General info

Futuristic, new, fast and concurrent JavaScript test runner with simple test syntax

AVA is a test runner for Node.js with a concise API, detailed error output. JS is a single-threaded but Node.JS is a parallel due to it's async behaviour. Ava leverages that and it can run tests concurrently

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.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML

Yes

It is an xUnit type testing framework
Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can write tests for the DOM with Ava, testing front-end components is easy with Ava

Yes

You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios
Server-side
Allows testing the bahovior of a server-side code

Yes

Ava utilizes the async I/O nature of Node and runs concurrent tests on NodeJs applications' back-endsA node server can have its endpoints tested with Ava

Yes

You can write unit tests to test server side behaviours and components using Jnario specs
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Using Ava's ava-fixture library it supports fixtures

Yes

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

Ava has support for group fixtures

Yes

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

AVA has no mocking built in, to mock functions you can use third party libraries like Sinon.js.

Yes

You can implement mocking through the use of a third partylibrary like Mockito
Grouping
Allows organizing tests in groups

No

There is no support for grouping tests

Yes

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