Unitils vs Intern comparison of testing frameworks
What are the differences between Unitils and Intern?

	Unitils http://www.unitils.org/summary.html	Intern https://github.com/theintern/intern
Programming language	Java	JavaScript
Category	Unit Testing, Intergration Testing	Unit Testing, Functional Testing
General info	Unitils is an open source library whose goal is to make unit and integration testing easy and maintainable. Unitils is divided into modules, each of them providing support for a certain aspect of your unit and integration tests. For example if you need mocking for your tests, just include unitils-mock as a dependency, If you would also want to load DbUnit data sets, just include unitils-dbunit	Intern is minimal test system for JavaScript designed to write and run consistent. Intern is a complete test system for JavaScript designed to help you write and run consistent, high-quality test cases for your JavaScript libraries and applications. Using Intern we can write tests in JavaScript and TypeScript using any style like TDD, and BDD. Intern can run unit tests in most browsers that support ECMAScript
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 You can perform unit tests on various components and functionality that make up the front-end	Yes Intern is a complete test system for JavaScript It Runs in the browser and can test any front-end component and functionality
Server-side Allows testing the bahovior of a server-side code	Yes Unitils provides support for testing the back-end through modules such as DbUnit which specifically tests your database, i.e connections setup and so on	Yes Since it is a complete testing system that can test any type of JavaScript code, it can test server-side behaviour and components as well
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		N/A
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
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.
Licence Licence type governing the use and redistribution of the software		FreeBSD License
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)		Intern uses the Dojo Toolkit’s AMD loader. To mock, you should be able to just use the standard AMD 'map' feature, else you can use third party libraries like sinon.js
Grouping Allows organizing tests in groups		Yes You can group tests into Suites which may be specified as file paths or using glob expressions, there is typically one top-level suite per module.
