Programming language

JavaScript

Category

Acceptance Testing

Unit Testing, Functional Testing

General info

JBehave is a Behaviour-Driven Development testing framework for java

JBehave is a Behaviour Driven Development framework. It intends to provide an intuitive and accessible way for automated acceptance testing

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 test front-end behaviour (scenarios) with JBehave

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

JBehave tests scenarios and behaviours of components, it can test back-end behaviour

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

You have a few options for using fixtures in JBehave: you can run your steps before/after each scenario by using LifeCycle: you can use @BeforeStory and @AfterStory annotations or you can define a dummy scenario with your setup/teardown steps

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 with JBehave

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.

No

Licence
Licence type governing the use and redistribution of the software

BSD-style license

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)

The best way to mock is to use third party libraries like Mockito, Jmock or Jmockit

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

N/A

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.
