What are the differences between Needle and Vows?

Needle

Vows

Programming language

Java

JavaScript

Category

Unit Testing

Functional Testing, Asynchronous Testing

General info

Needle is a lightweight framework for testing Java EE components outside of the container in isolation

Needle reduces the test setup code by analysing dependencies and has automatic injection of mock objects by default. Therefore It will maximize the speed of development as well as the execution of unit tests

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.

No

No

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

Yes

You can test front-end components and functionality by testing individual front-end classes and functions

No

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

Yes

You can test back-end components and functionality.one of needles features is database testing via a JPA (Java Persistence API) like hibernate

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

Yes

It has setUp() and tearDown() functions which are mostly used to execute database operations

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.

Yes

The setUp() and tearDown functions can be used to define an environment for a group of tests

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)

Yes

One of needle's features is automatic injection of mock objects, it supports EasyMock and Mockito out of the box

Grouping
Allows organizing tests in groups
