Intern

Programming language

Java

JavaScript

Category

Intergration Testing, Functional Testing

Unit Testing, Functional Testing

General info

Arquillian is an Open source framework for writing Integration and functional tests

Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well

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.

Yes

It is a xUnit framework

No

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

Yes

You can perform unit tests on front-end components and functionality

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

You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions

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

Yes

By use of extensions, for example you can use the Persistence extension to set database fixtures

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.

Yes

You can define group fixtures

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.

N/A

Licence
Licence type governing the use and redistribution of the software

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

Arquillian supports mock object functionality you can use third party libraries

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

Arquilian supports grouping of tests

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.
