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: v1.10 test.test

Declares 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:

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.

Learn more about test annotations.

Arguments

test.afterAll​

Added in: v1.10 test.test.afterAll

Declares an afterAll hook that is executed once per worker after all tests.

When called in the scope of a test file, runs after all tests in the file. When called inside a test.describe() group, runs after all tests in the group.

Usage

test.afterAll(async () => {
  console.log('Done with tests');
  // ...
});

Alternatively, you can declare a hook with a title.

test.afterAll('Teardown', async () => {
  console.log('Done with tests');
  // ...
});

Arguments

Details

When multiple afterAll hooks are added, they will run in the order of their registration.

Note that worker process is restarted on test failures, and afterAll hook runs again in the new worker. Learn more about workers and failures.

Playwright will continue running all applicable hooks even if some of them have failed.

  • test.afterAll(hookFunction)
  • test.afterAll(title, hookFunction)

test.afterEach​

Added in: v1.10 test.test.afterEach

Declares an afterEach hook that is executed after each test.

When called in the scope of a test file, runs after each test in the file. When called inside a test.describe() group, runs after each test in the group.

You can access all the same Fixtures as the test body itself, and also the TestInfo object that gives a lot of useful information. For example, you can check whether the test succeeded or failed.

  • test.afterEach(hookFunction)
  • test.afterEach(title, hookFunction)

Usage

example.spec.ts
import { test, expect } from '@playwright/test';

test.afterEach(async ({ page }) => {
  console.log(`Finished ${test.info().title} with status ${test.info().status}`);

  if (test.info().status !== test.info().expectedStatus)
    console.log(`Did not run as expected, ended up at ${page.url()}`);
});

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

Alternatively, you can declare a hook with a title.

example.spec.ts
test.afterEach('Status check', async ({ page }) => {
  if (test.info().status !== test.info().expectedStatus)
    console.log(`Did not run as expected, ended up at ${page.url()}`);
});

Arguments

Details

When multiple afterEach hooks are added, they will run in the order of their registration.

Playwright will continue running all applicable hooks even if some of them have failed.

test.beforeAll​

Added in: v1.10 test.test.beforeAll

Declares a beforeAll hook that is executed once per worker process before all tests.

When called in the scope of a test file, runs before all tests in the file. When called inside a test.describe() group, runs before all tests in the group.

You can use test.afterAll() to teardown any resources set up in beforeAll.

  • test.beforeAll(hookFunction)
  • test.beforeAll(title, hookFunction)

Usage

example.spec.ts
import { test, expect } from '@playwright/test';

test.beforeAll(async () => {
  console.log('Before tests');
});

test.afterAll(async () => {
  console.log('After tests');
});

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

Alternatively, you can declare a hook with a title.

example.spec.ts
test.beforeAll('Setup', async () => {
  console.log('Before tests');
});

Arguments

Details

When multiple beforeAll hooks are added, they will run in the order of their registration.

Note that worker process is restarted on test failures, and beforeAll hook runs again in the new worker. Learn more about workers and failures.

Playwright will continue running all applicable hooks even if some of them have failed.

test.beforeEach​

Added in: v1.10 test.test.beforeEach

Declares a beforeEach hook that is executed before each test.

When called in the scope of a test file, runs before each test in the file. When called inside a test.describe() group, runs before each test in the group.

You can access all the same Fixtures as the test body itself, and also the TestInfo object that gives a lot of useful information. For example, you can navigate the page before starting the test.

You can use test.afterEach() to teardown any resources set up in beforeEach.

  • test.beforeEach(hookFunction)
  • test.beforeEach(title, hookFunction)

Usage

example.spec.ts
import { test, expect } from '@playwright/test';

test.beforeEach(async ({ page }) => {
  console.log(`Running ${test.info().title}`);
  await page.goto('https://my.start.url/');
});

test('my test', async ({ page }) => {
  expect(page.url()).toBe('https://my.start.url/');
});

Alternatively, you can declare a hook with a title.

example.spec.ts
test.beforeEach('Open start URL', async ({ page }) => {
  console.log(`Running ${test.info().title}`);
  await page.goto('https://my.start.url/');
});

Arguments

Details

When multiple beforeEach hooks are added, they will run in the order of their registration.

Playwright will continue running all applicable hooks even if some of them have failed.

test.describe​

Added in: v1.10 test.test.describe

Declares a group of tests.

  • test.describe(title, callback)
  • test.describe(callback)
  • test.describe(title, details, callback)

Usage

You can declare a group of tests with a title. The title will be visible in the test report as a part of each test's title.

test.describe('two tests', () => {
  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 }) => {
    // ...
  });
});

Tags

You can tag all tests in a group by providing additional details. Note that each tag must start with @ symbol.

import { test, expect } from '@playwright/test';

test.describe('two tagged tests', {
  tag: '@smoke',
}, () => {
  test('one', async ({ page }) => {
    // ...
  });

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

Learn more about tagging.

