Playwright vs Cypress: Core Differences

Popular end-to-end testing frameworks like Playwright and Cypress allow developers to create and run tests for online applications. Both frameworks have certain commonalities, but they also ‌vary in terms of architecture and testing strategies.

The key distinctions between Playwright and Cypress are as follows:

Architecture

A Node.js module called Playwright offers a high-level API for managing web browsers. It may be used with many other programming languages, including Java, Python, TypeScript, and JavaScript. Playwright can perform tests in a variety of browsers since it connects to Chromium, Firefox, and WebKit using the DevTools protocol.

On the other side, Cypress is a testing framework that runs entirely within the browser and is based on JavaScript. Because it is constructed on top of Electron, it only works with Chrome-based browsers. Cypress interacts with the application under test through a socket connection while running in a separate process.

Browser Support

Chromium, Firefox, and WebKit are just a few of the browsers that Playwright supports. It makes it simpler to create cross-browser tests by providing a standard API for manipulating the browsers. On the other hand, Cypress only supports browsers built on the Chromium platform, such as Chrome, and Electron.

Speed

Because Playwright is built to execute tests concurrently, it can occasionally outperform Cypress. You can solve debugging by Playwright’s included system for collecting screenshots and videos of tests.

On the other hand, Cypress is made to be quick and has a real-time reload capability that enables you to view changes to the code right away. Moreover, Cypress has a dashboard that lets customers view test results in real-time, which is helpful for complicated projects.

API

The Playwright API is intended to be user-friendly and consistent across browsers. It offers both a low-level API for communicating directly with the browser and a high-level API for interacting with web items. As a result, you can write tests that are cross-browser compatible without having to worry about the particular implementation specifics of each browser.

Contrarily, Cypress has a more opinionated API that makes testing simpler. It passes chaining API requests that make writing understandable tests simple. The ability to interact with web components is also built-in into Cypress, making it simpler to develop tests without the need for low-level APIs.

Debugging

For debugging purposes, Playwright has a built-in capability for collecting screenshots and videos of tests. Moreover, it has a REPL (Read-Eval-Print Loop) that enables users to debug tests in real time.

Contrarily, Cypress offers a potent debugging environment that enables users to place breakpoints and walk through code in the browser. Moreover, Cypress offers a browser dev tools interface that enables users to view and interact with the application under test.

Test Runner

Although Playwright does not come with a built-in test runner, you can use it with well-known test runners like Jest and Mocha.

The built-in test runner offered by Cypress, on the other hand, makes it simpler to begin testing. Users of the Cypress test runner may view test results in real-time, which might be helpful for troubleshooting.
