What are the differences between Kotest and teenytest?

	Kotest https://github.com/kotest/kotest	teenytest https://github.com/testdouble/teenytest
Programming language	Kotlin	JavaScript
Category	Unit 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	Teenytest is a simple, zero-config test runner for NodeJS Teenytest's CLI will run tests with zero public-API and zero configuration
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It supports xUnit output
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components with kotest	No
Server-side Allows testing the bahovior of a server-side code	Yes Yes, you can test back-end components with kotest	Yes Teenytest tests database connections and other server-side components and behaviour
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	Yes It provides fixtures with the methods beforeAll(),afterEach() and afterAll()beforeAll() creates the browser and gives you a newPage() globalafterEach() will close any pages you created with newPage()afterAll() closes the browser
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	Yes Teeny test supports grouping of fixtures

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	N/A
Grouping Allows organizing tests in groups	Yes You can create test suites with kotest	Yes Grouping is supported through nested tests in which any object can contain any combination of hooks, test functions, and additional sub-test objects.
