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 Front-end components can be tested with Peridot	Yes You can test front-end components with kotest
Server-side Allows testing the bahovior of a server-side code	Yes Back-end componets and behaviours can be tested as small units	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 Peridot has several methods that allow one to create and define fixtures	Yes kotest contains fixtures, that is the setup / teardown functions
