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

Acceptance Testing

End-to-End Testing

General info

SpecFlow is a test automation solution for .NET

SpecFlow is a test automation solution for .NET which follows the BDD paradigm, and is part of the Cucumber family. SpecFlow tests are written with Gherkin, using the official Gherkin parser which allows you to write test cases using natural languages and supports over 70 languages.

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.
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.



While using xUnit is supported, it does not support running parallel tests. https://playwright.dev/dotnet/docs/test-runners/#xunit-support
Allows testing code execution on the client, such as a web browser


Front-end behaviour is tested. With specflow specifications of the expected behaviours are made and specflow tests against this


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.
Allows testing the bahovior of a server-side code


Back-end behaviour is tested. Specifications of the expected behaviours are made and specflow tests against them


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.
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


BeforeTestRun and AfterTestRun are executed once for each thread which is a limitation of the current architecture.


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.



You can group tests based on their meaning, instead of their common setup.
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.


SpecFlow contains a generator component. The SpecFlow IDE integration tries to locate the generator component in your project structure, in order to use the generator version matching the SpecFlow runtime in your project


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. Learn more at https://playwright.dev/docs/codegen/

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)


Specflow intergrates well with mock to give it excellent mocking capabilities


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
Allows organizing tests in groups


You can create test suites with specflow


You can group tests to give them a logical name or to scope before/after hooks to the group.
