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

	Vows http://vowsjs.org/	teenytest https://github.com/testdouble/teenytest
Programming language	JavaScript	JavaScript
Category	Functional Testing, Asynchronous 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.	Teenytest is a simple, zero-config test runner for NodeJS Teenytest's CLI will run tests with zero public-API and zero configuration
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It supports xUnit output
Client-side Allows testing code execution on the client, such as a web browser	No	No
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	Yes Teenytest tests database connections and other server-side components and behaviour
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	Yes It provides fixtures with the methods beforeAll(),afterEach() and afterAll()beforeAll() creates the browser and gives you a newPage() globalafterEach() will close any pages you created with newPage()afterAll() closes the browser
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 Teeny test supports grouping of 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.

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)		N/A
Grouping Allows organizing tests in groups		Yes Grouping is supported through nested tests in which any object can contain any combination of hooks, test functions, and additional sub-test objects.
