What are the differences between Kotest and Kahlan?

	Kotest https://github.com/kotest/kotest	Kahlan https://github.com/kahlan/kahlan
Programming language	Kotlin	PHP
Category	Unit Testing	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	Kahlan is a full-featured BDD testing framework It is a full-featured BDD testing framework that embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan makes it possible to write unit tests using the 'describe-it' syntax and requires at least PHP 5.5
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	Yes Kahlan allows you to test front-end components and behaviour easily
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 individual back-end components using Kahlan
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 Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method
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 You can write group fixtures
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

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 With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)
Grouping Allows organizing tests in groups	Yes You can create test suites with kotest	Yes Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping
