Configuring playwright.config.ts
The playwright.config.ts file in Playwright is the heart of your test setup. It allows you to define global settings for test execution, making automation flexible and maintainable. Instead of repeating options in every test, you can configure them once and reuse across the project.
The file typically begins with importing defineConfig from Playwright Test. Inside, you set test directory, timeout values, and reporters like list, html, or allure. You can also define whether tests should run in headless mode or show the browser for debugging.
One of the most powerful features is projects. Projects let you configure multiple browsers (Chromium, Firefox, WebKit) or different viewports (desktop, mobile). This way, the same test suite can validate your application across platforms.
You can also add global setup and teardown, specify baseURL to avoid hardcoding links, and enable traces, videos, or screenshots for debugging failures. For CI/CD, options like retries and parallel execution can be defined to stabilize tests.
Example snippet:
import { defineConfig } from '@playwright/test';
export default defineConfig({
timeout: 30000,
use: {
headless: true,
baseURL: 'https://example.com',
screenshot: 'only-on-failure',
},
projects: [
{ name: 'chromium', use: { browserName: 'chromium' } },
{ name: 'firefox', use: { browserName: 'firefox' } },
],
});
