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

	SpecFlow https://specflow.org/	Jnario http://jnario.org/
Programming language	.NET	Java
Category	Acceptance Testing	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.	Jnario is a test framework for Java focusing on the design and documentation aspects of testing Jnario is based on Xtend and consists of two domain-specific languages, one for writing readable acceptance tests, the other for succinct unit tests. Together they are well suited for behavior-driven development of Java programs.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is an xUnit type testing framework
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 You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios
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 write unit tests to test server side behaviours and components using Jnario specs
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 It contains the Setup & Teardown functions similar to JUnit but less verbose
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 The Setup & Teardown functions can be used as 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	Eclipse Public License v1.0
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 Specflow intergrates well with mock to give it excellent mocking capabilities	Yes You can implement mocking through the use of a third partylibrary like Mockito
Grouping Allows organizing tests in groups	Yes You can create test suites with specflow	Yes Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard
