TestOptions

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

These options are usually provided in the configuration file through testConfig.use and testProject.use.

playwright.config.ts
import { defineConfig } from '@playwright/test';
export default defineConfig({
  use: {
    headless: false,
    viewport: { width: 1280, height: 720 },
    ignoreHTTPSErrors: true,
    video: 'on-first-retry',
  },
});

Alternatively, with test.use() you can override some options for a file.

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 }) => {
  // ...
});

Properties​

acceptDownloads​

Added in: v1.10 testOptions.acceptDownloads

Usage

playwright.config.ts
import { defineConfig } from '@playwright/test';

export default defineConfig({

    acceptDownloads: false,
  },
});

Type

actionTimeout​

Added in: v1.10 testOptions.actionTimeout

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 page.setDefaultTimeout().

Type

baseURL​

Added in: v1.10 testOptions.baseURL

  • baseURL: http://localhost:3000/foo/ and navigating to ./bar.html results in http://localhost:3000/foo/bar.html
  • baseURL: http://localhost:3000/foo (without trailing slash) and navigating to ./bar.html results in http://localhost:3000/bar.html

Usage

import { defineConfig, devices } from '@playwright/test';

export default defineConfig({

    /* Base URL to use in actions like `await page.goto('/')`. */
