## Version 1.14

### 🎭 Playwright Library

#### ⚡️ New "strict" mode

Selector ambiguity is a common problem in automation testing. **"strict" mode**
ensures that your selector points to a single element and throws otherwise.

Pass `strict: true` into your action calls to opt in.

```js
// This will throw if you have more than one button!
await page.click('button', { strict: true });
```

#### 📍 New [**Locators API**](./api/class-locator)

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the [Locator](./api/class-locator) and [ElementHandle](./api/class-elementhandle) is that the latter points to a particular element, while [Locator](./api/class-locator) captures the logic of how to retrieve that element.

Also, locators are **"strict" by default**!

```js
const locator = page.locator('button');
await locator.click();
```

Learn more in the [documentation](./api/class-locator).

#### 🧩 Experimental [**React**](./selectors#react-selectors) and [**Vue**](./selectors#vue-selectors) selector engines

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to [attribute selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors) and supports all attribute selector operators.

```js
await page.click('_react=SubmitButton[enabled=true]');
await page.click('_vue=submit-button[enabled=true]');
```

Learn more in the [react selectors documentation](./selectors#react-selectors) and the [vue selectors documentation](./selectors#vue-selectors).

#### ✨ New [**`nth`**](./selectors#n-th-element-selector) and [**`visible`**](./selectors#selecting-visible-elements) selector engines

- [`nth`](./selectors#n-th-element-selector) selector engine is equivalent to the `:nth-match` pseudo class, but could be combined with other selector engines.
- [`visible`](./selectors#selecting-visible-elements) selector engine is equivalent to the `:visible` pseudo class, but could be combined with other selector engines.

```js
// select the first button among all buttons
await button.click('button >> nth=0');
// or if you are using locators, you can use first(), nth() and last()
await page.locator('button').first().click();

// click a visible button
await button.click('button >> visible=true');
```

### 🎭 Playwright Test

#### ✅ Web-First Assertions

`expect` now supports lots of new web-first assertions.

Consider the following example:

```js
await expect(page.locator('.status')).toHaveText('Submitted');
```

Playwright Test will be re-testing the node with the selector `.status` until fetched Node has the `"Submitted"` text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can either pass this timeout or configure it once via the [`testProject.expect`](./api/class-testproject/#test-project-expect) value in test config.

By default, the timeout for assertions is not set, so it'll wait forever, until the whole test times out.

List of all new assertions:

- [`expect(locator).toBeChecked()`](./test-assertions#expectlocatortobechecked)
- [`expect(locator).toBeDisabled()`](./test-assertions#expectlocatortobedisabled)
- [`expect(locator).toBeEditable()`](./test-assertions#expectlocatortobeeditable)
- [`expect(locator).toBeEmpty()`](./test-assertions#expectlocatortobeempty)
- [`expect(locator).toBeEnabled()`](./test-assertions#expectlocatortobeenabled)
- [`expect(locator).toBeFocused()`](./test-assertions#expectlocatortobefocused)
- [`expect(locator).toBeHidden()`](./test-assertions#expectlocatortobehidden)
- [`expect(locator).toBeVisible()`](./test-assertions#expectlocatortobevisible)
- [`expect(locator).toContainText(text, options?)`](./test-assertions#expectlocatortocontaintexttext-options)
- [`expect(locator).toHaveAttribute(name, value)`](./test-assertions#expectlocatortohaveattributename-value)
- [`expect(locator).toHaveClass(expected)`](./test-assertions#expectlocatortohaveclassexpected)
- [`expect(locator).toHaveCount(count)`](./test-assertions#expectlocatortohavecountcount)
- [`expect(locator).toHaveCSS(name, value)`](./test-assertions#expectlocatortohavecssname-value)
- [`expect(locator).toHaveId(id)`](./test-assertions#expectlocatortohaveidid)
- [`expect(locator).toHaveJSProperty(name, value)`](./test-assertions#expectlocatortohavejspropertyname-value)
- [`expect(locator).toHaveText(expected, options)`](./test-assertions#expectlocatortohavetextexpected-options)
- [`expect(page).toHaveTitle(title)`](./test-assertions#expectpagetohavetitletitle)
- [`expect(page).toHaveURL(url)`](./test-assertions#expectpagetohaveurlurl)
- [`expect(locator).toHaveValue(value)`](./test-assertions#expectlocatortohavevaluevalue)

#### ⛓ Serial mode with [`describe.serial`](./api/class-test#test-describe-serial)

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.

```ts
test.describe.serial('group', () => {
  test('runs first', async ({ page }) => { /* ... */ });
  test('runs second', async ({ page }) => { /* ... */ });
});
```

Learn more in the [documentation](./api/class-test#test-describe-serial).

#### 🐾 Steps API with [`test.step`](./api/class-test#test-step)

Split long tests into multiple steps using `test.step()` API:

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

test('test', async ({ page }) => {
  await test.step('Log in', async () => {
    // ...
  });
  await test.step('news feed', async () => {
    // ...
  });
});
```

Step information is exposed in reporters API.

#### 🌎 Launch web server before running tests

To launch a server during the tests, use the [`webServer`](./test-advanced/#launching-a-development-web-server-during-the-tests) option in the configuration file. The server will wait for a given port to be available before running the tests, and the port will be passed over to Playwright as a [`baseURL`](./api/class-fixtures#fixtures-base-url) when creating a context.

```ts
// playwright.config.ts
import { PlaywrightTestConfig } from '@playwright/test';
const config: PlaywrightTestConfig = {
  webServer: {
    command: 'npm run start', // command to launch
    port: 3000, // port to await for 
    timeout: 120 * 1000, 
    reuseExistingServer: !process.env.CI,
  },
};
export default config;
```

## Version 1.12

#### ⚡️ Introducing Playwright Test

[Playwright Test](./intro.md) is a **new test runner** built from scratch by Playwright team specifically to accommodate end-to-end testing needs:

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

Installation:
```bash
npm i -D @playwright/test
```

Simple test `tests/foo.spec.ts`:

```ts
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');
});
```

Running:

```bash
npx playwright test
```

👉  Read more in [Playwright Test documentation](./intro.md).

#### 🧟‍♂️ Introducing Playwright Trace Viewer

[Playwright Trace Viewer](./trace-viewer.md) is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:
- page DOM before and after each Playwright action
- page rendering before and after each Playwright action
- browser network during script execution

Traces are recorded using the new [`property: BrowserContext.tracing`] API:

```ts
const browser = await chromium.launch();
const context = await browser.newContext();

// Start tracing before creating / navigating a page.
await context.tracing.start({ screenshots: true, snapshots: true });

const page = await context.newPage();
await page.goto('https://playwright.dev');

// Stop tracing and export it into a zip archive.
await context.tracing.stop({ path: 'trace.zip' });
```

Traces are examined later with the Playwright CLI:


```sh
npx playwright show-trace trace.zip
```

That will open the following GUI:
