General info

Javascript BDD (Behaviour Driven Development) based test runner/framework

Contextualised spec runner for JavaScript in the flavour of RSpec (Ruby Spec runner). JSSpec has got 2 really powerful features which helps you to make unit testing easier: 1) Shared examples 2) Shared contexts

Teenytest is a simple, zero-config test runner for NodeJS

Teenytest's CLI will run tests with zero public-API and zero configuration
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

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

Yes

JSSpec is primarily used for testing front-end/client-side components and functionality

No

Server-side
Allows testing the bahovior of a server-side code

No

Yes

Teenytest tests database connections and other server-side components and behaviour
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

N/A

Licence

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

It has a module doubles (mocks/spies) for mocking and spying

N/A
