xUnit.net vs Cucumber-JVM comparison of testing frameworks
What are the differences between xUnit.net and Cucumber-JVM?

	xUnit.net https://xunit.net/	Cucumber-JVM https://github.com/cucumber/cucumber-jvm
Programming language	.NET	Java
Category	Unit Testing	Acceptance Testing
General info	xUnit.net is aUnit testing framework for C# and .NET xUnit.net is a free, open source, community-focused unit testing tool for the .NET Framework. It is used to test C#, F#, VB.NET and other .NET languages. xUnit.net and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes xUnit.net is part of the xUnit family of frameworks	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test various front-end components independently since it is a Unit testing framework	Yes You can test the front-end part like the GUI using cucumber with serenity, they integrate well to test your front-end.
Server-side Allows testing the bahovior of a server-side code	Yes You can test various back-end components independently since it is a Unit testing framework	Yes You can test back-end components such as API's using rest&soap clients, and databases
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes It contains class fixtures which are setup once pertest class	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
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 xUnit.net contains collection fixtures which allow you to share context among many tests	Yes You can group your fixtures inside your fixtures directories
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
Licence Licence type governing the use and redistribution of the software		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 By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)
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/
