Cucumber-JVM vs Jnario comparison of testing frameworks
What are the differences between Cucumber-JVM and Jnario?

	Cucumber-JVM https://github.com/cucumber/cucumber-jvm	Jnario http://jnario.org/
Programming language	Java	Java
Category	Acceptance Testing	Acceptance Testing, Unit Testing
General info	Cucumber-JVM is a pure Java implementation of Cucumber The specifications are written in plain texts, which allows them to be easily understandable by all stakeholders.	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 You can test the front-end part like the GUI using cucumber with serenity, they integrate well to test your front-end.	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 You can test back-end components such as API's using rest&soap clients, and databases	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 Using the cucumber extension aruba you can create fixures in two steps: 1.Create a fixtures-directory; 2.Create fixture files in this directory	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.	Yes You can group your fixtures inside your fixtures directories	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.	N/A	N/A
Licence Licence type governing the use and redistribution of the software	MIT 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 By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)	Yes You can implement mocking through the use of a third partylibrary like Mockito
Grouping Allows organizing tests in groups	Yes Cucumber allows the use of tag Cucumber feature files or individual tests to group tests. Then, you can pass a Cucumber tagged expression at test execution that specifies the tag (grouped) tests to run. https://www.toolsqa.com/cucumber/cucumber-tags/	Yes Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard
