What are the differences between Kotest and Spinach?

	Kotest https://github.com/kotest/kotest	Spinach https://github.com/codegram/spinach
Programming language	Kotlin	Ruby
Category	Unit Testing	Acceptance Testing
General info	kotest is a powerful, elegant and flexible test framework for Kotlin, formerly known as kotlintest Kotest has excellent support for data driven testing or table driven testing where it has the ability to quickly rerun the same test over and over with a predefined set of inputs and expected values	Spinach is a BDD framework on top of Gherkin Spinach is a high-level BDD framework that leverages the Gherkin language to help define executable specifications of your application or library's acceptance criteria.
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 front-end components with kotest	N/A
Server-side Allows testing the bahovior of a server-side code	Yes Yes, you can test back-end components with kotest	Yes You can test any server-side behaviour with Spinach
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes kotest contains fixtures, that is the setup / teardown functions	No
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 kotest has group fixtures available	No
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	Yes Spinach has inbuilt generator methods
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 You can use a third party library like mockk to create mocks	Yes Spinach can access the rspec-mocks methods
Grouping Allows organizing tests in groups	Yes You can create test suites with kotest	Yes Spinach Integrates with your RSpec test suite which allows declaring example groups and contexts.
