Vows vs fast-check comparison of testing frameworks
What are the differences between Vows and fast-check?

	Vows http://vowsjs.org/	fast-check https://github.com/dubzzz/fast-check
Programming language	JavaScript	JavaScript
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.	It's a property based testing framework written in typescript Fast-check provides another way to test programs by using property testing, Property testing is a way to test functionality by automatically generating many different inputs. This means Instead of relying on hard-coded inputs and outputs, it checks characteristics of the output given the whole range of possible inputs
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	N/A
Client-side Allows testing code execution on the client, such as a web browser	No	Yes It can test 'units' of front-end code for functionality and behaviour
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 It is a unit testing framework in essence and can test back-end functionality 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	N/A
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	N/A
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

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		N/A
