AVA vs JasUnit comparison of testing frameworks
What are the differences between AVA and JasUnit?

	AVA https://github.com/avajs/ava	JasUnit http://jster.net/library/jasunit
Programming language	JavaScript	JavaScript
Category	Unit Testing, Intergration Testing	Unit Testing
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	JasUnit is a slim unit testing framework for JavaScript, following the general design principles of xUnit. For testing your code, JasUnit allows you to: Create test fixtures with any number of test methods; Implement setup() and teardown() methods which are run before and after each test; Specify a namespace for a fixture for easy organisation of tests; Use the default or custom logger (default appends results to a given element); Use assertions from any scope - this isn't necessary or even really advised, but some people prefer it.
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 JasUnit follows the general design principles o xUnit
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 JasUnit is primarily used to test front-end code and functionality
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	No
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 With JasUnit you can Create test fixtures with any number of test methods Implement setup() and teardown() methods which are run before and after each test
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 JasUnit allow you to create 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.	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	N/A
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 It provides inbuilt Mocking capabilities
Grouping Allows organizing tests in groups	No There is no support for grouping tests	N/A
