Playwright Configuration File

Playwright is a powerful automation framework for end-to-end testing of web applications. Instead of configuring settings manually in every test file, Playwright provides a central configuration file, playwright.config.ts, where you can define global settings such as browser settings, timeouts, and test configurations.

Understanding `playwright.config.ts`

The playwright.config.ts file is the main configuration file for Playwright tests. It helps set up global configurations that apply to all tests, reducing the need for repetitive settings in individual test files. This file is written in TypeScript or JavaScript.

Here’s a basic example of a playwright.config.ts file:


 import { defineConfig } from '@playwright/test';
 
 export default defineConfig({
 timeout: 60000, // Global timeout for all tests (60 seconds)
 use: {
 headless: true, // Run tests in headless mode
 viewport: { width: 1280, height: 720 }, // Default viewport size
 actionTimeout: 5000, // Timeout for individual actions (5 seconds)
 },
 });

Configuring Browsers for Projects

Playwright supports multiple browsers, including Chromium, Firefox, and WebKit. You can configure which browsers to use in the configuration file.

Example of configuring multiple browsers:


 export default defineConfig({
 projects: [
 {
 name: 'chromium',
 use: { browserName: 'chromium' },
 },
 {
 name: 'firefox',
 use: { browserName: 'firefox' },
 },
 {
 name: 'webkit',
 use: { browserName: 'webkit' },
 },
 ],
 });

In the configuration projects section, Playwright is configured to run on the three browsers (chromium, firefox, webkit). When executing a Playwright test, it will run on all three browsers.

Running Tests with the Configuration

Let’s see how to run the tests with the configuration specified in the file. After defining your configuration, you can execute your tests using the Playwright test runner:
