General info

Nodeunit is a Nodejs testing framework that has Simple syntax, powerful tools. Nodeunit provides easy async unit testing for node.js and the browser.

Nodeunit was one of the first testing frameworks developed for node. It was very useful at the time, but there's an overwhelming number of other worthwhile testing solutions out there that are actively maintained. tap, ava, tape, mocha, jasmine, jest, ... the list goes on and on.

An assertion library for JavaScript (similar to chai.js)

N/A

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

Yes

Yes

Unit.js runs in the browser to test front-end components
Server-side
Allows testing the bahovior of a server-side code

Yes

Yes

Unit.js runs in nodejs to test server-side 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

Yes

Unit.js provides Test fixtures for running testsThis is one of its features
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

Yes

With Unit.js you can group your fixtures
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.
