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.

Vows is a testing framework for NodeJS applications.

Vows supports Asynchronous BDD & continuous testing for two reasons first, reason is that node.js is asynchronous, and therefore our tests need to be, second,is to make test suites which target I/O libraries run much faster.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

No

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

Yes

No

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

Yes

Yes

Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

No

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

No

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.

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)

Grouping
Allows organizing tests in groups
