General info

Turnip is a Gherkin extension for RSpec

Turnip is an open source Ruby gem that provides a platform for acceptance tests.It combines Gherkin, a language defined by the Cucumber Behavior-Driven Development (BDD) tool to express requirements, and RSpec, an open source BDD tool for Ruby developers.

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

Turnip can perform end-to-end tests therefore test front-end components and functionality

Yes

You can test front-end components with kotest
Server-side
Allows testing the bahovior of a server-side code

Yes

Turnip is used to test server-side behaviour and 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

No

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.

No

No

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 intergrating with RSpec turnip has access to the rspec-mocks gem

Yes

You can use a third party library like mockk to create mocks
Grouping
Allows organizing tests in groups

Yes

Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.

Yes

You can create test suites with kotest
