Playwright can either be used as a part of the Playwright Test test runner (this guide), or as a [Playwright Library](./library.md).

Playwright Test was created specifically to accommodate the needs of the end-to-end testing. It does everything you would expect from the regular test runner, and more. Playwright test allows to:

- Run tests across all browsers.
- Execute tests in parallel.
- Enjoy context isolation out of the box.
- Capture videos, screenshots and other artifacts on failure.
- Integrate your POMs as extensible fixtures.

## Installation

Playwright has its own test runner for end-to-end tests, we call it Playwright Test.

### Using init command

The easiest way to get started with Playwright Test is to run the init command.

```bash
# Run from your project's root directory
npm init playwright
# Or create a new project
npm init playwright new-project
```

This will create a configuration file, optionally add examples, a GitHub Action workflow and a first test `example.spec.ts`. You can now jump directly to [writing assertions](#writing-assertions) section.

### Manually

Add dependency and install browsers.

```bash
npm i -D @playwright/test
# install supported browsers
npx playwright install
```

You can optionally install only selected browsers, see [install browsers](./cli.md#install-browsers) for more details. Or you can install no browsers at all and use existing [browser channels](./browsers.md).

## First test

Create `tests/example.spec.js` (or `tests/example.spec.ts` for TypeScript) to define your test.

```js js-flavor=js
const { test, expect } = require('@playwright/test');

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  const title = page.locator('.navbar__inner .navbar__title');
  await expect(title).toHaveText('Playwright');
});
```

```js js-flavor=ts
import { test, expect } from '@playwright/test';

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  const title = page.locator('.navbar__inner .navbar__title');
  await expect(title).toHaveText('Playwright');
});
```

Now run your tests, assuming that test files are in the `tests` directory.

```bash
npx playwright test
```

Playwright Test just ran a test using Chromium browser, in a headless manner. Let's tell it to use headed browser:

```bash
npx playwright test --headed
```

## Configuration file

To enjoy all the features that Playwright Test has to offer, you would want to create a configuration file `playwright.config.ts` (or `playwright.config.js`). It allows you to run tests in multiple browsers configured as you'd like.

Here is an example configuration that runs every test in Chromium, Firefox and WebKit, by creating a "project" for each browser configuration. It also specifies [two retries](./test-retries.md) and [tracing](./trace-viewer.md) options.

```js js-flavor=js
// playwright.config.js
// @ts-check
const { devices } = require('@playwright/test');

/** @type {import('@playwright/test').PlaywrightTestConfig} */
const config = {
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  use: {
    trace: 'on-first-retry',
  },
  projects: [
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'] },
    },
    {
      name: 'firefox',
      use: { ...devices['Desktop Firefox'] },
    },
    {
      name: 'webkit',
      use: { ...devices['Desktop Safari'] },
    },
  ],
};

module.exports = config;
```

```js js-flavor=ts
// playwright.config.ts
import { PlaywrightTestConfig, devices } from '@playwright/test';

const config: PlaywrightTestConfig = {
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  use: {
    trace: 'on-first-retry',
  },
  projects: [
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'] },
    },
    {
      name: 'firefox',
      use: { ...devices['Desktop Firefox'] },
    },
    {
      name: 'webkit',
      use: { ...devices['Desktop Safari'] },
    },
  ],
};
export default config;
```

Look for more options in the [configuration section](./test-configuration.md).

Now you can run tests in multiple browsers by default.

```bash
npx playwright test

Running 5 tests using 5 workers

  ✓ [chromium] › example.spec.ts:3:1 › basic test (2s)
  ✓ [firefox] › example.spec.ts:3:1 › basic test (2s)
  ✓ [webkit] › example.spec.ts:3:1 › basic test (2s)
```

Use `--project` command line option to run a single project.

```bash
npx playwright test --project=firefox

Running 1 test using 1 worker

  ✓ [firefox] › example.spec.ts:3:1 › basic test (2s)
```

## Writing assertions

Playwright Test uses [expect](https://jestjs.io/docs/expect) library for test assertions. It extends it with the Playwright-specific matchers to achieve greater testing ergonomics.

Learn more about [test assertions here](./test-assertions.md).

Here is a quick example of using them:


```js js-flavor=js
// example.spec.js
const { test, expect } = require('@playwright/test');

test('my test', async ({ page }) => {
  await page.goto('https://playwright.dev/');

  // Expect a title "to contain" a substring.
  await expect(page).toHaveTitle(/Playwright/);

  // Expect an attribute "to be strictly equal" to the value.
  await expect(page.locator('text=Get Started').first()).toHaveAttribute('href', '/docs/intro');

  await page.click('text=Get Started');
  // Expect some text to be visible on the page.
  await expect(page.locator('text=Introduction').first()).toBeVisible();
});
```

```js js-flavor=ts
// example.spec.ts
import { test, expect } from '@playwright/test';

test('my test', async ({ page }) => {
  await page.goto('https://playwright.dev/');

  // Expect a title "to contain" a substring.
  await expect(page).toHaveTitle(/Playwright/);

  // Expect an attribute "to be strictly equal" to the value.
  await expect(page.locator('text=Get Started').first()).toHaveAttribute('href', '/docs/intro');

  await page.click('text=Get Started');
  // Expect some text to be visible on the page.
  await expect(page.locator('text=Introduction').first()).toBeVisible();
});
```

## Using test fixtures

You noticed an argument `{ page }` that the test above has access to:

```js js-flavor=js
test('basic test', async ({ page }) => {
  ...
```

```js js-flavor=ts
test('basic test', async ({ page }) => {
  ...
```

We call these arguments `fixtures`. Fixtures are objects that are created for each test run. Playwright Test comes loaded with those fixtures, and you can add your own fixtures as well. When running tests, Playwright Test looks at each test declaration, analyses the set of fixtures the test needs and prepares those fixtures specifically for the test.

Here is a list of the pre-defined fixtures that you are likely to use most of the time:

|Fixture    |Type             |Description                      |
|:----------|:----------------|:--------------------------------|
|page       |[Page]           |Isolated page for this test run. |
|context    |[BrowserContext] |Isolated context for this test run. The `page` fixture belongs to this context as well. Learn how to [configure context](./test-configuration.md). |
|browser    |[Browser]        |Browsers are shared across tests to optimize resources. Learn how to [configure browser](./test-configuration.md). |
|browserName|[string]         |The name of the browser currently running the test. Either `chromium`, `firefox` or `webkit`.|

## Using test hooks

You can use `test.beforeAll` and `test.afterAll` hooks to set up and tear down resources shared between tests.
And you can use `test.beforeEach` and `test.afterEach` hooks to set up and tear down resources for each test individually.

```js js-flavor=js
// example.spec.js
const { test, expect } = require('@playwright/test');

test.describe('feature foo', () => {
  test.beforeEach(async ({ page }) => {
    // Go to the starting url before each test.
    await page.goto('https://playwright.dev/');
  });

  test('my test', async ({ page }) => {
    // Assertions use the expect API.
    await expect(page).toHaveURL('https://playwright.dev/');
  });
});
```

```js js-flavor=ts
// example.spec.ts
import { test, expect } from '@playwright/test';

test.describe('feature foo', () => {
  test.beforeEach(async ({ page }) => {
    // Go to the starting url before each test.
    await page.goto('https://playwright.dev/');
  });

  test('my test', async ({ page }) => {
    // Assertions use the expect API.
    await expect(page).toHaveURL('https://playwright.dev/');
  });
});
```


## Command line

Following are the usual command line patterns. Learn more about the [command line](./test-cli.md).

- Run all the tests
  ```bash
  npx playwright test
  ```

- Run a single test file
  ```bash
  npx playwright test tests/todo-page.spec.ts
  ```

- Run a set of test files
  ```bash
  npx playwright test tests/todo-page/ tests/landing-page/
  ```

- Run files that have `my-spec` or `my-spec-2` in the file name
  ```bash
  npx playwright test my-spec my-spec-2
  ```

- Run the test with the title
  ```bash
  npx playwright test -g "add a todo item"
  ```

- Run tests in headed browsers
  ```bash
  npx playwright test --headed
  ```

- Run tests in a particular configuration (project)
  ```bash
  npx playwright test --project=firefox
  ```

- Disable [parallelization](./test-parallel.md)
  ```bash
  npx playwright test --workers=1
  ```

- Choose a [reporter](./test-reporters.md)
  ```bash
  npx playwright test --reporter=dot
  ```

- Run in debug mode with [Playwright Inspector](./inspector.md)
  ```bash
  npx playwright test --debug
  ```

- Ask for help
  ```bash
  npx playwright test --help
  ```

## Configure NPM scripts

Playwright Test will automatically pick up `playwright.config.js` or `playwright.config.ts`.

```json
{
  "scripts": {
    "test": "playwright test"
  }
}
```

If you put your configuration file in a different place, pass it with `--config` option.

```json
{
  "scripts": {
    "test": "playwright test --config=tests/example.config.js"
  }
}
```

:::note
  To pass options through npm script, use double dashes: ```npm run test -- --headed```.
