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

	AVA https://github.com/avajs/ava	Needle http://needle.spree.de/
Programming language	JavaScript	Java
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	Needle is a lightweight framework for testing Java EE components outside of the container in isolation Needle reduces the test setup code by analysing dependencies and has automatic injection of mock objects by default. Therefore It will maximize the speed of development as well as the execution of unit tests
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	No
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 test front-end components and functionality by testing individual front-end classes and functions
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 test back-end components and functionality.one of needles features is database testing via a JPA (Java Persistence API) like hibernate
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 has setUp() and tearDown() functions which are mostly used to execute database operations
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() and tearDown functions can be used to define an environment for a group of tests
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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	GNU Lesser General Public License v2.1
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 One of needle's features is automatic injection of mock objects, it supports EasyMock and Mockito out of the box
Grouping Allows organizing tests in groups	No There is no support for grouping tests	N/A
