General info

BDD testing framework for Go

Ginkgo is a BDD testing framework for Go that has a great matcher library to go with it called Gomega and intergrates with the standard testing library

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

Yes, by creating unit tests then testing individual front-end components

Yes

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

Yes

Yes by creating unit tests then testing various 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

N/A

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.

N/A

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.

Yes

They are available by running the command: 'ginko bootstrap'

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

Dvelopers can generate mocks by using the third party package 'gomock'

Yes

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

Yes

Ginkgo allows you to group tests in 'Describe' and 'Context' container blocks. It also provides 'It' and 'Specify' blocks to hold your assertions

Yes

You can create test suites with kotest
