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

	Cucumber-JVM https://github.com/cucumber/cucumber-jvm	Specter http://specter.sourceforge.net/
Programming language	Java	.NET
Category	Acceptance Testing	Acceptance 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.	Specter is a behaviour-driven development framework for .NET and Mono Specter enables behavior driven development (BDD) by allowing developers to write executable specifications for their objects, before actually implementing them, this is similar to test driven development however the different nomenclature makes it different from writing 'tests' for code that does not exist yet
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 You can test the front-end part like the GUI using cucumber with serenity, they integrate well to test your front-end.	Yes Developers can create specfications of the expected front-end behaviours and test them
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 Yes developers can create specfications of the expected back-end behaviours and test these.
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	N/A
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	N/A
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	BSD 3-Clause 'New' or 'Revised' 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 By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)	N/A
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 You can create your own test suites with specter
