JGiven vs Vows comparison of testing frameworks
What are the differences between JGiven and Vows?

	JGiven http://jgiven.org/	Vows http://vowsjs.org/
Programming language	Java	JavaScript
Category	Acceptance Testing	Functional Testing, Asynchronous Testing
General info	JGiven is a BDD tool for Java in plain java. With JGiven Developers write scenarios in plain Java using a fluent, domain-specific API, JGiven generates reports that are readable by domain experts.	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 UI functionality or behaviour by writing scenarios that cover front-end behaviour	No
Server-side Allows testing the bahovior of a server-side code	Yes You can write 'scenarios' to test server-side behaviours	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		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.	N/A
Licence Licence type governing the use and redistribution of the software		Apache License 2.0
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 You can use third party libraries such as JMock and JMockit to mock objects and functions
Grouping Allows organizing tests in groups