Annotations

You can annotate all tests in a group by providing additional details.

import { test, expect } from '@playwright/test';

test.describe('two annotated tests', {
  annotation: {
    type: 'issue',
    description: 'https://github.com/microsoft/playwright/issues/23180',
  },
}, () => {
  test('one', async ({ page }) => {
    // ...
  });

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

Arguments

test.describe.configure​

Added in: v1.10 test.test.describe.configure

Configures the enclosing scope. Can be executed either on the top level or inside a describe. Configuration applies to the entire scope, regardless of whether it run before or after the test declaration.

Learn more about the execution modes here.

Usage

  • 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.

    note

    Running 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.describe.configure({ mode: 'parallel' });

    test.describe('A, runs in parallel with B', () => {
      test.describe.configure({ mode: 'default' });
      test('in order A1', async ({ page }) => {});
      test('in order A2', async ({ page }) => {});
    });

    test.describe('B, runs in parallel with A', () => {
      test.describe.configure({ mode: 'default' });
      test('in order B1', async ({ page }) => {});
      test('in order B2', async ({ page }) => {});
    });

Arguments

  • options Object (optional)

    • mode "default" | "parallel" | "serial" (optional)#

      Execution mode. Learn more about the execution modes here.

    • retries number (optional) Added in: v1.28#

      The number of retries for each test.

    • timeout number (optional) Added in: v1.28#

      Timeout for each test in milliseconds. Overrides testProject.timeout and testConfig.timeout.

test.describe.fixme​

Added in: v1.25 test.test.describe.fixme

Declares a test group similarly to test.describe(). Tests in this group are marked as "fixme" and will not be executed.

  • test.describe.fixme(title, callback)
  • test.describe.fixme(callback)
  • test.describe.fixme(title, details, callback)

Usage

test.describe.fixme('broken tests that should be fixed', () => {
  test('example', async ({ page }) => {
    // This test will not run
  });
});

You can also omit the title.

test.describe.fixme(() => {
  // ...
});

Arguments

test.describe.only​

Added in: v1.10 test.test.describe.only

Declares a focused group of tests. If there are some focused tests or suites, all of them will be run but nothing else.

  • test.describe.only(title, callback)
  • test.describe.only(callback)
  • test.describe.only(title, details, callback)

Usage

test.describe.only('focused group', () => {
  test('in the focused group', async ({ page }) => {
    // This test will run
  });
});
test('not in the focused group', async ({ page }) => {
  // This test will not run
});

You can also omit the title.

test.describe.only(() => {
  // ...
});

Arguments

test.describe.skip​

Added in: v1.10 test.test.describe.skip

Declares a skipped test group, similarly to test.describe(). Tests in the skipped group are never run.

  • test.describe.skip(title, callback)
  • test.describe.skip(title)
  • test.describe.skip(title, details, callback)

Usage

test.describe.skip('skipped group', () => {
  test('example', async ({ page }) => {
    // This test will not run
  });
});

You can also omit the title.

test.describe.skip(() => {
  // ...
});

Arguments

test.extend​

Added in: v1.10 test.test.extend

Extends 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.

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();
  },
});

Then use the fixture in the test.

example.spec.ts
import { test } from './my-test';

test('test 1', async ({ todoPage }) => {
  await todoPage.addToDo('my todo');
  // ...
});

Configure the option in config file.

playwright.config.ts
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!' },
    },
  ]
});

Learn more about fixtures and parametrizing tests.

Arguments

Returns

test.fail​

Added in: v1.10 test.test.fail

Marks 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.

  • condition boolean (optional)#

    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.fail.only​

Added in: v1.49 test.test.fail.only

You can use test.fail.only to focus on a specific test that is expected to fail. This is particularly useful when debugging a failing test or working on a specific issue.

To declare a focused "failing" test:

  • test.fail.only(title, body)
  • test.fail.only(title, details, body)

Usage

You can declare a focused failing test, so that Playwright runs only this test and ensures it actually fails.

import { test, expect } from '@playwright/test';

test.fail.only('focused failing test', async ({ page }) => {
  // This test is expected to fail
});
test('not in the focused group', async ({ page }) => {
  // This test will not run
});

Arguments

test.fixme​

Added in: v1.10 test.test.fixme

Mark 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.

import { test, expect } from '@playwright/test';

test('less readable', async ({ page }) => {
  test.fixme();
  // ...
});

Arguments

  • title string (optional)#

    Test title.

  • details Object (optional) Added in: v1.42#

  • body function(Fixtures, TestInfo) (optional)#

    Test body that takes one or two arguments: an object with fixtures and optional TestInfo.

  • condition boolean (optional)#

    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.info​

Added in: v1.10 test.test.info

Returns information about the currently running test. This method can only be called during the test execution, otherwise it throws.

