Selenium vs Playwright comparison of testing frameworks
What are the differences between Selenium and Playwright?

	Selenium https://pypi.org/project/selenium/	Playwright https://playwright.dev
Programming language	Python	JavaScript
Category	Web Automation	End-to-End Testing
General info	Selenium is an open source tool used to test web applications Selenium is a powerful testing tool which can send standard Python commands to different browsers, despite variations in browser design. It also provides extensions to emulate user interaction with browsers, a distribution server for scaling browser allocation, and the infrastructure for implementations of the W3C WebDriver specification that lets you write interchangeable code for all major web browsers	Test across all modern browsers. Use in your preferred language. Single API to automate Chromium, Firefox and WebKit. Use the Playwright API in JavaScript & TypeScript, Python, .NET and, Java.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes While using xUnit is supported, it does not support running parallel tests. https://playwright.dev/dotnet/docs/test-runners/#xunit-support
Client-side Allows testing code execution on the client, such as a web browser	Yes It is primarily a browser automation tool which tests front-end components and functionality	Yes Test on Chromium, Firefox and WebKit. Playwright has full API coverage for all modern browsers, including Google Chrome and Microsoft Edge (with Chromium), Apple Safari (with WebKit) and Mozilla Firefox. Cross-platform WebKit testing. With Playwright, test how your app behaves in Apple Safari with WebKit builds for Windows, Linux and macOS. Test locally and on CI. Test for mobile. Use device emulation to test your responsive web apps in mobile web browsers. Headless and headed. Playwright supports headless (without browser UI) and headed (with browser UI) modes for all browsers and all platforms. Headed is great for debugging, and headless is faster and suited for CI/cloud executions.
Server-side Allows testing the bahovior of a server-side code	Yes It can perform Unit tests and can test various components and behaviours in the backend using a BDD or TDD approach	Yes While running tests inside browsers you may want to make calls to the HTTP API of your application. It may be helpful if you need to prepare server state before running a test or to check some postconditions on the server after performing some actions in the browser. All of that could be achieved via APIRequestContext methods.
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By writing your Selenium WebDriver tests in PyTest, this gives you access to Pytest's powerful fixture model	Yes Playwright Test is based on the concept of the test fixtures. Test fixtures are used to establish environment for each test, giving the test everything it needs and nothing else. Test fixtures are isolated between tests, which gives Playwright Test following benefits: Playwright Test runs tests in parallel by default, making your test suite much faster; Playwright Test can efficiently retry the flaky failures, instead of re-running the whole suite; You can group tests based on their meaning, instead of their common setup.

Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	Yes One can group fixtures if accessing Pytest's fixture model	Yes You can group tests based on their meaning, instead of their common setup.
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.	Yes By using a library such as Faker or Fake-factory	Yes Playwright comes with the ability to generate tests out of the box. Generate tests; Preserve authenticated state; Record using custom setup; Emulate devices; Emulate color scheme and viewport size; Emulate geolocation, language and timezone.

Licence Licence type governing the use and redistribution of the software	Apache License 2.0	Apache License 2.0
Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	Yes It includes support for mocking	Yes Playwright introduces context-wide network interception to stub and mock network requests. You can mock API endpoints via handling the network quests in your Playwright script. Learn more at https://playwright.dev/docs/network/#handle-requests
Grouping Allows organizing tests in groups	Yes By using the TestNG feature with which we can create groups and maintain them easily	Yes You can group tests to give them a logical name or to scope before/after hooks to the group.
