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

	SpecFlow https://specflow.org/	Kahlan https://github.com/kahlan/kahlan
Programming language	.NET	PHP
Category	Acceptance Testing	Unit 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.	Kahlan is a full-featured BDD testing framework It is a full-featured BDD testing framework that embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan makes it possible to write unit tests using the 'describe-it' syntax and requires at least PHP 5.5
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 Kahlan allows you to test front-end components and behaviour easily
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 You can test individual back-end components using Kahlan
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 Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method
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 You can write 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	N/A
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	Yes With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)
Grouping Allows organizing tests in groups	Yes You can create test suites with specflow	Yes Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping
