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

	Tacinga https://github.com/OwenMcDonnell/tacinga	Cucumber-JVM https://github.com/cucumber/cucumber-jvm
Programming language	Java	Java
Category	Unit Testing	Acceptance Testing
General info	Tacinga is an Object-Oriented Java unit testing library	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.		No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can unit test front-end components with tacinga	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 back-end components and functionality.with tacinga	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	N/A	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.	N/A	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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License (for non-commercial use); Commercial License (for commercial use)	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)	You can use external libraries like mockit	Yes By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)
Grouping Allows organizing tests in groups	N/A	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/
