# class: TestOptions
* langs: js

Playwright Test provides many options to configure test environment, [Browser], [BrowserContext] and more.

These options are usually provided in the [configuration file](./test-configuration.md) through [`property: TestConfig.use`] and [`property: TestProject.use`].

```js js-flavor=js
// @ts-check

/** @type {import('@playwright/test').PlaywrightTestConfig} */
const config = {
  use: {
    headless: false,
    viewport: { width: 1280, height: 720 },
    ignoreHTTPSErrors: true,
    video: 'on-first-retry',
  },
};

module.exports = config;
```

```js js-flavor=ts
import { PlaywrightTestConfig } from '@playwright/test';
const config: PlaywrightTestConfig = {
  use: {
    headless: false,
    viewport: { width: 1280, height: 720 },
    ignoreHTTPSErrors: true,
    video: 'on-first-retry',
  },
};
export default config;
```

Alternatively, with [`method: Test.use`] you can override some options for a file.

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

// Run tests in this file with portrait-like viewport.
test.use({ viewport: { width: 600, height: 900 } });

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

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

// Run tests in this file with portrait-like viewport.
test.use({ viewport: { width: 600, height: 900 } });

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

## property: TestOptions.browserName
- type: <[BrowserName]<"chromium"|"firefox"|"webkit">>

const config = {
  use: {
    browserName: 'firefox',
  },
};

module.exports = config;
```

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

const config: PlaywrightTestConfig = {
  use: {
    browserName: 'firefox',
  },
};
export default config;
```