Usage

test('example test', async ({ page }) => {
  // ...
  await test.info().attach('screenshot', {
    body: await page.screenshot(),
    contentType: 'image/png',
  });
});

Returns

test.only​

Added in: v1.10 test.test.only

Declares a focused test. If there are some focused tests or suites, all of them will be run but nothing else.

  • test.only(title, body)
  • test.only(title, details, body)

Usage

test.only('focus this test', async ({ page }) => {
  // Run only focused tests in the entire project.
});

Arguments

test.setTimeout​

Added in: v1.10 test.test.setTimeout

Changes the timeout for the test. Zero means no timeout. Learn more about various timeouts.

Timeout for the currently running test is available through testInfo.timeout.

Usage

  • Changing test timeout.

    test('very slow test', async ({ page }) => {
      test.setTimeout(120000);
      // ...
    });

  • Changing timeout from a slow beforeEach hook. Note that this affects the test timeout that is shared with beforeEach 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 or afterAll hook. Note this affects the hook's timeout, not the test timeout.

    test.beforeAll(async () => {
      // Set timeout for this hook.
      test.setTimeout(60000);
    });

  • Changing timeout for all tests in a test.describe() group.

    test.describe('group', () => {
      // Applies to all tests in this group.
      test.describe.configure({ timeout: 60000 });

      test('test one', async () => { /* ... */ });
      test('test two', async () => { /* ... */ });
      test('test three', async () => { /* ... */ });
    });

Arguments

  • timeout number#

    Timeout in milliseconds.

test.skip​

Added in: v1.10 test.test.skip

Skip 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.

To declare a skipped test:

  • test.skip(title, body)
  • test.skip(title, details, body)

To skip a test at runtime:

  • test.skip(condition, description)
  • test.skip(callback, description)
  • test.skip()

Usage

You can declare a skipped test, and Playwright will not run it.

import { test, expect } from '@playwright/test';

test.skip('never run', async ({ page }) => {
  // ...
});

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 skip all tests in a file or test.describe() group based on some condition with a single test.skip(callback, description) call.

import { test, expect } from '@playwright/test';

test.skip(({ browserName }) => browserName !== 'webkit', 'Safari-only');

test('Safari-only test 1', async ({ page }) => {
  // ...
});
test('Safari-only test 2', async ({ page }) => {
  // ...
});

You can also call test.skip() without arguments inside the test body to always mark the test as failed. We recommend using test.skip(title, body) instead.

import { test, expect } from '@playwright/test';

test('less readable', async ({ page }) => {
  test.skip();
  // ...
});

Arguments

  • title string (optional)#

    Test title.

    Optional description that will be reflected in a test report.

test.slow​

Added in: v1.10 test.test.slow

Marks a test as "slow". Slow test will be given triple the default timeout.

Note that test.slow() cannot be used in a beforeAll or afterAll hook. Use test.setTimeout() instead.

  • test.slow()
  • test.slow(condition, description)
  • test.slow(callback, description)

Usage

You can mark a test as slow by calling test.slow() inside the test body.

import { test, expect } from '@playwright/test';

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

If your test is slow in some configurations, but not all, you can mark it as slow based on a condition. We recommend passing a description argument in this case.

import { test, expect } from '@playwright/test';

test('slow in Safari', async ({ page, browserName }) => {
  test.slow(browserName === 'webkit', 'This feature is slow in Safari');
  // ...
});

You can mark all tests in a file or test.describe() group as "slow" based on some condition by passing a callback.

import { test, expect } from '@playwright/test';

test.slow(({ browserName }) => browserName === 'webkit', 'all tests are slow in Safari');

test('slow in Safari 1', async ({ page }) => {
  // ...
});

  });

  await test.step('Outer step', async () => {
    // ...
    // You can nest steps inside each other.
    await test.step('Inner step', async () => {
      // ...
    });
  });
});

Arguments

Details

The method returns the value returned by the step callback.

import { test, expect } from '@playwright/test';

test('test', async ({ page }) => {
  const user = await test.step('Log in', async () => {
    // ...
    return 'john';
  });
  expect(user).toBe('john');
});

Decorator

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: v1.10 test.test.use

Specifies 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

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: v1.10 test.test.expect

expect 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: v1.10 test.test.describe.parallel
Discouraged

See 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

test.describe.parallel.only​

Added in: v1.10 test.test.describe.parallel.only
Discouraged

See 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

test.describe.serial​

Added in: v1.10 test.test.describe.serial
Discouraged

See 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.

note

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

  • test.describe.serial.only(title, callback)
  • test.describe.serial.only(title)
  • test.describe.serial.only(title, details, callback)

Usage

test.describe.serial.only('group', () => {
  test('runs first', async ({ page }) => {
  });
  test('runs second', async ({ page }) => {
  });
});

You can also omit the title.

test.describe.serial.only(() => {
  // ...
});
