page }) => {
// Default context and page have locale as specified
});
Properties
test.expect
Added in: v1.10expect
function can be used to create test assertions. Read more about test assertions.
Usage
test('example', async ({ page }) => {
await test.expect(page).toHaveTitle('Title');
});
Type
Deprecated
test.describe.parallel
Added in: v1.10See test.describe.configure() for the preferred way of configuring the execution mode.
Declares a group of tests that could be run in parallel. By default, tests in a single test file run one after another, but using test.describe.parallel() allows them to run in parallel.
test.describe.parallel(title, callback)
test.describe.parallel(callback)
test.describe.parallel(title, details, callback)
Usage
test.describe.parallel('group', () => {
test('runs in parallel 1', async ({ page }) => {});
test('runs in parallel 2', async ({ page }) => {});
});
Note that parallel tests are executed in separate processes and cannot share any state or global variables. Each of the parallel tests executes all relevant hooks.
You can also omit the title.
test.describe.parallel(() => {
// ...
});
Arguments
-
Group title.
-
details
Object (optional) Added in: v1.42#See test.describe() for details description.
-
A callback that is run immediately when calling test.describe.parallel(). Any tests added in this callback will belong to the group.
test.describe.parallel.only
Added in: v1.10See test.describe.configure() for the preferred way of configuring the execution mode.
Declares a focused group of tests that could be run in parallel. This is similar to test.describe.parallel(), but focuses the group. If there are some focused tests or suites, all of them will be run but nothing else.
test.describe.parallel.only(title, callback)
test.describe.parallel.only(callback)
test.describe.parallel.only(title, details, callback)
Usage
test.describe.parallel.only('group', () => {
test('runs in parallel 1', async ({ page }) => {});
test('runs in parallel 2', async ({ page }) => {});
});
You can also omit the title.
test.describe.parallel.only(() => {
// ...
});
Arguments
-
Group title.
-
details
Object (optional) Added in: v1.42#See test.describe() for details description.
-
A callback that is run immediately when calling test.describe.parallel.only(). Any tests added in this callback will belong to the group.
test.describe.serial
Added in: v1.10See test.describe.configure() for the preferred way of configuring the execution mode.
Declares a group of tests that should always be run serially. If one of the tests fails, all subsequent tests are skipped. All tests in a group are retried together.
Using serial is not recommended. It is usually better to make your tests isolated, so they can be run independently.
test.describe.serial(title, callback)
test.describe.serial(title)
test.describe.serial(title, details, callback)
Usage
test.describe.serial('group', () => {
test('runs first', async ({ page }) => {});
test('runs second', async ({ page }) => {});
});
You can also omit the title.
test.describe.serial(() => {
// ...
});
Arguments
-
Group title.
-
details
Object (optional) Added in: v1.42#See test.describe() for details description.
-
A callback that is run immediately when calling test.describe.serial(). Any tests added in this callback will belong to the group.
test.describe.serial.only
Added in: v1.10See test.describe.configure() for the preferred way of configuring the execution mode.
Declares a focused group of tests that should always be run serially. If one of the tests fails, all subsequent tests are skipped. All tests in a group are retried together. If there are some focused tests or suites, all of them will be run but nothing else.

You can also omit the title.
test.describe.serial.only(() => {
// ...
});
Arguments
-
Group title.
-
details
Object (optional) Added in: v1.42#See test.describe() for details description.
