Atoum vs Kotest comparison of testing frameworks
What are the differences between Atoum and Kotest?

	Atoum http://atoum.org/	Kotest https://github.com/kotest/kotest
Programming language	PHP	Kotlin
Category	Unit Testing	Unit Testing
General info	Atoum is a unit testing framework specific to the PHP language Atoum is similar to SimpleTest and is designed to be implemented rapidly, simplify test development and allow for writing reliable, readable, and clear unit tests	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
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 Autom can perform unit tests on various front-end components and behaviours	Yes You can test front-end components with kotest
Server-side Allows testing the bahovior of a server-side code	Yes Autom can perform unit tests on servers/back-end components	Yes Yes, you can test back-end components with kotest
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By using the 'given()' method to setup your environment	Yes kotest contains fixtures, that is the setup / teardown functions
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 By using the 'given()' method to setup your environments	Yes kotest has group fixtures available
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	Atoum License	Apache License 2.0
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 use of autom mocks which are decoupled and easier to maintain	Yes You can use a third party library like mockk to create mocks
Grouping Allows organizing tests in groups	Yes By use of an extension for autom called blackfire which allows you to write blackfire test suites.	Yes You can create test suites with kotest
