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

	AVA https://github.com/avajs/ava	fast-check https://github.com/dubzzz/fast-check
Programming language	JavaScript	JavaScript
Category	Unit Testing, Intergration Testing	Unit Testing
General info	Futuristic, new, fast and concurrent JavaScript test runner with simple test syntax AVA is a test runner for Node.js with a concise API, detailed error output. JS is a single-threaded but Node.JS is a parallel due to it's async behaviour. Ava leverages that and it can run tests concurrently	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 However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can write tests for the DOM with Ava, testing front-end components is easy with Ava	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 Ava utilizes the async I/O nature of Node and runs concurrent tests on NodeJs applications' back-endsA node server can have its endpoints tested with Ava	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	Yes Using Ava's ava-fixture library it supports fixtures	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.	Yes Ava has support for group fixtures	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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	MIT License
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)	AVA has no mocking built in, to mock functions you can use third party libraries like Sinon.js.	N/A
Grouping Allows organizing tests in groups	No There is no support for grouping tests	N/A
