General info

Jnario is a test framework for Java focusing on the design and documentation aspects of testing

Jnario is based on Xtend and consists of two domain-specific languages, one for writing readable acceptance tests, the other for succinct unit tests. Together they are well suited for behavior-driven development of Java programs.

Spek is a specification framework for Kotlin

Spek is a Kotlin-based Specification Testing framework for the JVM. It works as a JUnit 5 Test Engine meaning that we can easily plug it into any project that already uses JUnit 5 to run alongside any other tests that we might have.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It is an xUnit type testing framework

No

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

Yes

You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios

Yes

Yes you can test front-end behaviour by writing specifications to test front-end functionality. Developers can also write unit tests for individual front-end components.
Server-side
Allows testing the bahovior of a server-side code

Yes

You can write unit tests to test server side behaviours and components using Jnario specs

Yes

You can test back-end behaviour and componets by writing specifications to test back-end functionality and unit tests for individual back-end components
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

It contains the Setup & Teardown functions similar to JUnit but less verbose

Yes

Fixtures are available in spek through functions suchas beforeEachTest() and afterEachTest()
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

The Setup & Teardown functions can be used as group fixtures.

Yes

spek has group fixtures available through the beforeGroup() and afterGroup() functions
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.

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 implement mocking through the use of a third partylibrary like Mockito

Yes

You can use the third party library mockito-kotlin
Grouping
Allows organizing tests in groups

Yes

Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard

Yes

Tests are written using nested lambdas, each scope (level) can either be a group or a test
