What's Web Automation Libraries?

Web automation libraries are tools designed to facilitate the automation of web browser interactions, enabling developers to simulate user actions, scrape data, test web applications, and more. These libraries provide APIs that allow for programmatic control over web browsers, making it easier to perform repetitive tasks, conduct automated testing, and gather data from web pages. Each library has its own strengths, weaknesses, and use cases, making it essential for developers to choose the right tool based on their specific requirements and project goals.

Feature Comparison: playwright vs puppeteer vs selenium-webdriver vs nightmare

Browser Support

  • playwright: Playwright supports multiple browsers including Chromium, Firefox, and WebKit. This allows for comprehensive testing across different environments and ensures compatibility with various web standards.
  • puppeteer: Puppeteer is designed specifically for Chrome and Chromium. While it can be used for headless browsing, its focus on a single browser may limit its applicability in cross-browser scenarios.
  • selenium-webdriver: Selenium WebDriver supports a wide range of browsers including Chrome, Firefox, Safari, and Internet Explorer. This makes it an excellent choice for projects that require extensive cross-browser testing.
  • nightmare: Nightmare primarily supports Electron, which is based on Chromium. This makes it suitable for applications built with web technologies but limits its use for testing across different browsers.

Ease of Use

  • playwright: Playwright offers a rich API with advanced features, but it may have a steeper learning curve compared to simpler libraries. However, its powerful capabilities justify the investment in learning.

Feature Set

  • playwright: Playwright provides a comprehensive feature set, including auto-waiting, intercepting network requests, and handling multiple browser contexts. It is designed for modern web applications with complex interactions.
  • puppeteer: Puppeteer excels in generating screenshots, PDFs, and scraping content. It offers a rich set of features for working with Chrome, making it ideal for content-heavy applications.
  • selenium-webdriver: Selenium WebDriver offers a broad range of features for browser automation, including support for various programming languages and extensive capabilities for testing web applications across multiple browsers.
  • nightmare: Nightmare offers basic automation features such as navigation, form submission, and screenshot capabilities. It is suitable for simple tasks but lacks advanced features found in other libraries.
How to Choose: playwright vs puppeteer vs selenium-webdriver vs nightmare
  • playwright: Choose Playwright if you require support for multiple browser contexts and want to run tests in parallel across different browsers. It offers advanced features like auto-waiting and is ideal for modern web applications that require comprehensive testing across various environments.
  • puppeteer: Choose Puppeteer if you are focused on Google Chrome or Chromium and need a powerful tool for headless browser automation. Puppeteer excels in generating screenshots, PDFs, and scraping content, making it a great choice for projects heavily reliant on these features.
  • selenium-webdriver: Choose Selenium WebDriver if you need a robust and widely adopted solution for cross-browser testing. It supports multiple programming languages and browsers, making it suitable for large-scale testing frameworks and enterprise applications.
  • nightmare: Choose Nightmare if you need a simple and lightweight solution for web scraping or testing that requires minimal setup and is easy to use. It's particularly suited for smaller projects or quick automation tasks.

Documentation | API reference

Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast.

Installation

Playwright has its own test runner for end-to-end tests, we call it Playwright Test.

Using init command

The easiest way to get started with Playwright Test is to run the init command.

# Run from your project's root directory
npm init playwright@latest
# Or create a new project
npm init playwright@latest new-project

This will create a configuration file, optionally add examples, a GitHub Action workflow and a first test example.spec.ts. You can now jump directly to writing assertions section.

Manually

Add dependency and install browsers.

npm i -D @playwright/test
# install supported browsers
npx playwright install

You can optionally install only selected browsers, see install browsers for more details. Or you can install no browsers at all and use existing browser channels.

Capabilities

Resilient • No flaky tests

Auto-wait. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - a primary cause of flaky tests.

Web-first assertions. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met.

Tracing. Configure test retry strategy, capture execution trace, videos and screenshots to eliminate flakes.

No trade-offs • No limits

Browsers run web content belonging to different origins in different processes. Playwright is aligned with the architecture of the modern browsers and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.

Multiple everything. Test scenarios that span multiple tabs, multiple origins and multiple users. Create scenarios with different contexts for different users and run them against your server, all in one test.

Trusted events. Hover elements, interact with dynamic controls and produce trusted events. Playwright uses real browser input pipeline indistinguishable from the real user.

Test frames, pierce Shadow DOM. Playwright selectors pierce shadow DOM and allow entering frames seamlessly.

Full isolation • Fast execution

Browser contexts. Playwright creates a browser context for each test. Browser context is equivalent to a brand new browser profile. This delivers full test isolation with zero overhead. Creating a new browser context only takes a handful of milliseconds.

Log in once. Save the authentication state of the context and reuse it in all the tests. This bypasses repetitive log-in operations in each test, yet delivers full isolation of independent tests.

Powerful Tooling

Codegen. Generate tests by recording your actions. Save them into any language.

Playwright inspector. Inspect page, generate selectors, step through the test execution, see click points and explore execution logs.

Trace Viewer. Capture all the information to investigate the test failure. Playwright trace contains test execution screencast, live DOM snapshots, action explorer, test source and many more.

Page screenshot

This code snippet navigates to Playwright homepage and saves a screenshot.

import { test } from '@playwright/test';

test('Page Screenshot', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  await page.screenshot({ path: `example.png` });
});

Mobile and geolocation

This snippet emulates Mobile Safari on a device at given geolocation, navigates to maps.google.com, performs the action and takes a screenshot.

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

test.use({
  ...devices['iPhone 13 Pro'],
  locale: 'en-US',
  geolocation: { longitude: 12.492507, latitude: 41.889938 },
  permissions: ['geolocation'],
})

test('Mobile and geolocation', async ({ page }) => {
  await page.goto('https://maps.google.com');
  await page.getByText('Your location').click();
  await page.waitForRequest(/.*preview\/pwa/);
  await page.screenshot({ path: 'colosseum-iphone.png' });
});

Evaluate in browser context

This code snippet navigates to example.com, and executes a script in the page context.

import { test } from '@playwright/test';

test('Evaluate in browser context', async ({ page }) => {
  await page.goto('https://www.example.com/');
  const dimensions = await page.evaluate(() => {
    return {
      width: document.documentElement.clientWidth,
      height: document.documentElement.clientHeight,
      deviceScaleFactor: window.devicePixelRatio
    }
  });
  console.log(dimensions);
});

Intercept network requests

This code snippet sets up request routing for a page to log all network requests.

import { test } from '@playwright/test';

test('Intercept network requests', async ({ page }) => {
  // Log and continue all network requests
  await page.route('**', route => {
    console.log(route.request().url());
    route.continue();
  });
  await page.goto('http://todomvc.com');
});
