Playwright vs Cypress. Quick Overview

Playwright vs Cypress. Quick Overview
March 13, 2023 by Kate Savelova

When it comes to testing web applications, there are various frameworks available in the market, with different features and capabilities. Two such popular frameworks are Playwright and Cypress. While both of them are designed to perform end-to-end testing of web applications, there are significant differences between the two. In this article, we will explore these differences and help you choose the right framework for your testing needs.

Overview

Playwright and Cypress are both open-source end-to-end testing frameworks, but they differ in terms of their architecture, features, and ease of use.

Playwright

Playwright is a relatively new framework developed by Microsoft. It supports multiple browsers, including Chrome, Firefox, Safari, and Edge. Playwright is designed to automate browser actions, such as clicking on buttons, filling forms, and navigating between pages, in a way that is simple and easy to use.

One of the key features of Playwright is its ability to automate headless browsers, which means that it can run tests without opening a visible browser window. This makes it an ideal choice for continuous integration (CI) and deployment (CD) pipelines, as well as for testing applications on remote servers.

Another advantage of Playwright is its cross-platform compatibility. It works on Windows, macOS, and Linux, making it a versatile framework that can be used in different environments.

const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  await page.goto('https://www.google.com');
  await page.type('input[name="q"]', 'Playwright vs Cypress');
  await page.keyboard.press('Enter');
  await page.waitForSelector('div#search');
  const searchResults = await page.$$eval('div.g', (results) => {
    return results.map((result) => {
      const titleElement = result.querySelector('h3');
      const linkElement = result.querySelector('a');
      return {
        title: titleElement.innerText,
        link: linkElement.href,
      };
    });
  });
  console.log(searchResults);
  await browser.close();
})();

In this example, we’re using Playwright to launch a Chromium browser, navigate to Google, search for “Playwright vs Cypress,” and scrape the search results. Notice how we’re able to use Playwright’s API to interact with the browser in a very granular way.

Cypress

Cypress, on the other hand, is a JavaScript-based testing framework that is focused on end-to-end testing. It supports only one browser, Chrome, and is designed to run tests in a single browser window. This means that it is not suitable for headless testing, and is primarily used for testing user interfaces.

One of the key features of Cypress is its ability to automatically reload the browser window as you write your tests. This makes it easy to see the results of your changes in real-time, without having to run the tests again.

Cypress also has a built-in dashboard that provides insights into test runs, including screenshots, videos, and error messages. This makes it easy to identify and fix issues in your application.

describe('Google search', () => {
  it('searches for "Playwright vs Cypress"', () => {
    cy.visit('https://www.google.com');
    cy.get('input[name="q"]').type('Playwright vs Cypress{enter}');
    cy.get('div#search').should('be.visible');
    cy.get('div.g').should('have.length.greaterThan', 0).then((results) => {
      const searchResults = results.toArray().map((result) => {
        const titleElement = result.querySelector('h3');
        const linkElement = result.querySelector('a');
        return {
          title: titleElement.innerText,
          link: linkElement.href,
        };
      });
      console.log(searchResults);
    });
  });
});

In this example, we’re using Cypress to test a Google search for “Playwright vs Cypress.” Notice how we’re able to use Cypress’s API to interact with the DOM in a very intuitive way, and how Cypress’s built-in test runner allows us to see our tests in action as we write them.

Differences

The main differences between Playwright and Cypress can be summarized as follows:

1. Architecture

Playwright is designed to automate browser actions, while Cypress is designed to test user interfaces. Playwright supports multiple browsers and can run tests in headless mode, while Cypress supports only Chrome and runs tests in a visible browser window.

2. Ease of use

Playwright is relatively easy to use, with a simple API and a cross-platform CLI tool. Cypress, on the other hand, has a steeper learning curve, with a more complex API and a specific way of organizing tests.

3. Integration

Playwright integrates easily with CI/CD pipelines and can be used in different environments. Cypress, on the other hand, is tightly integrated with Chrome and requires a specific setup to work in other environments.

4. Browser support

Playwright supports multiple browsers, including Chrome, Firefox, Safari, and Edge, while Cypress supports only Chrome.

5. Community

Both Playwright and Cypress have active communities that provide support and guidance for users. However, Cypress has been around longer and has a larger community, which means there is more support available for users.

In summary, Playwright and Cypress are both excellent choices for testing web applications, but they have different strengths and weaknesses. If you need to test your application in multiple browsers and want a more low-level API, Playwright may be the better choice for you. If you’re focused on testing in Chrome and want an easy-to-use API, Cypress may be the better option.

Ultimately, the choice between Playwright and Cypress depends on your specific needs and preferences. Both frameworks offer excellent functionality and can help you build more reliable and robust web applications.
