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

	SpecFlow https://specflow.org/	Behat https://docs.behat.org/en/latest/
Programming language	.NET	PHP
Category	Acceptance Testing	Functional/Acceptance 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.	Behat is an open source Behavior-Driven Development framework for PHP. Behat uses the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD); This means the tests we write with Behat look rather like stories than code. It is inspired by Ruby's Cucumber
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end behaviour is tested. With specflow specifications of the expected behaviours are made and specflow tests against this	Yes To enable Behat to test a website, you need to add Mink and a browser emulator (selenium maybe, though slow) to the mix. Mink methods are the connector between Behat and an extensive list of available drivers, and they provide a consistent testing API.
Server-side Allows testing the bahovior of a server-side code	Yes Back-end behaviour is tested. Specifications of the expected behaviours are made and specflow tests against them	Yes Behat can be used for Data Integrity Testing to verify that database operations are functioning properly
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes BeforeTestRun and AfterTestRun are executed once for each thread which is a limitation of the current architecture.	Yes One can use the 'Doctrinefixturesbundle' to create the required fixture loaders and load them in our Behat scenarios when required, using the 'BeforeScenario' hook.
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.	N/A	Yes Behat allows for group fixtures
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 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	By use of third party libraries like moodle-behat-generators
Licence Licence type governing the use and redistribution of the software	BSD license	MIT License
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 Specflow intergrates well with mock to give it excellent mocking capabilities	By using third party libraries like Mock and Prophecy
Grouping Allows organizing tests in groups	Yes You can create test suites with specflow	Yes You can use tags to group features and scenarios together, independent of your file and directory structure
