# class: TestOptions
* since: v1.10
* 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
import { defineConfig } from '@playwright/test';
export default defineConfig({
  use: {
    headless: false,
    viewport: { width: 1280, height: 720 },
    ignoreHTTPSErrors: true,
    video: 'on-first-retry',
  },
});
```

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

```js
// 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
* since: v1.10
- type: <[BrowserName]<"chromium"|"firefox"|"webkit">>

Name of the browser that runs tests. Defaults to `'chromium'`. Most of the time you should set `browserName` in your [TestConfig]:

```js
// playwright.config.ts
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  use: {
    browserName: 'firefox',
  },
});
```

## property: TestOptions.actionTimeout
* since: v1.10
- type: <[int]>

Default timeout for each Playwright action in milliseconds, defaults to 0 (no timeout).

This is a default timeout for all Playwright actions, same as configured via [`method: Page.setDefaultTimeout`].

If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page will be scaled down if necessary to fit the specified size.
