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

	Kotest https://github.com/kotest/kotest	Wallaby https://github.com/elixir-wallaby/wallaby
Programming language	Kotlin	Elixir
Category	Unit Testing	Intergration Testing, Browser Automation
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	Library for end-to-end intergration testing for Elixir apps Wallaby supports concurrent feature testing (i.e multiple tests can run concurrently) as well as browser management
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 It works well for automated E2E testing; Wallaby also has an experimental Chrome Driver that works well
Server-side Allows testing the bahovior of a server-side code	Yes Yes, you can test back-end components with kotest	N/A
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	N/A
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	N/A
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	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 Available through third party libraries like Mock and Mockery
Grouping Allows organizing tests in groups	Yes You can create test suites with kotest	N/A
