What are the differences between Vows and Enhance PHP?

	Vows http://vowsjs.org/	Enhance PHP http://www.enhance-php.com/
Programming language	JavaScript	PHP
Category	Functional Testing, Asynchronous Testing	Unit Testing
General info	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.	Enhance PHP is a lightweight Open Source PHP unit testing framework It has support for mocks and stubs and runs in the browser, or via the command line
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	No	Yes It tests front-end functionality and can run in the browser
Server-side Allows testing the bahovior of a server-side code	Yes Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions	N/A
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	Yes One is able to write fixtures in Enhance PHP
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.	No	Yes One is able to write group fixtures in Enhance PHP
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	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 Enhance PHP has built-in support for mocks and stubs. You can set up expectations and supply predictable return values
Grouping Allows organizing tests in groups		Yes You can group tests into suites with Enhance PHP
