Unit Testing

General info

tap-producing test harness for node and browsers.

Tape API is a small superset of the node core assert module

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.

Yes

It does support xUnit output

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can write tests for any part of your front-end code to test any component or functionality

Yes

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

Yes

With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)

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

Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality

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

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)

No

Tape is a minimalistic framework that provides only essential features to make your assertions about your code

Yes

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

No

Tape contains only the essential features for making assertions on your code

Yes

You can create test suites with kotest
